September 14 in History

Leo IV the Khazar (Greek: Λέων ὁ Χάζαρος, romanized: Léōn ō Khazaros; 25 January 750 – 8 September 780) was Byzantine emperor from 775 to 780 AD. He was born to Emperor Constantine V and Empress Tzitzak in 750. He was elevated to co-emperor in the next year, in 751, and married to Irene of Athens in 769. When Constantine V died in September 775, while campaigning against the Bulgars, Leo IV became senior emperor. In 778 Leo raided Abbasid Syria, decisively defeating the Abbasid army outside of Germanikeia. Leo died on 8 September 780, of tuberculosis. He was succeeded by his underage son Constantine VI, with Irene serving as regent.

Abū Jaʿfar Hārūn ibn Muḥammad ar-Rashīd, or simply Hārūn ibn al-Mahdī (c. 763 or 766 – 24 March 809), famously known as The Hārūn al-Rashīd, was the fifth of the Abbasid caliphs, reigning from September 786 until his death in March 809. His reign is traditionally regarded to be the beginning of the Islamic Golden Age. His epithet al-Rashid translates to "the Just", "the Upright", or "the Rightly-Guided". Harun established the legendary library Bayt al-Hikma ("House of Wisdom") in Baghdad in present-day Iraq, and during his rule Baghdad began to flourish as a world center of knowledge, culture and trade. During his rule, the family of Barmakids, which played a deciding role in establishing the Abbasid Caliphate, declined gradually. In 796, he moved his court and government to Raqqa in present-day Syria. Domestically, Harun pursued policies similar to those of his father Al-Mahdi. He released many of the Umayyads and Alids his brother Al-Hadi had imprisoned and declared amnesty for all political groups of the Quraysh. Large scale hostilities broke out with Byzantium, and under his rule, the Abbasid Empire reached its peak. A Frankish mission came to offer Harun friendship in 799. Harun sent various presents with the emissaries on their return to Charlemagne's court, including a clock that Charlemagne and his retinue deemed to be a conjuration because of the sounds it emanated and the tricks it displayed every time an hour ticked. Portions of the fictional One Thousand and One Nights are set in Harun's court and some of its stories involve Harun himself. Harun's life and court have been the subject of many other tales, both factual and fictitious.

Roger of Salerno was regent of the Principality of Antioch from 1112 to 1119. He acquired the regency on the death of his predecessor, Tancred, as the actual prince, Bohemond II, was still a child. Although his power was conditional on Bohemond ever arriving in Antioch to rule, he adopted the title prince during his lifetime, and was referred to as such by most chroniclers. There seems to have been a party in Antioch that sought Bohemond's accession instead.

Matilda of Boulogne (c. 1105 – 3 May 1152) was the countess of Boulogne in her own right from 1125 and queen of England as the wife of King Stephen from 1135 until her death. She supported Stephen in his struggle for the English throne against their mutual cousin Empress Matilda, a period known as the Anarchy. Historians attribute Stephen's continued hold on the throne to her courage and determination. Matilda was the daughter of Count Eustace III of Boulogne, from whom she inherited the French County of Boulogne as well as vast estates in England. Her maternal uncle King Henry I of England arranged for her to marry his nephew Stephen of Blois. Henry had intended to be succeeded by his daughter Empress Matilda, but when he died in 1135, Stephen took the throne. Matilda of Boulogne was consequently crowned queen in 1136. Civil war broke out in 1138 when Earl Robert of Gloucester declared for his half-sister Empress Matilda, renouncing his allegiance to King Stephen. Queen Matilda joined her husband in an attempt to quell the rebellion, leading a successful siege of Dover. The conflict intensified in 1139 when Empress Matilda arrived in England to press her claim. Queen Matilda's initial role in the war was primarily that of a diplomat: she brokered peace with her uncle King David I of Scotland and concluded an alliance with King Louis VII of France. After Stephen's capture at the battle of Lincoln in 1141, Matilda took up the leadership of their faction and began assembling an army. Despite her efforts, the kingdom's clergy recognized the empress as ruler. The empress established herself in London and was on the verge of victory when the queen allied with dissatisfied citizenry and led her army to retake the capital. The queen soon besieged the empress in Winchester and, in the subsequent rout, captured Robert of Gloucester, crippling the empress's war effort. By the end of 1141, she had traded Robert for Stephen. Matilda continued to advise Stephen and take part in his government, and came to involve herself closely with church affairs. She patronized a variety of religious orders and founded the abbeys of Coggeshall, Faversham, and Lillechurch, as well as Cressing Temple, Temple Cowley and the hospital of St Katharine's by the Tower. She probably pushed Stephen to secure the succession of their son Eustace; after she died, Stephen recognized the empress's son Henry as his heir, ending the Anarchy.

