September 5 in History

The Battle of the Frigidus, also called the Battle of the Frigid River, was fought on 5 and 6 September 394 between the armies of the Roman emperor Theodosius the Great and the rebel augustus Eugenius (r. 392–394), in the eastern border of Roman Italy. Theodosius won the battle and defeated the usurpation of Eugenius and Arbogast, restoring unity to the Roman Empire. The battlefield, in the Claustra Alpium Iuliarum near the Julian Alps through which Theodosius's army had passed, was probably in the Vipava Valley – with the Frigidus River being the modern Vipava – or possibly in the valley of the Isonzo. Timasius, the magister militum, commanded the Theodosian army with help from the magister utriusque militiae Stilicho. Arbogast, previously the magister militum under Theodosius's brother-in-law and senior co-emperor Valentinian II (r. 375–392), commanded Eugenius's forces. It was Arbogast who had engineered Eugenius's acclamation after Valentinian's mysterious death. With reinforcements from Theodosius's allies among the Goths led by Alaric and Gainas, and from Bacurius the Iberian, Theodosius's army defeated Eugenius's, and Eugenius was captured and executed. Arbogast killed himself after the battle. The fighting ended the third civil war of Theodosius's reign, after the two fought against Magnus Maximus (r. 383–388). In ecclesiastical history, the battle was remembered as the last to involve an augustus who was a devotee of Roman paganism, though in fact Eugenius was not a pagan. The posthumous accusation of paganism was first levelled by Tyrannius Rufinus to enhance the reputation of Theodosius I, who was a vigorous promoter of Nicene Christianity and the state church of the Roman Empire. Church histories attributed Theodosius's victory at the Frigidus to divine intervention, and Rufinus equated its importance with the Battle of the Milvian Bridge won by Constantine the Great over Maxentius in 312.

The Decretals of Gregory IX, also collectively called the Liber extra, are a source of medieval Catholic canon law. In 1230, Pope Gregory IX ordered his chaplain and confessor, Raymond of Penyafort, a Dominican, to form a new canonical collection destined to replace the Decretum Gratiani, which was the chief collection of legal writings for the church for over 90 years. It has been said that the pope used these letters to emphasize his power over the Universal Church.

Alexander Farnese (Italian: Alessandro Farnese, Spanish: Alejandro Farnesio; 27 August 1545 – 3 December 1592) was an Italian noble and military leader, who was Duke of Parma, Piacenza and Castro from 1586 to 1592, as well as Governor of the Spanish Netherlands from 1578 to 1592. Nephew to King Philip II of Spain, he served in the Battle of Lepanto and the subsequent campaigns of the Holy League against the Ottoman Empire. He was later appointed general of the Spanish army during the Dutch revolt and its ramifications, serving in Netherlands, France and the Holy Roman Empire until his death in 1592. Farnese was regarded by contemporaries and historians as the greatest general of his age, as well as one of the best in history, for his talents as a commander, strategist and diplomat. He held a high leadership over the soldiers and mercenaries of varied nationalities which composed the Spanish tercios, including Spaniards, Italians, Germans and Walloons. His campaigns marked Spain's greatest successes in the Eighty Years' War, giving the Spanish crown permanent control of the southern provinces, in the process establishing the cultural and religious separation which would eventually become the nation of Belgium. During the French Wars of Religion, he decisively relieved Paris for the Catholic League, and also intervened in the Cologne War, granting victory to Ernest of Bavaria. He was slated to direct the land invasion of the British isles in the maligned 1588 Spanish Armada, which failed to embark him and his Army of Flanders. British historian Edward Shepherd Creasy wrote about him: "happy it is for England and the world that this island was saved from becoming an arena for the exhibition of his powers".

