February 9 in History

Zeno (; Latin: Zeno; Ancient Greek: Ζήνων, romanized: Zēnōn; c. 425 – 9 April 491) was Eastern Roman emperor from 474 to 475 and again from 476 to 491. His reign was plagued by domestic revolts and religious dissension, but was more successful on the foreign front. He is credited with further stabilizing the Eastern empire, while the Western Roman Empire fell following the deposition of Romulus Augustulus. Born in Isauria, Zeno was known as Tarasis before adopting his Roman name and becoming an ally of Emperor Leo I, who saw the Isaurian general as an important counterweight against the Germanic leader Aspar. In 466, he married Leo I's daughter, Ariadne, with whom he had a son, Leo. On the death of Leo I in 474, Zeno's seven-year-old son took the throne as Leo II, with Zeno made co-emperor shortly after. Leo II died of an illness later that year, leaving Zeno as the sole emperor. Despite his early success in making peace with the Vandals, Zeno was an unpopular emperor due to his barbarian origins. In early 475, he was forced to flee Constantinople in a revolt orchestrated in part by dowager Empress Verina, which concluded with Leo I's brother-in-law Basiliscus installing himself as emperor. Seeking refuge in his native Isauria, Zeno later took advantage of Basiliscus's own flagging popularity, convinced the generals Illus and Armatus to defect, marched on the capital and reclaimed the throne in mid-476. Meanwhile, in the western empire, Germanic leader Odoacer deposed the final Western Roman emperor, Romulus Augustulus, and sent the imperial regalia to Constantinople. He expressly acknowledged the suzerainty of Zeno over the West, making Zeno the theoretical sole ruler of a reunified empire. In return, Zeno recognised Odoacer's de facto reign in Italy. In the late 470s and 480s Zeno faced several revolts, including one from his brother-in-law Marcianus and one from Illus, both of which he ultimately suppressed. He also attempted to deal with hostilities from the two Ostrogothic leaders, Theodoric the Amal (Theodoric the Great) and Theodoric Strabo, by playing them against each other. Following Strabo's early death, Zeno was able to achieve a lasting peace with Theodoric by sending him to Italy, where he defeated Odoacer and established the Ostrogothic Kingdom. In religious matters, Zeno issued the Henotikon in 482 on the advice of Acacius, the Patriarch of Constantinople, in an unsuccessful attempt to reconcile the differences between the Chalcedonians and the Miaphysites over the nature of Christ. Pope Felix III condemned the document and excommunicated Acacius in 484, beginning the Acacian schism which lasted until 519. Zeno died without an heir in 491 and was succeeded by Anastasius I Dicorus, a courtier chosen by Empress Ariadne.

Boleslaus III (c. 965 – 1037), called the Red (Czech: Boleslav III. Ryšavý; to denote a "red-haired" individual) or the Blind, a member of the Přemyslid dynasty, was Duke of Bohemia from 999 until 1002 and briefly again during the year 1003. During his chaotic reign, Bohemia became a pawn in the long German–Polish War between King Henry II and Duke Bolesław I, "the Brave", of Poland.

The First Crusade (1096–1099) was the first of a series of religious wars, or Crusades, which were initiated, supported and at times directed by the Latin Church in the Middle Ages. Their aim was to return the Holy Land to Christian rule after its conquest by the Rashidun Caliphate in the 7th century. By the 11th century, although Jerusalem had then been ruled by Muslims for hundreds of years, the practices of the Seljuk rulers in the region began to threaten local Christian populations, pilgrimages from the West, and the Byzantine Empire itself. The earliest impetus for the First Crusade came in 1095 when Byzantine emperor Alexios I Komnenos sent ambassadors to the Council of Piacenza to request military support in the empire's conflict with the Seljuk-led Turks. This was followed later in the year by the Council of Clermont, at which Pope Urban II gave a speech supporting the Byzantine request and urging faithful Christians to undertake an armed pilgrimage to Jerusalem.

Chester Racecourse, also known as the Roodee, is a racecourse located in Chester, England. The horse racing venue is officially recognised by Guinness World Records as the "oldest racecourse still in operation". Horse racing in Chester started in the early sixteenth century, with 1539 cited as the year racing began, although some sources give a date of 1512 for the first races in Chester. It is also thought to be the smallest racecourse of significance in England at 1 mile and 1 furlong (1.8 km) long.

The Bishop of Gloucester is the ordinary of the Church of England Diocese of Gloucester in the Province of Canterbury.

Pope Gregory XV (Latin: Gregorius XV; Italian: Gregorio XV; 9 January 1554 – 8 July 1623), born Alessandro Ludovisi, was the head of the Catholic Church and ruler of the Papal States from 9 February 1621 until his death in 1623. He is notable for founding the Congregation for the Propagation of the Faith, an organization tasked with overseeing the spread of Catholicism and missionary work. Gregory XV was also responsible for the canonization of Saints Ignatius of Loyola, Francis Xavier, Teresa of Ávila, and Philip Neri, which solidified his commitment to the Counter-Reformation.

The Capture of Fort Rocher took place on 9 February 1654, during the Franco-Spanish War (1635–1659). Equipped with one siege battery, a Spanish expedition of 700 troops attacked the buccaneer stronghold of Tortuga, capturing the Fort de Rocher and 500 prisoners including 330 buccaneers and goods valued at approximately 160,000 pieces-of-eight. The Spanish burned the colony to the ground and slaughtered its inhabitants, leaving behind a fort manned by 150 soldiers. They possessed the island for about eighteen months, but on the approach of the expedition under Penn and Venables were ordered by the Conde de Peñalva, Governor of Santo Domingo, to demolish the fortifications, bury the artillery and other arms, and retire to his aid in Hispaniola.