The Genpei War (源平合戦, Genpei Kassen, Genpei-Gassen; 1180–1185) was a national civil war between the Taira and Minamoto clans during the late Heian period of Japan. It resulted in the downfall of the Taira and the establishment of the Kamakura shogunate under Minamoto no Yoritomo, who appointed himself as Shōgun in 1192, governing Japan as a military dictator from the eastern city of Kamakura. It followed a coup d'état by the Taira in 1179 with the removal of rivals from all government posts, and subsequently banishing them, and a call to arms against the Taira, led by the Minamoto in 1180. The ensuing Battle of Uji took place just outside Kyoto, starting a five-year-long war, concluding with a decisive Minamoto victory in the naval Battle of Dan-no-ura. However, it has been pointed out that the Battle of Ōshū in 1189 was the last battle during this period of civil war, as it completed Yoritomo's nationwide domination through the annexation of Northeast Japan. The name "Genpei" (Japanese pronunciation: [ɡem.pei, -peː], sometimes romanized as Gempei) comes from alternate readings of the kanji "Minamoto" (源 Gen) and "Taira" (平 Hei, pronounced as the second element in some compounds as -pei). The conflict is also known in Japanese as the Jishō–Juei War (治承・寿永の乱, Jishō–Juei no Ran), after the two Imperial eras between which it took place. The term Genpei Kassen is sometimes used in Japan, but it has been argued that it is not appropriate to use the term "Genpei" for this war.

Maria of Montferrat (French: Marie; 1192–1212), known as la Marquise, was the queen of Jerusalem who reigned from 1205 until 1212. She was the eldest daughter of Queen Isabella I and was born posthumously to Isabella's second husband, Marquis Conrad of Montferrat. She succeeded her mother as a minor under the regency of her half-uncle John of Ibelin. A search for a husband who would rule in her name began immediately, but an initial attempt to arrange a marriage with King Peter II of Aragon failed. In 1210, Maria married John of Brienne, who had been selected for her, and was crowned alongside him. John of Brienne took over the government from John of Ibelin and Maria consented to his acts as king. She died shortly after giving birth to her only child, Isabella II, who succeeded her as queen under King John's guardianship.

The Catholic Church, also called the Roman Catholic Church, is the largest Christian church, with an estimated 1.28 to 1.41 billion baptized members worldwide as of 2026. It consists of 24 autonomous churches. The largest one of these churches is the Latin Church. Besides it, there are 23 smaller Eastern Catholic Churches. Together, the Latin Church and Eastern Catholic churches are organized into nearly 3,500 dioceses and eparchies governed by bishops. Throughout history, the church has had a large role in the development of Western civilization. Catholic communities are present worldwide through missions, immigration, and conversions. The majority of Catholics live in the Global South, reflecting rapid demographic growth in Africa, Asia, and Latin America, as well as secularization in parts of Europe and North America.

The Battle of Holmedon Hill or Battle of Homildon Hill was a conflict between English and Scottish armies on 14 September 1402 in Northumberland, England. The battle was recounted in William Shakespeare's Henry IV, Part 1. Although Humbleton Hill is the modern name of the site, over the centuries it has been variously named Homildon, Hameldun, Holmedon, and Homilheugh.