Nicolas Fouquet, marquis de Belle-Île, vicomte de Melun et Vaux (French pronunciation: [nikɔla fukɛ]; 27 January 1615 – 23 March 1680) was the Superintendent of Finances in France from 1653 until 1661 under King Louis XIV. He had a glittering career, and acquired enormous wealth. He fell out of favor, accused of peculation (maladministration of the state's funds) and lèse-majesté (disrespect to the monarch). The king had him imprisoned from 1661 until his death in 1680.

The Nine Years' War was a European great power conflict from 1688 to 1697 between France and the Grand Alliance. Fought primarily in Europe, related conflicts include the Williamite war in Ireland, and King William's War in North America. The 1678 Treaty of Nijmegen that ended the Franco-Dutch War was the highpoint of the French expansionist policies pursued by Louis XIV. Over the next few years, he continued attempts to strengthen France's frontiers, culminating in the 1683 to 1684 War of the Reunions. The Truce of Ratisbon guaranteed these new borders for twenty years, but concerns among European Protestant states over French expansion and anti-Protestant policies led to the creation of the Grand Alliance, headed by William of Orange. In September 1688 Louis led an army across the Rhine to seize additional territories beyond it. This move was designed to extend his influence and pressure the Holy Roman Empire into accepting his territorial and dynastic claims. However, Leopold I, Holy Roman Emperor and German princes supported the Dutch in opposing French aims, while the November 1688 Glorious Revolution secured English resources and support for the Alliance. Over the next few years, fighting focused around the Spanish Netherlands, the Rhineland, the Duchy of Savoy, and Catalonia. Although engagements generally favoured Louis' armies, neither side was able to gain a significant advantage, and by 1696 the main belligerents were financially exhausted, making them keen to negotiate a settlement. Under the terms of the 1697 Peace of Ryswick, French control over the entirety of Alsace was officially recognized, but Lorraine and gains on the right bank of the Rhine were relinquished and restored to their rulers. Louis XIV also recognised William III as the rightful king of England, while the Dutch acquired barrier fortresses in the Spanish Netherlands to help secure their borders and were granted a favorable commercial treaty, and Spain regained Luxembourg and other territories from France. However, both sides viewed the peace as only a pause in hostilities, since it failed to resolve who would succeed the ailing and childless Charles II of Spain as ruler of the Spanish Empire, a question that had dominated European politics for over 30 years. This would lead to the War of the Spanish Succession in 1701.

Tsar, also spelled czar, tzar, or csar ( ), is a Slavic title derived from the Latin word caesar. It was intended to mean "emperor" in the European medieval sense of the term—a ruler with the same rank as a Roman emperor, holding it by the approval of another emperor or a supreme ecclesiastical official—but was usually considered by Western Europeans to be equivalent to "king".

Louis XV, known as Louis the Beloved, was King of France from 1 September 1715 until his death in 1774. He succeeded his great-grandfather Louis XIV at the age of five. Until he reached maturity in 1723, the kingdom was ruled by his grand-uncle Philippe II, Duke of Orléans, as Regent of France. Cardinal Fleury was chief minister from 1726 until his death in 1743, at which time the king took sole control of the kingdom.

The First Continental Congress was a meeting of delegates of twelve of the Thirteen Colonies (Georgia did not attend) held from September 5 to October 26, 1774, at Carpenters' Hall in Philadelphia at the beginning of the American Revolution. The meeting was organized by the delegates just after the British Navy implemented a blockade of Boston Harbor and the Parliament of Great Britain passed the punitive Intolerable Acts in response to the Boston Tea Party. During the opening weeks of the Congress, the delegates conducted a spirited discussion about how the colonies could collectively respond to the British government's coercive actions, and they worked to make a common cause. As a prelude to its decisions, the Congress's first action was the adoption of the Suffolk Resolves, a measure drawn up by several counties in Massachusetts that included a declaration of grievances, called for a trade boycott of British goods, and urged each colony to set up and train its own militia. A less radical plan was then proposed to create a Union of Great Britain and the Colonies, but the delegates tabled the measure and later struck it from the record of their proceedings. The First Continental Congress agreed on a Declaration and Resolves that included the Continental Association, a proposal for an embargo on British trade. They also drew up a Petition to the King pleading for redress of their grievances and repeal of the Intolerable Acts. That appeal was unsuccessful, leading delegates from the colonies to convene the Second Continental Congress, also held in Philadelphia, the following May, shortly after the Battles of Lexington and Concord, to organize the defense of the colonies in the American Revolutionary War.