The American Revolutionary War (April 19, 1775 – September 3, 1783), also known as the Revolutionary War or American War of Independence or simply the American Revolution, was the armed conflict that comprised the final eight years of the broader American Revolution, in which American Patriot forces organized as the Continental Army and, commanded by George Washington, defeated the British Army. The conflict was fought in North America, the Caribbean, and the Atlantic Ocean. The war's outcome seemed uncertain for most of the war, but Washington and the Continental Army's decisive victory in the Siege of Yorktown in 1781 led King George III and the Kingdom of Great Britain to negotiate an end to the war. In 1783, in the Treaty of Paris, the British monarchy acknowledged the independence of the Thirteen Colonies, leading to the establishment of the United States as an independent and sovereign nation. In 1763, after the British Empire gained dominance in North America following its victory over the French in the Seven Years' War, tensions and disputes began escalating between the British and the Thirteen Colonies, especially following passage of the Stamp and Townshend Acts. The British Army responded by seeking to occupy Boston militarily, leading to the Boston Massacre on March 5, 1770. In mid-1774, with tensions escalating even further between the British Army and the colonies, the British Parliament imposed the Intolerable Acts, an attempt to disarm Americans, leading to the Battles of Lexington and Concord in April 1775, the first battles of the Revolutionary War. In June 1775, the Second Continental Congress voted to incorporate colonial-based Patriot militias into a central military, the Continental Army, and unanimously appointed Washington its commander-in-chief. Two months later, in August 1775, George III declared the colonies to be in a state of rebellion. In July 1776, the Second Continental Congress formalized the war, passing the Lee Resolution on July 2, and, two days later, unanimously adopting the Declaration of Independence, on July 4. In March 1776, in an early win for the newly-formed Continental Army under Washington's command, following a successful siege of Boston, the Continental Army successfully drove the British Army out of Boston. British commander in chief William Howe responded by launching the New York and New Jersey campaign, which resulted in Howe's capture of New York City in November. Washington responded by clandestinely crossing the Delaware River and winning small but significant victories at Trenton and Princeton. In the summer of 1777, as Howe was poised to capture Philadelphia, the Continental Congress fled to Baltimore. In October 1777, a separate northern British force under the command of John Burgoyne was forced to surrender at Saratoga in an American victory that proved crucial in convincing France and Spain that an independent United States was a viable possibility. France signed a commercial agreement with the revolutionaries, followed by a Treaty of Alliance in February 1778. In 1779, the Sullivan Expedition undertook a scorched earth campaign against British-allied factions of the Haudenosaunee Confederacy (also Iroquois). Native American raids on the American frontier, however, continued to be a problem. Also, in 1779, Spain allied with France against Great Britain in the Treaty of Aranjuez, though Spain did not formally ally with the Americans. Howe's replacement Henry Clinton intended to take the war against the Americans into the Southern Colonies. Despite some initial success, British General Cornwallis was besieged by a Franco-American army in Yorktown, Virginia, in September and October 1781. The French navy cut off Cornwallis's escape and he was forced to surrender in October. The British wars with France and Spain continued for another two years, but fighting largely ceased in North America. In the Treaty of Paris, signed on September 3, 1783, Great Britain acknowledged the sovereignty and independence of the United States, bringing the American Revolutionary War to an end. The Treaties of Versailles resolved Great Britain's conflicts with France and Spain, and forced Great Britain to cede Tobago, Senegal, and small territories in India to France, and Menorca, West Florida, and East Florida to Spain.

Rhode Island ( ROHD) is a state in the New England region of the Northeastern United States. It borders Connecticut to its west; Massachusetts to its north and east; and the Atlantic Ocean to its south via Rhode Island Sound and Block Island Sound; and shares a small maritime border with New York, east of Long Island. Rhode Island is the smallest U.S. state by area and the seventh-least populous, with slightly more than 1.11 million residents as of 2025. The state's population, however, has continually recorded growth in every decennial census since 1790, and it is the second-most densely populated state after New Jersey. The state takes its name from the eponymous island, though most of its land area is on the mainland. Providence is its capital and most populous city. Native Americans lived around Narragansett Bay before English settlers began arriving in the early 17th century. Rhode Island was unique among the Thirteen British Colonies in having been founded by a refugee, Roger Williams, who fled religious persecution in the Massachusetts Bay Colony to establish a haven for religious liberty. He founded Providence in 1636 on land purchased from local tribes, creating the first settlement in North America with an explicitly secular government. The Colony of Rhode Island and Providence Plantations subsequently became a destination for religious and political dissenters and social outcasts, earning it the moniker "Rogue's Island". Rhode Island was the first colony to call for a Continental Congress, in 1774, and the first to renounce its allegiance to the British Crown, on May 4, 1776. After the American Revolution, during which it was heavily occupied and contested, Rhode Island became the fourth state to ratify the Articles of Confederation, on February 9, 1778. Because its citizens favored a weaker central government, it boycotted the 1787 convention that had drafted the United States Constitution, which it initially refused to ratify; it finally ratified it on May 29, 1790, the last of the original 13 states to do so. The state was officially named the State of Rhode Island and Providence Plantations since the colonial era but came to be commonly known as "Rhode Island". On November 3, 2020, the state's voters approved an amendment to the state constitution formally dropping "and Providence Plantations" from its full name. Its official nickname, found on its welcome sign, is the "Ocean State", a reference to its 400 mi (640 km) of coastline and the large bays and inlets that make up about 14% of its area.

Haiti, officially the Republic of Haiti, is a country in the Caribbean on the island of Hispaniola in the Caribbean Sea, east of Cuba and Jamaica and south of The Bahamas. It occupies the western side of the island, which it shares with the Dominican Republic. Haiti is the third largest country in the Caribbean by area, and with an estimated population of 11.4 million, it is the most populous Caribbean country. The capital and largest city is Port-au-Prince. Haiti was originally inhabited by Indigenous peoples, known as the Taíno. In 1492, Christopher Columbus established the first European settlement in the Americas, La Navidad, on its northeastern coast. The island was part of the Spanish Empire until 1697, when the western portion was ceded to France and became Saint-Domingue, dominated by sugarcane plantations worked by enslaved Africans. The 1791–1804 Haitian Revolution made Haiti the first sovereign state in the Caribbean, the second republic in the Americas, the first country in the Americas to officially abolish slavery, and the only country in history established by a slave revolt. The independent state began as an empire, later splitting into two nations before reunifying in 1820; a second empire was established under Faustin Soulouque before the return of the republic in 1859. The 19th century also saw political instability, international isolation, a crippling debt to France, and failed invasions of the Dominican Republic, including a costly war. U.S. forces occupied Haiti from 1915 to 1934, followed by the dictatorial rule of the Duvalier family (1957–1986). Following a coup d'état in 1991, a U.S.-led multinational force intervened in 1994; a second coup in 2004 was followed by a United Nations intervention. In the 2010s, a catastrophic earthquake and a large-scale cholera outbreak devastated the country. Historically poor and politically unstable, Haiti has faced severe economic and political crises, gang activity displacing over 1.3 million, and the collapse of its government. The presidency has been vacant since the 2021 assassination of Jovenel Moïse, while the National Assembly and the judiciary have been rendered inoperative, leaving the country in virtual anarchy with almost nonexistent state control. One of the world's least developed countries and with no elected officials remaining, Haiti has been described as a failed state. Haiti is a founding member of the United Nations, Organization of American States, Association of Caribbean States, and the Organisation internationale de la Francophonie. In addition to CARICOM, it is a member of the International Monetary Fund, World Trade Organization, and Community of Latin American and Caribbean States.