The Bishop Gore School (Welsh: Ysgol Esgob Gore) is a secondary school in Swansea in Wales, founded on 14 September 1682 by Hugh Gore (1613–1691), Bishop of Waterford and Lismore. It is situated in Sketty, close to Singleton Park and Swansea University. In December 2013 the school was ranked in the second highest of five bands by the Welsh Government, based on performance in exams, value added performance, disadvantaged pupils' performance, and attendance.

The Morean war, also known as the Sixth Ottoman–Venetian War, was fought between 1684–1699 as part of the wider conflict known as the "Great Turkish War", between the Republic of Venice and the Ottoman Empire. Military operations ranged from Dalmatia to the Aegean Sea, but the war's major campaign was the Venetian conquest of the Morea (Peloponnese) peninsula in southern Greece.

António Manoel de Vilhena (28 May 1663 – 10 December 1736) was a Portuguese nobleman who was the 66th Prince and Grand Master of the Order of St. John of Jerusalem from 19 June 1722 to his death in 1736. Unlike a number of the other Grand Masters, he was benevolent and popular with the Maltese people. Vilhena is mostly remembered for the founding of Floriana, the construction of Fort Manoel and the Manoel Theatre, and the renovation of the city of Mdina.

George Frideric Handel was a German-British Baroque composer well-known for his operas, oratorios, anthems, concerti grossi, and organ concerti.

The adoption of the Gregorian Calendar has taken place in the history of most cultures and societies around the world, marking a change from one of various traditional dating systems to the contemporary system – the Gregorian Calendar – which is widely used around the world today. Some polities adopted the new calendar in 1582, others not before the early twentieth century, and others at various dates between. A few have yet to do so, but except for these, the Gregorian Calendar is now the universal civil calendar, yet old style calendars remain in use in religious or traditional contexts. During – and for some time after – the transition between systems, it has been common to use the terms "Old Style" and "New Style" in dating to indicate which calendar was used to reckon them.

The Seneca are a group of Indigenous Iroquoian-speaking people who historically lived south of Lake Ontario, one of the five Great Lakes in North America. Their nation was the farthest to the west within the Six Nations or Haudenosaunee in New York before the American Revolution. For this reason, they are called "The Keepers of the Western Door".

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.

The Papal States, officially the State of the Church, were a conglomeration of territories on the Italian Peninsula under the direct sovereign rule of the pope from 756 to 1870. They were among the major Italian states from the 8th century until the unification of Italy, which took place between 1859 and 1870, culminating in their incorporation into the Kingdom of Italy.

The Finnish War was fought between the Kingdom of Sweden and the Russian Empire from 21 February 1808 to 17 September 1809 as part of the Napoleonic Wars. As a result of the war, the eastern third of Sweden was established as the autonomous Grand Duchy of Finland within the Russian Empire. Other notable effects were the Swedish parliament's adoption of a new constitution and the establishment of the House of Bernadotte, the new Swedish royal house, in 1818.