The Battle of the Chesapeake, also known as the Battle of the Virginia Capes or simply the Battle of the Capes, was a fleet action which took place near the mouth of the Chesapeake Bay on 5 September 1781 during the American Revolutionary War. It was fought between a British fleet led by Rear-Admiral of the Red Sir Thomas Graves and a French fleet under Lieutenant général des armées navales François Joseph Paul de Grasse. The strategically decisive battle prevented the Royal Navy from reinforcing or evacuating the besieged British army of Lieutenant-general Lord Cornwallis at Yorktown, Virginia. With its victory, the French navy was able to gain control over local sea lanes and provided the Franco-American besiegers with siege artillery and troops reinforcements. These proved decisive in securing Cornwallis' surrender, which led to British acknowledgement of American independence. De Grasse had the option to attack British forces in either New York or Virginia; he opted for Virginia, arriving at the Chesapeake at the end of August. Graves learned that de Grasse had sailed from the West Indies for North America and that French Admiral de Barras had also sailed from Newport, Rhode Island. He concluded that they were going to join forces at the Chesapeake. He sailed south from Sandy Hook, New Jersey, outside New York Harbor, with 19 ships of the line and arrived at the mouth of the Chesapeake early on 5 September to see de Grasse's fleet already at anchor in the bay. De Grasse hastily prepared most of his fleet for battle—24 ships of the line—and sailed out to meet him. The two-hour engagement took place after hours of maneuvering. The lines of the two fleets did not completely meet; only the forward and center sections fully engaged. The battle was consequently fairly evenly matched, although the British suffered more casualties and ship damage, and it broke off when the sun set. The British tactics have been a subject of debate ever since. The two fleets sailed within view of each other for several days, but de Grasse preferred to lure Graves away from the bay where de Barras was expected to arrive carrying vital siege equipment. He broke away from the British on 13 September and returned to the Chesapeake, where de Barras had since arrived. Graves returned to New York to organize a larger relief effort; this did not sail until 19 October, two days after Cornwallis surrendered. [The] Battle of the Chesapeake was a tactical victory for the French by no clearcut margin, but it was a strategic victory for the French and Americans that sealed the principal outcome of the war.

Olympe de Gouges (French: [ɔlɛ̃p də ɡuʒ] ; born Marie Gouze; 7 May 1748 – 3 November 1793) was a French playwright and political activist. She is best known for her Declaration of the Rights of Woman and of the Female Citizen and other writings on women's rights and abolitionism. Born in southwestern France, de Gouges began her prolific career as a playwright in Paris in the 1780s. A passionate advocate of human rights, she was one of France's earliest public opponents of slavery. Her plays and pamphlets spanned a wide variety of issues including divorce and marriage, children's rights, unemployment and social security. In addition to her being a playwright and political activist, she was also a small time actress prior to the Revolution. De Gouges welcomed the outbreak of the French Revolution but soon became disenchanted when equal rights were not extended to women. In 1791, in response to the 1789 Declaration of the Rights of Man and of the Citizen, de Gouges published her Declaration of the Rights of Woman and of the Female Citizen, in which she challenged the practice of male authority and advocated for equal rights for women. De Gouges was associated with the moderate Girondins and opposed the execution of Louis XVI. Her increasingly vehement writings, which attacked Maximilien Robespierre's radical Montagnards and the Revolutionary government during the Reign of Terror, led to her eventual arrest and execution by guillotine in 1793.