In the United States, the Electoral College is the group of presidential electors that is formed every four years for the sole purpose of voting for the president and vice president in the presidential election. This process is described in Article Two of the Constitution. The number of electors from each state is equal to that state's congressional delegation which is the number of senators (two) plus the number of Representatives for that state. Each state appoints electors using legal procedures determined by its legislature. Federal office holders, including senators and representatives, cannot be electors. Federal agencies provide step-by-step descriptions of how electors are appointed, meet in December, and how Congress counts the electoral votes. Additionally, the Twenty-third Amendment granted the federal District of Columbia three electors (bringing the total number from 535 to 538). A simple majority of electoral votes (270 or more) is required to elect the president and vice president. If no candidate achieves a majority, a contingent election is held by the House of Representatives, to elect the president, and by the Senate, to elect the vice president. The states and the District of Columbia hold a statewide or district-wide popular vote on Election Day in November to choose electors based upon how they have pledged to vote for president and vice president, with some state laws prohibiting faithless electors. All states except Maine and Nebraska use party block voting, or general ticket method, to choose their electors, meaning all their electors go to one winning ticket. Maine and Nebraska choose one elector per congressional district and two electors for the ticket with the highest statewide vote. The electors meet and vote in December, and the inaugurations of the president and vice president take place in January. Political science research finds that winner-take-all allocation tends to concentrate presidential campaign visits and advertising in a small number of competitive "swing" states, while noncompetitive states receive comparatively less attention. The merit of the electoral college system has been a matter of ongoing debate in the United States since its inception at the Constitutional Convention in 1787, becoming more controversial by the latter years of the 19th century, up to the present day. More resolutions have been submitted to amend the Electoral College mechanism than any other part of the constitution. An amendment that would have abolished the system was approved by the House in 1969, but failed to move past the Senate. Supporters argue that it requires presidential candidates to have broad appeal across the country to win, while critics argue that it is not representative of the popular will of the nation. Public opinion polling has found that about two-thirds of Americans support replacing the Electoral College with a national popular vote.

The Roman Republic (Italian: Repubblica Romana) was a short-lived state declared on 9 February 1849, when the government of the Papal States was temporarily replaced by a republican government due to Pope Pius IX's departure to Gaeta. The republic was led by Carlo Armellini, Giuseppe Mazzini, and Aurelio Saffi. Together they formed a triumvirate, a reflection of a form of government during the first century BC crisis of the Roman Republic. One of the major innovations the Republic hoped to achieve was enshrined in its constitution: freedom of religion, with Pope Pius IX and his successors guaranteed the right to govern the Catholic Church. These religious freedoms were quite different from the situation under the preceding government, which allowed only Catholicism and Judaism to be practised by its citizens. The Constitution of the Roman Republic was the first in the world to abolish capital punishment in its constitutional law.

The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States between the Union ("the North") and the Confederacy ("the South"), which was formed in 1861 by states that had seceded from the Union to preserve slavery in the United States. The South saw slavery as threatened because of the election of Abraham Lincoln and the growing abolitionist movement in the North. The war ended with Union victory, the dissolution of the Confederacy and the abolition of slavery, freeing four million African Americans. Decades of controversy over slavery came to a head when Abraham Lincoln, a Republican who opposed slavery's expansion, won the 1860 presidential election. Seven slave states in the South responded to Lincoln's victory by seceding from the United States and forming the Confederate States of America. The Confederacy seized US forts and other federal assets in the South. The war began on April 12, 1861, when the Confederacy bombarded Fort Sumter in South Carolina. A wave of enthusiasm for war swept over the North and South, as military recruitment soared. Four more Southern states seceded after the war began and, led by its president, Jefferson Davis, the Confederacy comprised eleven states, containing a third of the US population. Four years of intense combat, mostly in the South, ensued. During 1861–1862 in the western theater, the Union made permanent gains, though in the eastern theater the conflict was inconclusive. The abolition of slavery became a Union war goal on January 1, 1863, when Lincoln issued the Emancipation Proclamation, which declared all slaves in rebel states to be free, applying to more than 3.5 million of the 4 million enslaved people in the country. To the west, the Union first destroyed the Confederacy's river navy by the summer of 1862, then much of its western armies, and seized New Orleans. The successful 1863 Union siege of Vicksburg split the Confederacy in two at the Mississippi River, while Confederate general Robert E. Lee's incursion north failed at the Battle of Gettysburg. General Ulysses S. Grant's western successes led Lincoln to promote him to command of all Union armies in 1864. Inflicting an ever-tightening naval blockade of Confederate ports, the Union marshaled resources and manpower to attack the Confederacy from all directions. This led to the fall of Atlanta in 1864 to Union general William Tecumseh Sherman, followed by his March to the Sea, which culminated in his taking Savannah. The last significant battles raged around the ten-month siege of Petersburg, gateway to the Confederate capital of Richmond. The Confederates abandoned Richmond, and on April 9, 1865, Lee surrendered to Grant following the Battle of Appomattox Court House, setting in motion the end of the war. Lincoln lived to see this victory but was shot by an assassin on April 14, dying the next day. By the end of the war, much of the South's infrastructure had been destroyed. The Confederacy collapsed, the Thirteenth Amendment abolished slavery, and four million enslaved black people were freed. The war-torn nation then entered the Reconstruction era in an attempt to rebuild the country, bring the former Confederate states back into the United States, and grant civil rights to freed slaves. The war is one of the most extensively studied and written about episodes in the history of the United States. It remains the subject of cultural and historiographical debate. Of continuing interest is the myth of the Lost Cause of the Confederacy. The war was among the first to use industrial warfare. Railroads, the electrical telegraph, steamships, the ironclad warship, and mass-produced weapons were widely used. The war left an estimated 700,000 soldiers dead, along with an undetermined number of civilian deaths, making it the deadliest in American history. The technology and brutality of the Civil War foreshadowed the coming world wars.