The Napoleonic Wars (1803–1815) were a global series of conflicts fought by a fluctuating array of European coalitions against the French First Republic (1803–1804) under the First Consul followed by the First French Empire (1804–1815) under the Emperor of the French, Napoleon. The wars originated in political forces arising from the French Revolution (1789–1799) and French Revolutionary Wars (1792–1802) and produced a period of French domination over continental Europe. The wars are categorised as seven conflicts, five named after the coalitions that fought Napoleon, plus two named for their respective theatres: the War of the Third Coalition, War of the Fourth Coalition, War of the Fifth Coalition, War of the Sixth Coalition, War of the Seventh Coalition, the Peninsular War, and the French invasion of Russia. The first stage of the wars broke out when Britain declared war on France on 18 May 1803. After minor campaigns, Britain allied with Austria, Russia, and minor powers, to form the Third Coalition in April 1805. Napoleon defeated the allied Russo-Austrian armies in the subsequent war which climaxed in French victories at Ulm and at Austerlitz, leading to the dissolution of the Holy Roman Empire and Austria being forced to make peace. Britain and Russia remained at war with France. Concerned about increasing French power, Prussia joined Britain and Russia in the Fourth Coalition, which resumed war in October 1806. Napoleon defeated the Prussians at Jena-Auerstedt and the Russians at Friedland, bringing an uneasy peace to the continent by July 1807, and again leaving Britain as France's sole major enemy. Britain was unable to dispute French dominance on the continent but obtained hegemony over the seas after victories including Trafalgar. Russia used the interim peace to resolve wars with the Ottomans, Swedes, and Iranians. Hoping to isolate and weaken Britain economically through his Continental System, Napoleon launched an invasion of Portugal, the only remaining British ally in continental Europe. After occupying Lisbon in November 1807, and with the bulk of French troops present in Spain, Napoleon seized the opportunity to turn against his former ally, depose the reigning Spanish royal family, and declare his brother as Joseph I the King of Spain in 1808, to the disapproval of the Spanish populace. Spain joined Britain and Portugal, with the three powers engaging France in the Peninsular War. The diversion of French armies to the large new Anglo-Spanish front led to Austria reentering the conflict and forming the Fifth Coalition in April 1809, composed of Austria, Spain, and Britain. Austria won the Battle of Aspern-Essling but was defeated at Wagram, forcing the imposition of a harsh peace in October 1809. Britain, Spain, and Portugal remained at war with France. Concurrently Russia, unwilling to bear the economic consequences of reduced trade, violated the Continental System, prompting Napoleon to launch an invasion in June 1812. The resulting campaign was costly for both sides, but ultimately ended in disaster for France and the near-destruction of Napoleon's Grande Armée. French forces retreated from Russia by December 1812 and began reconstituting their lost strength. Encouraged by the defeat, Austria, Prussia, and several minor powers joined Russia, Britain, and Spain in a Sixth Coalition and began a campaign against France. The Sixth Coalition defeated Napoleon at Leipzig in October 1813. The allies then invaded France on two fronts: the Russians, Austrians, and Prussians invaded France from the east, while the British, Spanish, and Portuguese invaded France from the west. Coalition troops captured Paris in March 1814, forced Napoleon to abdicate in April, exiled him to the island of Elba, and restored power to the Bourbons. Napoleon escaped exile in February 1815 and reassumed control of France for around one hundred days, igniting the eponymous conflict. The allies formed the Seventh Coalition, which defeated him at Waterloo in June 1815 and exiled him to Saint Helena, where he died in 1821. The wars had profound consequences on history. New methods of warfare were introduced, including mass conscription and guerrilla warfare. Politically, the wars greatly influenced Europe through the advancements in civil law brought about by the Napoleonic Code, which was largely retained where it was adopted, and the spread of nationalism and liberalism. Independence movements emerged in Spanish America as a direct consequence of the wars, leading to the decline of the Spanish and Portuguese Empires. France's defeat led to the rise of Britain as the world's foremost naval and economic power, a status it would hold for the remainder of the century. After the end of the Napoleonic Wars, the Congress of Vienna redrew Europe's borders and brought a relative peace to the continent, with no major great power conflicts until the Crimean War in 1853.

The Battle of Baltimore took place between British and American forces on September 12–14, 1814, during the War of 1812. Defending American forces repulsed sea and land invasions off the busy major port city of Baltimore, Maryland, by British forces preventing the United States' third largest city at the time from falling to British forces and ending the British Chesapeake campaign. The British and Americans first met at the Battle of North Point. Though the Americans were tactically defeated and forced to retreat, the battle was a successful delaying action that inflicted significant casualties on the British including the commanding general Robert Ross, halted their advance, and allowed the defenders at Baltimore to prepare for an attack. The resistance of Baltimore's Fort McHenry during bombardment by the Royal Navy inspired Francis Scott Key to compose the poem "Defence of Fort M'Henry", which later became the lyrics for "The Star-Spangled Banner," the national anthem of the United States. Future U.S. president James Buchanan served as a private in the defense of Baltimore.