The French Revolution was a period of political and societal change in France that began with the Estates General of 1789 and ended with the Coup of 18 Brumaire on 9 November 1799. Many of the revolution's ideas are considered fundamental principles of liberal democracy, and its values remain central to modern French political discourse. It was caused by a combination of social, political, and economic factors which the existing regime proved unable to manage.

Conscription, also known as the draft in American English and Philippine English, is the practice in which the compulsory enlistment in a national service, mainly a military service, is enforced by law. Conscription dates back to antiquity and it continues in some countries to the present day under various names. The modern system of near-universal national conscription for young men dates to the French Revolution in the 1790s, where it became the basis of a very large and powerful military. Most European nations later copied the system in peacetime, so that men at a certain age would serve 1 to 8 years on active duty and then transfer to the reserve force.

The War of 1812 was a conflict initiated by the United States against the United Kingdom and its allies fought mainly in North America and at sea during the wider Napoleonic Wars. The United States declared war on Britain on 18 June 1812. Although peace terms were agreed upon in the December 1814 Treaty of Ghent, the war did not officially end until the peace treaty was ratified by the United States Senate on 17 February 1815.

Louis XVIII (Louis Stanislas Xavier; 17 November 1755 – 16 September 1824), known as the Desired (French: le Désiré), was King of France from 1814 to 1824, except for a brief interruption during the Hundred Days in 1815. Before his reign, he spent 23 years in exile from France beginning in 1791, during the French Revolution and the First French Empire. Until his accession to the throne of France, he held the title of Count of Provence as brother of King Louis XVI, the last king of the Ancien Régime. On 21 September 1792, the National Convention abolished the monarchy and deposed Louis XVI, who was later executed by guillotine. When his young nephew Louis XVII died in prison in June 1795, the Count of Provence claimed the throne as Louis XVIII. Following the French Revolution and during the Napoleonic era, Louis XVIII lived in exile in Prussia, Great Britain, and Russia. When the Sixth Coalition first defeated Napoleon in 1814, Louis XVIII was placed in what he, and the French royalists, considered his rightful position. However, Napoleon escaped from his exile in Elba and restored the Napoleonic Empire. Louis XVIII fled, and a Seventh Coalition declared war on the French Empire, defeated Napoleon again, and again restored Louis XVIII to the French throne. Louis XVIII ruled as king for slightly less than a decade. His Bourbon Restoration government was a constitutional monarchy, unlike the absolutist Ancien Régime in France before the Revolution. As a constitutional monarch, Louis XVIII's royal prerogative was reduced substantially by the Charter of 1814, France's new constitution. His return in 1815 led to a second wave of White Terror headed by the Ultra-royalist faction. The following year, Louis dissolved the unpopular parliament (the Chambre introuvable), giving rise to the liberal Doctrinaires. His reign was further marked by the formation of the Quintuple Alliance and a military intervention in Spain. Louis had no children, and upon his death the crown passed to his brother, Charles X. Louis XVIII was the last king or emperor of France to die a reigning monarch: his successor, Charles X (r. 1824–1830), abdicated; and both Louis Philippe I (r. 1830–1848) and Napoleon III (r. 1852–1870) were deposed.