Ulysses S. Grant (born Hiram Ulysses Grant; April 27, 1822 – July 23, 1885) was the 18th president of the United States, serving from 1869 to 1877, and was the Commanding General of the Union Army, leading it to victory in the American Civil War in 1865. Grant was born in Ohio and graduated from the United States Military Academy in 1843. He served with distinction in the Mexican–American War, but returned to civilian life impoverished in 1854. In 1861, shortly after the Civil War began, Grant joined the Union Army. He rose to prominence after securing victories in the western theater in 1862. In 1863, he led the Vicksburg campaign that gave Union forces control of the Mississippi River and dealt a major strategic blow to the Confederacy. President Abraham Lincoln promoted Grant to lieutenant general and command of all Union armies after his victory at Chattanooga. Grant fought Robert E. Lee through the Overland Campaign, which ended when Lee surrendered to Grant at Appomattox. In 1866, President Andrew Johnson promoted Grant to General of the Army. Grant broke with Johnson over Reconstruction policies. A war hero, drawn in by his sense of duty, Grant was unanimously nominated by the Republican Party and elected president in 1868. As president, Grant stabilized the post-war economy, supported Reconstruction and the Fifteenth Amendment, and prosecuted the Ku Klux Klan. An effective civil rights executive, Grant signed a bill to create the United States Department of Justice and worked with Radical Republicans to protect African Americans. In 1871, he created the first Civil Service Commission. Grant was re-elected in the 1872 presidential election, but was inundated by executive scandals during his second term. His response to the Panic of 1873 was ineffective in halting the Long Depression, which contributed to the Democrats winning the House majority in 1874. Grant's Native American policy was to assimilate Indians into Anglo-American culture. In his foreign policy, the Alabama Claims against Britain were peacefully resolved, but the Senate rejected his proposal to annex Santo Domingo. During the disputed 1876 presidential election, he facilitated the approval by Congress of a compromise. Leaving office in 1877, Grant undertook a world tour, becoming the first president to circumnavigate the world. In 1880, he was unsuccessful in obtaining the Republican nomination for a third term. In 1885, dying of throat cancer, Grant wrote his memoirs, which were posthumously published and became a major critical and financial success. At his death, he was the most popular American and was memorialized as a symbol of national unity. Due to the pseudohistorical and negationist mythology of the Lost Cause of the Confederacy spread by Confederate sympathizers around the turn of the 20th century, historical assessments and rankings of Grant's presidency suffered considerably before they began recovering in the 21st century.

Stephen Grover Cleveland (March 18, 1837 – June 24, 1908) was the 22nd and 24th president of the United States, serving from 1885 to 1889 and from 1893 to 1897. He was the first Democrat elected president after the American Civil War and the first U.S. president to serve nonconsecutive terms. Born in Caldwell, New Jersey, Cleveland was elected mayor of Buffalo in 1881 and governor of New York in 1882. While governor, he closely cooperated with state assembly minority leader Theodore Roosevelt to pass reform measures, winning national attention. He led the Bourbon Democrats, a pro-business movement opposed to high tariffs, free silver, inflation, imperialism, and subsidies to businesses, farmers, or veterans. His crusade for political reform and fiscal conservatism made him an icon for American conservatives of the time. Cleveland also won praise for honesty, self-reliance, integrity, and commitment to classical liberalism. His fight against political corruption, patronage, and bossism convinced many like-minded Republicans, called "Mugwumps", to cross party lines and support him despite a sexual assault scandal involving a child he fathered. During his first presidency, Cleveland signed the Interstate Commerce Act of 1887, which made the railroad industry the first industry subject to federal regulation by a regulatory body, and the Dawes Act, which subdivided Native American tribal communal landholdings into individual allotments. This policy led to Native Americans ceding control of about two-thirds of their land between 1887 and 1934. In the 1888 election, Cleveland won the popular vote but lost the electoral college and therefore the election to Benjamin Harrison. He returned to New York City and joined a law firm. In a rematch against Harrison for the 1892 election, Cleveland won both the popular vote and electoral college, returning him to the White House. One month before his second presidency began, the Panic of 1893 sparked a severe national depression. An anti-imperialist, Cleveland opposed the push to annex Hawaii, launched an investigation into the 1893 coup against Queen Liliʻuokalani, and called for her restoration. Cleveland intervened in the 1894 Pullman Strike to keep the railroads moving, angering Illinois Democrats and labor unions nationwide; his support of the gold standard and opposition to free silver alienated the agrarian wing of the Democrats. Critics complained that Cleveland had little imagination and seemed overwhelmed by the nation's economic disasters—depressions and strikes—in his second term. Many voters blamed the Democrats, opening the way for a Republican landslide in 1894 and for the agrarian and free silver (silverite) seizure of the Democratic Party at the 1896 Democratic convention. By the end of his second term, he was highly unpopular, even among Democrats. After leaving the White House, Cleveland served as a trustee of Princeton University. He joined the American Anti-Imperialist League in protest of the 1898 Spanish–American War. He died in 1908.

Giuseppe Fortunino Francesco Verdi was an Italian composer best known for his operas. He was born near Busseto, a small town in the modern province of Parma, to a family of moderate means, receiving a musical education with the help of a local patron named Antonio Barezzi.