The Ottoman Empire, also known historically as Turkey or the Turkish Empire, was a state that spanned much of Southeastern Europe, West Asia, and North Africa from the 14th century to the early 20th century, centred in modern-day Turkey. It also controlled parts of southeastern Central Europe between the early 16th and early 18th centuries. The empire emerged from a beylik, or principality, founded in northwestern Anatolia in c. 1299 by the Turkoman tribal leader Osman I. His successors conquered much of Anatolia and expanded into the Balkans by the mid-14th century, transforming their petty kingdom into a transcontinental empire. The Ottomans ended the Byzantine Empire with the conquest of Constantinople in 1453 by Mehmed II. Further conquests by Selim I led the Sultans to adopt the title of caliph. With its capital at Constantinople and control over a significant portion of the Mediterranean Basin, the Ottoman Empire was at the centre of interactions between the Middle East and Europe for six centuries. Ruling over diverse peoples, the empire granted varying levels of autonomy to its many confessional communities, or millets, to manage their own affairs per Islamic law. During the reign of Suleiman the Magnificent in the 16th century, the Ottoman Empire became a global power. Modern academic consensus posits that the empire began to decline after defeat in the Second Siege of Vienna in 1683, but continued to maintain a flexible and strong economy, society and military into much of the 18th century. The Ottoman Empire fell behind technologically from the rest of Europe by the late 18th century as imperial authority fragmented. Further defeats from Austria and Russia culminated in the loss of territory, and with rising nationalism after the French Revolution, a number of new states emerged in the Balkans. Following Mahmud II's reign and the Tanzimat reforms over the course of the 19th century, the Ottoman state became more powerful and organised internally as a new Ottoman identity took hold. In the 1876 revolution, the Ottoman Empire attempted constitutional monarchy, before reverting to an absolute monarchy under Abdul Hamid II, following the Great Eastern Crisis. Over the course of the late 19th century, Ottoman intellectuals known as Young Turks sought to liberalise and rationalise society and politics along Western lines, culminating in the Young Turk Revolution of 1908 led by the Committee of Union and Progress (CUP), which reestablished a constitutional monarchy. However, following the disastrous Balkan Wars, the CUP became increasingly radicalised and embraced Turkish nationalism, leading to a coup d'état in 1913 that established a dictatorship. In the 19th and in the start of 20th centuries, persecution of Muslims during the Ottoman contraction and in the Russian Empire resulted in large-scale loss of life and mass migration into modern-day Turkey from the Balkans, Caucasus, and Crimea. The CUP joined World War I on the side of the Central Powers. It struggled with internal dissent, especially the Arab Revolt, and engaged in genocide against Armenians, Assyrians, and Greeks. In the aftermath of World War I, the victorious Allied Powers occupied and partitioned the Ottoman Empire, which lost its southern territories to the United Kingdom and France. The successful Turkish War of Independence, led by Mustafa Kemal Atatürk against the occupying Allies, led to the end of the Ottoman sultanate in 1922.

Jung Bahadur Rana,, was the Prime Minister of Nepal and the 1st Maharaja of Lamjung and Kaski. He was born Bir Narsingh Kunwar (1817–1877). His mother, Ganesh Kumari, was the daughter of Kaji Nain Singh Thapa, the brother of Mukhtiyar Bhimsen Thapa from the prominent Thapa dynasty of Chhetri clan. During his lifetime, Jung Bahadur eliminated factional fighting at court, removed his family's rivals such as the Pandes and Basnyats, introduced innovations in the bureaucracy and judiciary, and made efforts to modernize Nepal.

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.