Samuel Houston ( , HEW-stən; March 2, 1793 – July 26, 1863) was an American military general and statesman who played a prominent role in the Texas Revolution in which the Republic of Texas seceded from Mexico. He served as the first and third president of the Republic of Texas and then one of the first two United States Senators from Texas after it became a U.S. state. Earlier he served as the sixth governor of Tennessee, and later as the seventh governor of Texas, the only individual to be elected governor of two different U.S. states. Houston was born in Rockbridge County, Virginia to a slave-owning family and would own slaves throughout his life. The family relocated to Maryville, Tennessee, while he was a teenager. Houston ran away from home to live about three years in a Cherokee village, becoming known as "Raven". He served under General Andrew Jackson in the War of 1812, and was appointed as a sub-agent to oversee the removal of the Cherokee from Tennessee into Arkansas Territory in 1818. With the support of Jackson and others, Houston won election to the House of Representatives in 1823. He strongly supported Jackson's presidential candidacies and, in 1827, Houston was elected governor of Tennessee. In 1829, after divorcing his first wife, Houston resigned and moved to the Arkansas Territory to live with the Cherokee again. In 1832, Houston settled in Mexican Texas, amidst rising tensions between U.S. immigrants and the Centralist government of Mexico. After the 1835 Battle of Gonzales, he became prominent in Texas's revolutionary government and the Texian Army, which he led in the decisive 1836 victory at San Jacinto. After the war, Houston won the 1836 Texan presidential election. He left office due to term limits in 1838, but won another term in the 1841 Texas presidential election. Houston supported the U.S. annexation of Texas, which finally took place in 1845. In 1846, he was elected to represent Texas in the U.S. Senate. He joined the Democratic Party and supported President James K. Polk's Mexican–American War, sparked by the annexation and resulting in the Mexican Cession of further vast territory which would become the Southwestern United States. Despite remaining a slave-owner, Houston's Senate record was marked by his unionism and opposition to radicals from both the North and South. He voted for the Compromise of 1850, which settled disputes concerning the lands taken from Mexico, but against the Kansas–Nebraska Act of 1854, which he believed would increase tensions over slavery, later leaving the Democratic Party over the act. He unsuccessfully contested the presidential nomination of the American Party in the 1856 presidential election and of the Constitutional Union Party in the 1860 presidential election. In 1859, Houston was elected governor of Texas. In this role, he opposed Southern secession, and unsuccessfully sought to keep Texas out of the Confederate States of America at the start of the U.S. Civil War. He was the only Southern governor who refused an oath of allegiance to the Confederacy when states started seceding and was forced out of office in 1861. Houston died at his Huntsville home three weeks after the [Battle of Gettysburg]. His name has been honored in numerous ways, and he is the eponym of Houston, the fourth-most-populous city in the United States.

The First Opium War (Chinese: 第一次鴉片戰爭; pinyin: Dìyīcì yāpiàn zhànzhēng), also known as the Anglo-Chinese War, was a series of military engagements fought between the British Empire and Qing China between 1839 and 1842. The immediate issue was the Chinese enforcement of their ban on the opium trade by seizing private opium stocks from mainly British merchants at Guangzhou (then named Canton) and threatening to impose the death penalty for future offenders. Despite the opium ban, the British government supported the merchants' demand for compensation for seized goods, and insisted on the principles of free trade and equal diplomatic recognition with China. Opium was Britain's single most profitable commodity trade of the 19th century. After months of tensions between the two states, the Royal Navy launched an expedition in June 1840, which ultimately defeated the Chinese using technologically superior ships and weapons by August 1842. The British then imposed the "Treaty of Nanking", which forced China to increase foreign trade, give compensation, and cede Hong Kong Island to the British. Following the Second Battle of Chuenpi on 7 January 1841, the British forces occupied Hong Kong, formally raising the Union Jack on 26 January 1841. Consequently, the opium trade continued in China. Twentieth-century nationalists considered 1839 the start of a century of humiliation, and many historians consider it the beginning of modern Chinese history. This initiated over 156 years of British colonial rule of Hong Kong, formalized by the Treaty of Nanking on 29 August 1842 and later expansions, which concluded with the handover of sovereignty back to China on 1 July 1997, following the 1984 Joint Declaration. Senior government officials within the country had been shown to be colluding against the imperial ban due to stocks of opium in European warehouses in clear view being ignored. In 1839, the Daoguang Emperor, rejecting proposals to legalise and tax opium, appointed Viceroy of Huguang Lin Zexu to go to Guangzhou to halt the opium trade completely. Lin wrote an open letter to Queen Victoria appealing to her moral responsibility to stop the opium trade, although she never received it. Lin then resorted to using force in the western merchants' enclave. He arrived in Guangzhou at the end of January 1839 and organized a coastal defence. In March 1839, British opium dealers were forced to hand over 1,420 tonnes (3.1 million lb) of opium. On 3 June 1839, Lin ordered the opium to be destroyed in public on Humen Beach to show the Government's determination to ban smoking. All other supplies were confiscated and a blockade of foreign ships on the Pearl River was ordered. Tensions escalated in July 1839 after drunk British sailors killed a Chinese villager named Lin Weixi; the British official in charge, Admiral Charles Elliot, refused to hand over those accused to Chinese authorities in an attempt to avoid their being killed on the spot, as had happened with British citizens in the Lady Hughes Affair of 1784. Later, fighting broke out, with the British navy destroying the Chinese naval blockade, and launching an offensive. In the ensuing conflict, the Royal Navy used its superior naval and gunnery power to inflict a series of decisive defeats on the Chinese Empire. In 1842, China was forced to sign the Treaty of Nanking—the first of what the Chinese later called the unequal treaties—which granted an indemnity and extraterritoriality to British subjects in China, opened five treaty ports to British merchants, and ceded Hong Kong Island to the British Empire in perpetuity. The failure of the treaty to satisfy British goals of improved trade and diplomatic relations led to the Second Opium War (1856–1860). The resulting social unrest was the background for the Taiping Rebellion, which further weakened the Qing regime.