William George Morgan (January 23, 1870 – December 27, 1942) was an American sports educator and the inventor of volleyball, originally called "Mintonette", a name derived from the game of badminton which he later agreed to change to better reflect the nature of the sport. He was born in Lockport, New York, U.S. He met James Naismith, inventor of basketball, while Morgan was studying at Springfield College in 1892. Like Naismith, Morgan pursued a career in Physical Education at the YMCA. Influenced by Naismith and basketball, in 1895, in Holyoke, Massachusetts, Morgan invented "Mintonette" a less vigorous team sport more suitable for older members of the YMCA but one that still required athletic skill. Later Alfred S. Halstead watched it being played and renamed it "Volleyball". In 1985, he was inducted into the Volleyball Hall of Fame as the inaugural member.

The Davis Cup is the premier international team event in men's tennis. It is organised by World Tennis and contested annually between teams from over 150 competing countries, making it the world's largest annual team sporting competition. It is described by the organisers as the "World Cup of Tennis" and the winners are referred to as the world champions. The competition began in 1900 as a challenge between Great Britain and the United States. Initially titled the International Lawn Tennis Challenge, it soon became known metonymically after the trophy donated by Dwight F. Davis; the name was officially changed after Davis' death in 1945. By 2023, 155 nations entered teams into the competition. The most successful country over the history of the competition is the United States (winning 32 titles and finishing as runners-up 29 times). The most recent champions are Italy, who beat Spain to win their fourth title (and third consecutive one) in 2025. The women's equivalent of the Davis Cup is the Billie Jean King Cup, formerly known as the Federation Cup (1963–1995) and Fed Cup (1995–2020). Australia, Italy, Russia, the Czech Republic and the United States are the only countries to have won both Davis Cup and Federation/Fed/Billie Jean King Cup titles in the same year. The Davis Cup allowed only amateurs and national registered professional players (from 1968) to compete until 1973, five years after the start of the Open Era.

The Russo-Japanese War (8 February 1904 – 5 September 1905) was fought between the Russian Empire and the Empire of Japan over rival imperial ambitions in Manchuria and the Korean Empire. The major land battles of the war were fought on the Liaodong Peninsula and near Mukden in Southern Manchuria, with naval battles taking place in the Yellow Sea and the Sea of Japan. At the end of the First Sino-Japanese War, the Treaty of Shimonoseki of 1895 had ceded the Liaodong Peninsula and Port Arthur to Japan before the Triple Intervention, in which Russia, Germany, and France forced Japan to relinquish its claim. Japan feared that Russia would impede its plans to establish a sphere of influence in mainland Asia, especially as Russia built the Trans-Siberian Railroad, began making inroads in Korea, and acquired a lease of the Liaodong Peninsula and Port Arthur from China in 1898. Japan signed the Anglo-Japanese Alliance in 1902, and began offering to recognize Russia's dominance in Manchuria in exchange for recognition of Korea as part of Japan's sphere of influence. However, this was rejected by Russia. After negotiations broke down, Japan opened hostilities in a surprise attack on the Russian Pacific Fleet at Port Arthur on 9 February [O.S. 27 January] 1904. Both sides declared war, and Japanese troops landed in Korea, crossed the Yalu River into Manchuria in May, and landed more forces on the Liaodong Peninsula. In August, the Japanese laid siege to Port Arthur, which eventually fell in January 1905. In March 1905, Japanese troops took Mukden, the Manchurian capital, after heavy fighting. The Russian Baltic Fleet, which had sailed over seven months and 18,000 nautical miles (33,000 km) from the Baltic Sea to reinforce its Pacific Fleet, arrived in the region in May and was intercepted and destroyed by the Japanese Combined Fleet at the Battle of Tsushima. The war was concluded with the Treaty of Portsmouth (5 September [O.S. 23 August] 1905), mediated by US president Theodore Roosevelt. The treaty recognized Japanese interests in Korea, and awarded to Japan Russia's lease on the Liaodong Peninsula, control of the Russian-built South Manchuria Railway, and the southern half of the island of Sakhalin (Karafuto). The complete military victory of an Asian and non-Western nation over a European and Western power surprised international observers, and transformed the global balance of power, with the Empire of Japan emerging as a great power and the Russian Empire declining in prestige among the European powers. Russia's incurrence of substantial casualties and losses for a cause which resulted in a humiliating defeat contributed to internal unrest culminating in the 1905 Russian Revolution, during which the Russian autocracy was forced to make concessions. More widely, however, Japan's win effectively damaged the credibility of European dominance across Asia.

The United Procession of Women, or Mud March as it became known, was a peaceful demonstration in London on 9 February 1907 organised by the National Union of Women's Suffrage Societies (NUWSS), in which more than three thousand women marched from Hyde Park Corner to the Strand in support of women's suffrage. Women from all classes participated in the largest public demonstration supporting women's suffrage seen up to that date. It acquired the name "Mud March" from the day's weather; incessant heavy rain left the marchers drenched and mud-spattered. The proponents of women's suffrage were divided between those, known as suffragists, who favoured constitutional methods and those who supported direct action, who became known as suffragettes; the NUWSS were constitutional suffragists. The split between the two factions was formalised in 1903 by Emmeline Pankhurst, who formed the Women's Social and Political Union (WSPU). This organisation held demonstrations, heckled politicians and, from 1905, saw several of its members imprisoned for their increasingly militant actions, which gained press attention and increased support from women. To maintain that momentum and to create support for a new suffrage bill in the House of Commons, the NUWSS and other groups organised the Mud March to coincide with the opening of Parliament. The event attracted much public interest and broadly sympathetic press coverage, but when the bill was presented the following month, it was "talked out" without a vote. While the march failed to influence the immediate parliamentary process, it had a considerable impact on public awareness and on the movement's future tactics. Large peaceful public demonstrations, never previously attempted, became standard features of the suffrage campaign; on 21 June 1908 up to half a million people attended Women's Sunday, a WSPU rally in Hyde Park. The marches showed that the fight for women's suffrage had the support of women in every stratum of society, who despite their social differences were able to unite and work together for a common cause.