William McKinley (January 29, 1843 – September 14, 1901) was the 25th president of the United States, serving from 1897 until his assassination in 1901. A member of the Republican Party, he led a realignment that made Republicans largely dominant in the industrial states and nationwide for decades. McKinley successfully led the U.S. in the Spanish–American War and oversaw a period of American expansionism, with the annexations of Hawaii, Puerto Rico, Guam, the Philippines, and American Samoa. McKinley was the last president to have served in the American Civil War; he was the only one to begin his service as an enlisted man and end it as a brevet major. After the war, he settled in Canton, Ohio, where he practiced law and married Ida Saxton. In 1876, McKinley was elected to Congress, where he became the Republican expert on the protective tariff, believing protectionism would bring prosperity. His 1890 McKinley Tariff was highly controversial and, together with a Democratic Party redistricting aimed at gerrymandering him out of office, led to his defeat in the Democratic landslide of 1890. He was elected governor of Ohio in 1891 and 1893, steering a moderate course between capital and labor interests. McKinley secured the Republican nomination for president in 1896 amid a deep economic depression and defeated his Democratic rival William Jennings Bryan after a front porch campaign in which he advocated "sound money" (the gold standard unless altered by international agreement) and promised that high tariffs would restore prosperity. McKinley's presidency saw rapid economic growth. He rejected free silver in favor of keeping the nation on the gold standard, and raised protective tariffs, signing the Dingley Tariff of 1897 to protect manufacturers and factory workers from foreign competition and securing the passage of the Gold Standard Act of 1900. McKinley's foreign policy emulated the era's overseas imperialism of the great powers in Oceania, Asia, and the Caribbean Sea. The United States annexed the independent Republic of Hawaii in 1898, and it became the Territory of Hawaii in 1900. McKinley hoped to persuade Spain to grant independence to rebellious Cuba without conflict. Still, when negotiations failed, he requested and signed Congress's declaration of war to begin the Spanish–American War of 1898, in which the United States saw a quick and decisive victory. As part of the peace settlement, Spain turned over to the United States its main overseas colonies of Puerto Rico, Guam, and the Philippines, while Cuba was promised independence but remained under American control until 1902, after McKinley's death. In the Philippines, a pro-independence rebellion began; it was eventually suppressed. McKinley acquired what is now American Samoa when his administration partitioned the Samoan Islands with the empires of Britain and Germany in the Tripartite Convention, during a period of warming ties between the UK and US known as the Great Rapprochement. McKinley defeated Bryan again in the 1900 presidential election in a campaign focused on imperialism, protectionism, and free silver. His second term ended early when he was shot on September 6, 1901, by anarchist Leon Czolgosz. McKinley died eight days later and was succeeded by Vice President Theodore Roosevelt, whose popularity overshadowed McKinley's legacy. Historians regard McKinley's 1896 victory as a realigning election in which the political stalemate of the post-Civil War era gave way to the Republican-dominated Fourth Party System, beginning with the Progressive Era. The United States retains control over the major territories McKinley annexed, aside from the Philippines which became independent in 1946. McKinley is generally ranked among the middle tier of presidents.

Pyotr Arkadyevich Stolypin (Russian: Пётр Арка́дьевич Столы́пин, IPA: [pʲɵtr ɐrˈkadʲjɪvʲɪtɕ stɐˈlɨpʲɪn]; 14 April [O.S. 2 April] 1862 – 18 September [O.S. 5 September] 1911) was a Russian statesman who served as the third prime minister and the interior minister of the Russian Empire from 1906 until his assassination in 1911. Known as a reformer of Russian society and the economy, he initiated reforms which were halted by his assassination. Born in Dresden, in the Kingdom of Saxony, to a prominent Russian aristocratic family, Stolypin became involved in government from his early 20s. His successes in public service led to rapid promotions, culminating in his appointment as interior minister under prime minister Ivan Goremykin in April 1906. In July, Goremykin resigned and was succeeded as prime minister by Stolypin. As prime minister, Stolypin initiated major agrarian reforms, known as the Stolypin reform, that granted the right of private land ownership to the peasantry. His tenure was also marked by increased revolutionary unrest, to which he responded with a new system of martial law that allowed for the arrest, speedy trial, and execution of accused offenders. After numerous assassination attempts, Stolypin was fatally shot in September 1911 by revolutionary Dmitrii Bogrov in Kiev. Stolypin was a monarchist and hoped to strengthen the throne by modernizing the rural Russian economy. Modernity and efficiency, rather than democracy, were his goals. He argued that the land question could be resolved and revolution averted only when the peasant commune was abolished and a stable landowning class of peasants, the kulaks, had a stake in the status quo. His successes and failures have been the subject of controversy among scholars, who agree that he was one of the last major statesmen of Imperial Russia with cogent and forceful public reform policies.