The American Civil War was a civil war in the United States between the Union and the Confederacy, 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.

The American Indian Wars, also known as the American Frontier Wars, and the Indian Wars, were initially fought by European colonial empires, the United States, and briefly the Confederate States of America and Republic of Texas against various American Indian tribes in North America. These conflicts occurred from the time of the earliest colonial settlements in the 17th century until the end of the 19th century. The various conflicts resulted from a wide variety of factors, the most common being the desire of settlers and governments for tribal lands. The European powers and their colonies enlisted allied Indian tribes to help them conduct warfare against each other's colonial settlements. After the American Revolution, many conflicts were local to specific states or regions and frequently involved disputes over land use; many involved retaliatory violence. As American settlement expanded westward after the American Revolution, conflicts between the United States and Native American nations increased in scale and frequency. A major turning point came during the War of 1812, when Native confederacies in the Old Northwest and the Southern United States allied with the British against the United States. Following the war, armed resistance continued in some regions, but relations between the United States and Native nations were increasingly governed through treaties that transferred large areas of Indigenous land to the United States. Historians have noted that the United States frequently failed to uphold treaty obligations, contributing to recurring disputes and further conflict. The Indian Removal Act of 1830 authorized the president to negotiate treaties exchanging Native American lands east of the Mississippi River for lands in the west. Although the act itself provided for negotiated removals, federal and state authorities subsequently used a combination of treaties, political pressure, and coercion to relocate many Native nations from the southeastern United States to Indian Territory. The resulting removals, including the Trail of Tears, transferred millions of acres of Indigenous land to the United States and opened much of the Southeast to American settlement. As American settlement expanded across the Great Plains and the Western United States, the federal government increasingly confined Native peoples to Indian reservations through treaties, military campaigns, and congressional legislation. Native American tribes and confederacies often achieved significant military victories against American settlers and soldiers, but generally lacked the population, resources, and logistical capacity to sustain prolonged resistance against the expanding United States. Some scholars have characterized aspects of United States policies toward Native Americans, including forced removals, warfare, and reservation policies, as constituting genocide against Native Americans. Other scholars dispute the application of the term genocide to the American Indian Wars as a whole, arguing that the conflicts varied significantly across time and place.

Labor Day is a federal holiday in the United States celebrated on the first Monday of September to honor and recognize the American labor movement and the works and contributions of laborers to the development and achievements in the United States.