A meteor, known colloquially as a shooting star, is a glowing streak of a small body (usually meteoroid) going through Earth's atmosphere, after being heated to incandescence by collisions with air molecules in the upper atmosphere, creating a streak of light via its rapid motion and sometimes also by shedding glowing material in its wake. Meteors typically occur in the mesosphere at altitudes from 76–100 kilometres (47–62 miles). The root word meteor comes from the Greek μετεωρίτης (meteōrítēs), meaning "high in the air". Millions of meteors occur in Earth's atmosphere daily. Most meteoroids that cause meteors are about the size of a grain of sand, i.e. they are usually 1 mm (1⁄25 in) or smaller. Meteoroid sizes can be calculated from their mass and density which, in turn, can be estimated from the observed meteor trajectory in the upper atmosphere. Meteors may occur in showers, which arise when Earth passes through a stream of debris left by a comet, or as "random" or "sporadic" meteors, not associated with a specific stream of space debris. A number of specific meteors have been observed, largely by members of the public and largely by accident, but with enough detail that orbits of the meteoroids producing the meteors have been calculated. The atmospheric velocities of meteors result from the movement of Earth around the Sun at about 30 km/s (67,000 mph; 110,000 km/h), the orbital speeds of meteoroids, and the gravity well of Earth. Meteors become visible between about 75 to 120 km (47 to 75 mi) above Earth. They usually disintegrate at altitudes of 50 to 95 km (31 to 59 mi). Meteors have roughly a fifty percent chance of a daylight (or near daylight) collision with Earth. Most meteors are, however, observed at night, when darkness allows fainter objects to be recognized. For bodies with a size scale larger than 10 cm (4 in) to several meters meteor visibility is due to the atmospheric ram pressure (not friction) that heats the meteoroid so that it glows and creates a shining trail of gases and melted meteoroid particles. The gases include vaporised meteoroid material and atmospheric gases that heat up when the meteoroid passes through the atmosphere. Most meteors glow for about a second.

The Svalbard Treaty (originally the Spitsbergen Treaty) recognises the sovereignty of Norway over the Arctic archipelago of Svalbard, at the time called Spitsbergen. The exercise of sovereignty is, however, subject to certain stipulations, and not all Norwegian law applies. The treaty restricts military uses of the archipelago, but it is not demilitarized. The signatories were given equal rights to engage in commercial activities (mainly coal mining) on the islands. Norway and Russia have exercised this right. Uniquely, the archipelago is an entirely visa-free zone under the terms of the Svalbard Treaty. The treaty was signed on 9 February 1920 and submitted for registration in the League of Nations Treaty Series on 21 October 1920. There were 14 original High Contracting Parties: Denmark, France, Italy, Japan, the Netherlands, Norway, Sweden, the United Kingdom (including Australia, Canada, New Zealand, South Africa, and India), and the United States. Of the original signatories, Japan was the last to ratify the treaty, on 2 April 1925, and the treaty came into force on 14 August 1925. Many additional nations acceded to the treaty after it was ratified by the original signatories, including several before it came into force. As of 2026, there are 49 parties to the treaty.

Brazil, officially the Federative Republic of Brazil, is the largest country in South America. It is also the world's fifth-largest country by area and the seventh-largest by population, with over 214 million people. Brazil is a federation composed of 26 states and a Federal District, which hosts the capital, Brasília. Its most populous city is São Paulo, followed by Rio de Janeiro. Brazil has the largest Lusophone population in the world and is the only Portuguese-speaking country in the Americas, where it is the official language.

The Việt Nam Quốc Dân Đảng, also known as the Vietnamese Nationalist Party and abbreviated VNQDĐ, was a nationalist and democratic socialist political group that sought independence from French colonial rule in Vietnam during the early 20th century. Its origins lie in a group of young Hanoi-based intellectuals who began publishing revolutionary material in the mid-1920s. In 1927, after the publishing house failed because of French harassment and censorship, the VNQDĐ was formed under the leadership of Nguyễn Thái Học. Modelling itself on the Kuomintang of Nationalist China the VNQDĐ gained a small following among northerners, particularly teachers and intellectuals. The party, which was less successful among peasants and industrial workers, was organised in small clandestine cells.

The Balkan Pact, or Balkan Entente, was a treaty signed by Greece, Romania, Turkey and Yugoslavia on 9 February 1934 in Athens, aimed at maintaining the geopolitical status quo in the region after the end of World War I. To present a united front against Bulgarian designs on their territories, the signatories agreed to suspend all disputed territorial claims against one another and their immediate neighbours following the aftermath of the war and a rise in various regional irredentist tensions.

World War II, or the Second World War, was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated, with many engaging in total war on an unprecedented scale. World War II was the deadliest conflict in history, causing the deaths of 60 to 75 million people, a majority of whom were civilians. Millions died as a result of massacres, starvation, disease, and genocides including the Holocaust. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.

Daylight saving time (DST), also referred to as daylight savings time, daylight time (United States and Canada), or summer time (United Kingdom, European Union, and others), is the practice of advancing clocks to (in theory) make better use of the longer daylight available during summer by having darkness fall at a later clock time. The typical implementation of DST is to adjust clocks ahead of standard time by one hour in spring or late winter, and to set clocks back by one hour in the autumn (or fall in North American English, hence the mnemonic: "spring forward and fall back"). In many countries, the part of the year when DST is observed is much longer than the part aligned to standard time. The practice of DST was first tested and widely adopted in the early 20th century, since which many countries have abandoned DST partially or entirely.

The Pacific War, sometimes called the Asia–Pacific War or the Pacific Theater, was the theater of World War II fought between Japan and the Allies in East and Southeast Asia, the Pacific and Indian Oceans, and Oceania. It was geographically the largest theater of the war, including the Pacific Ocean theater, the South West Pacific theater, the Second Sino-Japanese War, and the brief Soviet–Japanese War, and included some of the largest naval battles in history. War between Japan and the Republic of China had begun in 1937, with hostilities dating back to Japan's invasion of Manchuria in 1931, but the Pacific War is more widely accepted to have begun in 1941, when the United States and United Kingdom were brought into the war.