HMAS AE1 was an E-class submarine of the Royal Australian Navy (RAN). She was the first submarine to serve in the RAN, and sank with all hands near what is now East New Britain, Papua New Guinea, on 14 September 1914, after less than seven months in service. Search missions attempting to locate the wreck began in 1976. The submarine was found during the 13th search mission near the Duke of York Islands in December 2017.

The Russian Empire was an empire that extended across northern Eurasia from 1721 until the proclamation of the Russian Republic in 1917, forming the final era of Tsarist Russia and the wider Russian monarchy. At its height in the late 19th century, it covered about 22,800,000 km2 (8,800,000 sq mi), roughly one-sixth of the world's landmass, making it the third-largest empire in history, behind only the British and Mongol empires. The 1897 Russian census found a population of 126 million with considerable ethnic, linguistic, religious, and socioeconomic diversity. From the 10th to 17th century, the Russian lands were dominated by a noble class known as the boyars, above whom stood the grand prince and later the tsar, an absolute monarch. The groundwork of the empire was laid by Ivan III (r. 1462–1505), who greatly expanded his domain, established a centralized Russian national state, and secured independence from the Great Horde. His grandson, Ivan IV (r. 1533–1584), was the first Russian monarch to be crowned as tsar in 1547. Between 1550 and 1700, the Russian state grew by an average of 35,000 km2 (14,000 sq mi) per year. Peter the Great transformed the tsardom into an empire, and fought wars that turned Russia into a major European power. He moved the capital from Moscow to the new model city of Saint Petersburg, and led a cultural revolution that introduced a modern, scientific, rationalist, and Western-oriented system. Catherine the Great (r. 1762–1796) presided over further Russian expansion by conquest, colonization, and diplomacy, while continuing Peter's policy of modernization. Alexander I (r. 1801–1825) helped defeat the militaristic ambitions of Napoleon and constituted the Holy Alliance, which aimed to restrain the rise of secularism and liberalism across Europe. Russia further expanded to the west, south, and east, strengthening it as a European power. Its victories in the Russo-Turkish wars were checked by defeat in the Crimean War (1853–1856), leading to a period of reform and conquests in Central Asia instead. Alexander II (r. 1855–1881) initiated major reforms, most notably the 1861 emancipation of all 23 million serfs. The period also saw major developments in literature, music, and the sciences. By the start of the 19th century, Russian territory extended from the Arctic Ocean in the north to the Black Sea in the south, and from the Baltic Sea in the west to Alaska in the east. It colonized Alaska between 1799 and 1867, and in the early-to-mid 19th century briefly maintained outposts in California. The empire also expanded its control over the Caucasus, most of Central Asia, and parts of Northeast Asia. In the late 19th and early 20th centuries, the empire experienced industrial growth and railway construction, though the country remained largely agrarian. Severe famines, such as that of 1891–1892, along with resistance to political reform, led to growing unrest and the rise of revolutionary movements. Following the 1905 Revolution, Nicholas II (r. 1894–1917) authorized the creation of a national parliament, the State Duma, though ultimate power remained with him. Russia entered the First World War in 1914 on the side of the Allies. High casualties, military setbacks, and severe food and fuel shortages in the cities led to widespread discontent with the monarchy. In 1917, mass unrest in Petrograd and army mutinies culminated in the February Revolution, which led to Nicholas II's abdication, the establishment of the Russian Provisional Government, and the proclamation of the Russian Republic. Political instability, continued involvement in the unpopular war, and economic disruption resulted in mass demonstrations against the government in July. The republic was overthrown in the October Revolution by the Bolsheviks, who proclaimed the Russian Soviet Federative Socialist Republic and signed a treaty that ended Russia's involvement in the war, but who nevertheless were opposed by various factions known collectively as the Whites. After emerging victorious in the Russian Civil War, the Bolsheviks established the Soviet Union across most of the Russian territory; Russia was one of four continental European empires to collapse as a result of World War I, along with Germany, Austria–Hungary, and the Ottoman Empire.