On 5 September 1887, a fire broke out in the backstage area of the Theatre Royal in Exeter, England, during the production of The Romany Rye. The fire caused panic throughout the theatre, with 186 people dying from a combination of the direct effects of smoke and flame, crushing and trampling, and trauma injuries from falling or jumping from the roof and balconies. The death toll makes it the worst theatre disaster, the worst single-building fire, and the third worst fire-related disaster in UK history. Most of the dead were in the gallery of the theatre, which had only a single exit with several design flaws, and quickly became clogged with people trying to escape.

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.

World War I, or the First World War, also known as the Great War, was a global conflict between two coalitions: the Allies and the Central Powers. One of the deadliest conflicts in history, World War I resulted in an estimated 15 to 22 million deaths, including those in war crimes and genocides. The war also contributed to the spread of the Spanish flu pandemic. The conflict saw important developments in weaponry, including the first large-scale use of machine guns, artillery, aircraft, chemical weapons, and tanks.

The Zimmerwald Conference, held in Zimmerwald, Switzerland, from September 5 to 8, 1915, was the first of three international conferences convened by anti-militarist socialists in response to the outbreak of World War I and the resulting virtual collapse of the Second International. Those participating in this and later conferences at Kienthal and Stockholm are known as the Zimmerwald movement. The Zimmerwald Conference began the final unraveling of the coalition within the Second International between revolutionary socialists, known as the "Zimmerwald Left" supporting Vladimir Lenin's line, and reformist socialists. The conference issued a manifesto which denounced the war, blaming it on reactionary capitalist governments, and called for working-class unity and for a peace without annexations or reparations. It also established the International Socialist Commission to work for an end to the hostilities. Lenin opposed the majority, criticizing the adoption of peace as the overriding goal. He instead argued for the fighting to be transformed into socialist revolutions, and for the foundation of a new international, which was realized in the Russian October Revolution of 1917 and in the Comintern, founded 1919.

Upper Volta (French: Haute-Volta) was a colony of French West Africa established in 1919 in the territory occupied by present-day Burkina Faso. It was formed from territories that had been part of the colonies of Upper Senegal and Niger and the Côte d'Ivoire. The colony was dissolved on 5 September 1932, with parts being administered by the Côte d'Ivoire, French Sudan and the Colony of Niger. After World War II, on 4 September 1947, the colony was revived as a part of the French Union, with its previous boundaries. On 11 December 1958, it was reconstituted as the self-governing Republic of Upper Volta within the French Community, and two years later on 5 August 1960, it attained full independence. On 4 August 1984, the name was changed to Burkina Faso. The name Upper Volta indicates that the country contains the upper part of the Volta River. The river is divided into three parts, called the Black Volta, White Volta and Red Volta.

The Spanish Civil War was fought in Spain from 1936 to 1939 between the Republicans and the Nationalist rebels. Republicans loyal to the left-leaning Popular Front government of the Second Spanish Republic included socialists, anarchists, communists, and separatists, supported by the Soviet Union. The opposing Nationalists were an alliance of Falangists, monarchists, conservatives, and traditionalists, who established the military-led Spanish State and were directly aided by an intervention from Fascist Italy and participation of Nazi Germany. Due to the international political climate at the time, the war was variously viewed as class struggle, religious struggle, or struggle between republican democracy and dictatorship, revolution and counterrevolution, or communism and fascism. The Nationalists won the war in early 1939, and ruled Spain until Franco's death in November 1975.

Chile, officially the Republic of Chile, is a country in the Southern Cone of southwestern South America. It is the southernmost country in the world and the closest to Antarctica, extending along a narrow strip of land between the Andes Mountains and the Pacific Ocean. According to the 2024 census, Chile had an enumerated population of 18.5 million. The country covers a territorial area of 756,102 square kilometers (291,933 sq mi), sharing borders with Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage to the south.