The Battle of the Atlantic, the longest continuous military campaign in World War II, ran from 1939 to the defeat of Nazi Germany in 1945, covering a major part of the naval history of World War II. At its core was the Allied naval blockade of Germany, announced the day after the declaration of war, and Germany's subsequent counterblockade. The campaign peaked from mid-1940 to the end of 1943. The Battle of the Atlantic pitted U-boats and other warships of the German Kriegsmarine (navy) and aircraft of the Luftwaffe (air force) against the Royal Navy, Royal Canadian Navy, United States Navy, and Allied merchant shipping. Convoys, coming mainly from North America and predominantly going to the United Kingdom and the Soviet Union, were protected for the most part by the British and Canadian navies and air forces. These forces were aided by ships and aircraft of the United States beginning on 13 September 1941. The Germans were joined by submarines of the Italian Regia Marina (royal navy) after Germany's Axis ally Italy entered the war on 10 June 1940. As an island country, the United Kingdom was highly dependent on imported goods. Britain required more than a million tons of imported material per week in order to survive and fight. The Battle of the Atlantic involved a tonnage war: the Allies struggled to supply Britain while the Axis targeted merchant shipping critical to the British war effort. Rationing in the United Kingdom was also used with the aim of reducing demand, by reducing wastage and increasing domestic production and equality of distribution. From 1942 onwards, the Axis also sought to prevent the build-up of Allied supplies and equipment in the UK in preparation for the invasion of occupied Europe. The defeat of the U-boat threat was a prerequisite for pushing back the Axis in western Europe. The outcome of the battle was a strategic victory for the Allies—the German tonnage war failed—but at great cost: 3,500 merchant ships and 175 warships were sunk in the Atlantic for the loss of 783 U-boats and 47 German surface warships, including 4 battleships (Bismarck, Scharnhorst, Gneisenau, and Tirpitz), 9 cruisers, 7 raiders, and 27 destroyers. This front was the main consumer of the German war effort: Germany spent more money to produce naval vessels than every type of ground vehicle combined, including tanks. The Battle of the Atlantic has been called the "longest, largest, and most complex" naval battle in history. Starting immediately after the European war began, during the Phoney War, the battle lasted for over five years until the German surrender in May 1945. It involved thousands of ships in a theatre covering millions of square miles of ocean. The situation changed constantly, with one side or the other gaining advantage, as participating countries surrendered, joined and even changed sides in the war, and as new weapons, tactics, countermeasures and equipment were developed. The Allies gradually gained the upper hand, overcoming German surface-raiders by the end of 1942 and defeating the U-boats by mid-1943, though losses due to U-boats continued until the war's end. British prime minister Winston Churchill later wrote, "The only thing that really frightened me during the war was the U-boat peril. I was even more anxious about this battle than I had been about the glorious air fight called the 'Battle of Britain'."

The Allies, or Allied powers, formally referred to as the United Nations from 1942, were an international military coalition formed during World War II (1939–1945) to oppose the Axis powers. Its principal members were the "Big Four"—the United Kingdom, the Soviet Union, the United States, and China.

McCarthyism is a political practice defined by the accusation and investigation of left-wing individuals of communist and Soviet influence on American institutions and of Soviet espionage in the United States during the late 1940s through the 1950s, heavily associated with the McCarthy era. After the mid-1950s, U.S. senator Joseph McCarthy, who had spearheaded the campaign, gradually lost his public popularity after several of his accusations were found to be false. The U.S. Supreme Court under Chief Justice Earl Warren made a series of rulings on civil and political rights that overturned several key laws and legislative directives, and helped bring an end to the Second Red Scare.

The Korean War was an armed conflict fought on the Korean Peninsula between North Korea and South Korea and their allies. North Korea was supported by China and the Soviet Union, while South Korea was supported by the United Nations led by the United States under the auspices of the United Nations Command (UNC).

The R-7 Semyorka was a Soviet missile developed during the Cold War, and the world's first intercontinental ballistic missile. The basis for the R-7 rocket family, it was adapted into the world's first orbital launch vehicle, Sputnik, and the crewed orbital launch vehicles Vostok. R-7 derivatives are the most launched rocket family ever with over 2,000 flights as of 2026, primarily Soyuz variants.

The Cavern Club at 10 Mathew Street, in Liverpool was the venue where the Beatles' UK popularity started. John Lennon, Paul McCartney, George Harrison and Pete Best were first seen by Brian Epstein at the club. Epstein eventually became their manager, going on to secure them a record contract. Best was replaced by Ringo Starr on 16 August 1962, which upset many Beatles fans. After taunts of, "Pete forever, Ringo never!", one agitated fan headbutted Harrison in the club.

The Beatles were an English rock band formed in Liverpool in 1960. The band comprised John Lennon, Paul McCartney, George Harrison and Ringo Starr. They are regarded as the most influential band in popular music and were integral to the development of 1960s counterculture and the recognition of popular music as an art form. Rooted in skiffle, beat and 1950s rock 'n' roll, their sound incorporated elements of classical music and traditional pop in innovative ways. They also explored styles ranging from folk and Indian music to psychedelia and hard rock. As pioneers in recording, songwriting and artistic presentation, the Beatles revolutionised many aspects of the music industry and were often publicised as leaders of the era's youth and sociocultural movements.

The Vietnam War was an armed conflict in Vietnam, Laos, and Cambodia fought between North Vietnam and South Vietnam and their allies. North Vietnam was supported by the Soviet Union and China, while South Vietnam was supported by the United States and other anti-communist nations. The conflict was the second of the Indochina wars and a proxy war of the Cold War. The Vietnam War was one of the postcolonial wars of national liberation, a theater in the Cold War, and a civil war, with civil warfare a defining feature from the outset. Direct US military involvement escalated from 1965 until US forces were withdrawn in 1973. The fighting spilled into the Laotian and Cambodian civil wars, which ended with all three countries becoming communist in 1975.

The 1971 San Fernando earthquake occurred in the early morning of February 9 in the foothills of the San Gabriel Mountains in Southern California. The unanticipated thrust earthquake had a magnitude of 6.5 on the Ms scale and 6.6 on the Mw scale, and a maximum Mercalli intensity of XI (Extreme). The event was one in a series that affected Los Angeles County during the late 20th century. Damage was locally severe in the northern San Fernando Valley and surface faulting was extensive to the south of the epicenter in the mountains, as well as urban settings along city streets and neighborhoods. Uplift and other effects affected private homes and businesses.