Raoul Villain (19 September 1885 – 17 September 1936) was a French nationalist. He is primarily remembered for his assassination of French socialist leader Jean Jaurès on 31 July 1914, in Paris.

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.

The Ip massacre was the mass killing of around 150 ethnic Romanians by the Royal Hungarian Army on 14 September 1940, in Ipp,, Northern Transylvania, and in nearby locations and surrounding areas.

The President of India is the Supreme Commander of the Indian Army, and its professional head is the Chief of the Army Staff (COAS). The Indian Army was established on 1 April 1895 alongside the long established presidency armies of the East India Company, which too were absorbed into it in 1903. Some princely states maintained their own armies which formed the Imperial Service Troops which, along with the Indian Army formed the land component of the Armed Forces of the Crown of India, responsible for the defence of the Indian Empire. The Imperial Service Troops were merged into the Indian Army after independence. The units and regiments of the Indian Army have diverse histories and have participated in several battles and campaigns around the world, earning many battle and theatre honours before and after Independence.

The Totskoye nuclear exercise was a military exercise undertaken by the Soviet Army to explore defensive and offensive warfare during nuclear war. The exercise, under the code name "Snowball", involved an aerial detonation of a 40 kt RDS-4 nuclear bomb. The stated goal of the operation was military training for breaking through heavily fortified defensive lines of a military opponent using nuclear weapons. An army of 45,000 soldiers marched through the area around the hypocenter soon after the nuclear blast. The exercise was conducted on September 14, 1954, at 9.33 a.m., under the command of Marshal Georgy Zhukov to the north of Totskoye village in Orenburg Oblast, Russia, in the South Ural Military District.

A major worldwide financial crisis centered in the United States took place in 2008. The immediate cause of the crisis was the collapse of the 2000s U.S. housing bubble, which involved excessive speculation in property values by both homeowners and financial institutions, exacerbated by predatory lending and by deficiencies in regulation. The first phase was the subprime mortgage crisis, which began in early 2007 as mortgage-backed securities (MBS) tied to U.S. real estate, and a vast web of derivatives linked to those MBS, collapsed in value. A liquidity crisis spread to global institutions by mid-2007 and climaxed with the bankruptcy of Lehman Brothers in September 2008, which triggered a stock market crash and bank runs in several countries. The crisis exacerbated the Great Recession, a global recession that began in late 2007, and contributed to major crises in Iceland and the eurozone.

The first direct observation of gravitational waves was made on 14 September 2015 and was announced by the LIGO and Virgo collaborations on 11 February 2016. Previously, gravitational waves had been inferred only indirectly, via their effect on the timing of pulsars in binary star systems. The waveform, detected by both LIGO observatories, matched the predictions of general relativity for a gravitational wave emanating from the inward spiral and merger of two black holes and the subsequent ringdown of a single, 62 M☉ black hole remnant. The signal was named GW150914. It was also the first observation of a binary black hole merger, demonstrating both the existence of binary stellar-mass black hole systems and the fact that such mergers could occur within the current age of the universe.