Leroy Robert "Satchel" Paige was an American professional baseball pitcher who played in Negro league baseball and Major League Baseball (MLB). His career spanned five decades and culminated with his induction into the National Baseball Hall of Fame.

The Apollo program, also known as Project Apollo, was the United States human spaceflight program led by NASA, which landed the first humans on the Moon in 1969. The Apollo program was conceived in 1960 in the Dwight D. Eisenhower presidency during Project Mercury and executed after Project Gemini. The Apollo program was later dedicated to President John F. Kennedy's national goal, "before this decade is out, of landing a man on the Moon and returning him safely to the Earth" in his address to the U.S. Congress on May 25, 1961.

Soyuz 17 was the first of two long-duration missions to the Soviet Union's Salyut 4 space station in 1975. The flight by cosmonauts Aleksei Gubarev and Georgy Grechko set a Soviet mission-duration record of 29 days, surpassing the 23-day record set by the ill-fated Soyuz 11 crew aboard Salyut 1 in 1971.

Aeroflot Flight 3739 was a regularly scheduled Russian domestic flight from Irkutsk to Pulkovo Airport in Saint Petersburg that crashed during takeoff from Irkutsk International Airport on 9 February 1976. Twenty-four of the 114 people on board died in the accident.

The Budd Company was a 20th-century metal fabricator, a major supplier of body components to the automobile industry, and a manufacturer of stainless steel passenger rail cars, airframes, missile and space vehicles, and various defense products.

Japan Air Lines Flight 350 was a domestic scheduled passenger flight from Fukuoka, Fukuoka Prefecture, to Tokyo in Japan. On 9 February 1982, the Douglas DC-8 operating the flight, registered JA8061, crashed into Tokyo Bay on approach to Haneda Airport, resulting in 24 fatalities. Flight 350 was the first crash for Japan Air Lines in the 1980s. The investigation traced the cause of the crash to the deliberate actions of the captain, who was subsequently tried and found not guilty by reason of insanity.

Halley's Comet is the only known short-period comet that is consistently visible to the naked eye from Earth, appearing roughly every 74–79 years. It last appeared in the inner parts of the Solar System in 1986 and will next appear in mid-2061. Officially designated 1P/Halley, it is also commonly called Comet Halley, or sometimes simply Halley.

The February 1987 Palestinian unrest was a wave of unrest across the West Bank and the Gaza strip in February 1987. The wave began on 9 February, with protests breaking out after Israeli soldiers used live ammunition to disperse a demonstration held at the Balata Camp, in the West Bank. The wave continued until late February, escalating into a grenade attack on an Israeli border post and the killing of a Palestinian cab driver who drove into an Israeli military patrol. During the unrest, all five major Palestinian universities were temporarily ordered closed by Israeli authorities.

On 26 December 1991, the Soviet Union was formally dissolved and ceased to exist as a sovereign state and subject of international law. It also brought an end to the Soviet Union's federal government and to Soviet leader Mikhail Gorbachev's efforts to reform the Soviet political and economic system in an attempt to stop a period of political and economic stagnation.

The Provisional Irish Republican Army, officially known as the Irish Republican Army and informally known as the Provos, was an Irish republican paramilitary force that sought to end British rule in Northern Ireland, facilitate Irish reunification and bring about an independent socialist republic, which would encompass all of Ireland. It was the most active republican paramilitary group during the Troubles. It argued that the all-island Irish Republic continued to exist, and it saw itself as that state's army, the sole legitimate successor to the original IRA from the Irish War of Independence. It was designated a terrorist organisation in the United Kingdom and an unlawful organisation in the Republic of Ireland, both of whose authority it rejected.

On 9 February 2001, about nine nautical miles south of Oahu, Hawaii, in the Pacific Ocean, the United States Navy (USN) Los Angeles-class submarine USS Greeneville collided with the Japanese fishery high-school training ship Ehime Maru (えひめ丸) from Ehime Prefecture. In a demonstration for some VIP civilian visitors, Greeneville performed an emergency ballast blow surfacing maneuver. As the submarine shot to the surface, she struck Ehime Maru. Within ten minutes of the collision, Ehime Maru sank. Nine of the thirty-five people aboard were killed: four high school students, two teachers, and three crew members.

On 9 February 2016, two Meridian-branded passenger trains collided head-on at Bad Aibling, Germany. Of approximately 150 people on board the two trains, 12 people died and 85 others were injured, 24 critically.

The 2018 Winter Olympics, officially the XXIII Olympic Winter Games and also known as PyeongChang 2018 (평창2018), was an international winter multi-sport event held between 9 and 25 February 2018 in Pyeongchang County, South Korea, with the opening rounds for certain events held on 8 February, a day before the opening ceremony.

Nayib Armando Bukele Ortez is a Salvadoran politician who has served as the 43rd president of El Salvador since 2019.

The second impeachment trial of Donald Trump, the 45th president of the United States, began on February 9, 2021, and concluded with his acquittal on February 13. Trump had been impeached for the second time by the House of Representatives on January 13, 2021. The House adopted one article of impeachment against Trump: incitement of insurrection. He is the only U.S. president and only federal official to be impeached twice. He was impeached by the House seven days prior to the expiration of his term and the inauguration of Joe Biden. Because he left office before the trial, this was the first impeachment trial of a former president. The article of impeachment addressed Trump's attempts to overturn the 2020 presidential election results and stated that Trump incited the attack on the Capitol in Washington, D.C., while Congress was convened to count the electoral votes and certify the victory of Joe Biden and Kamala Harris.

The Baltic states or the Baltic countries is a geopolitical term encompassing Estonia, Latvia, and Lithuania. All three countries are members of NATO, the European Union, the Eurozone, the Baltic Assembly, and the OECD. The three sovereign states on the eastern coast of the Baltic Sea are sometimes referred to as the "Baltic nations", less often and in historical circumstances also as the "Baltic republics", the "Baltic lands", or simply the Baltics.
