December 11 in History

Emperor Xian of Han (2 April 181 – 21 April 234), personal name Liu Xie (劉協), courtesy name Bohe, was the 14th and last emperor of the Eastern Han dynasty of China. He reigned from 28 September 189 until his abdication and subsequent end of the dynasty on 11 December 220. Liu Xie was a son of Liu Hong (Emperor Ling) and was a younger half-brother of his predecessor, Liu Bian (Emperor Shao). In 189, at the age of eight, he became emperor after the warlord Dong Zhuo, who had seized control of the Han central government, deposed Emperor Shao and replaced him with Liu Xie. The newly enthroned Liu Xie, historically known as Emperor Xian, was in fact a puppet ruler under Dong Zhuo's control. In 190, when a coalition of regional warlords launched a punitive campaign against Dong Zhuo in the name of freeing Emperor Xian, Dong Zhuo ordered the destruction of the imperial capital, Luoyang, and forcefully relocated the imperial capital along with its residents to Chang'an. After Dong Zhuo's assassination in 192, Emperor Xian fell under the control of Li Jue and Guo Si, two former subordinates of Dong Zhuo. The various regional warlords formally acknowledged Emperor Xian's legitimacy but never took action to save him from being held hostage. In 195, Emperor Xian managed to escape from Chang'an and return to the ruins of Luoyang during a feud between Li Jue and Guo Si, where he soon became stranded. A year later, the warlord Cao Cao led his forces into Luoyang, received Emperor Xian, took him under his protection, and escorted him to Xu, where the new imperial capital was established. Although Cao Cao paid nominal allegiance to Emperor Xian, he was actually the de facto head of the central government. He skillfully used Emperor Xian as a "trump card" to bolster his legitimacy when he attacked and eliminated rival warlords in his quest to reunify the Han Empire under the central government's rule. Cao Cao's success seemed inevitable until the winter of 208–209, when he lost the decisive Battle of Red Cliffs against the southern warlords Sun Quan and Liu Bei. The battle paved the way for the subsequent emergence of the Three Kingdoms of Wei, Shu, and Wu. In late 220, some months after Cao Cao's death, Cao Cao's successor, Cao Pi, forced Emperor Xian to abdicate the throne to him. He then established the state of Cao Wei with himself as the new emperor – an event marking the formal end of the Han dynasty and the beginning of the Three Kingdoms period in China. The dethroned Emperor Xian received the noble title Duke of Shanyang (Chinese: 山陽公) from Cao Pi and spent the rest of his life in comfort and enjoyed preferential treatment. He died on 21 April 234, about 14 years after the fall of the Han dynasty.

Julian (Latin: Flavius Claudius Julianus; Ancient Greek: Ἰουλιανός Ioulianos; 331 – 26 June 363) was Caesar of Western Rome from 355 to 360 and Roman emperor from 361 to 363, as well as a notable philosopher and author in Greek. His rejection of Christianity, public conversion to paganism, and promotion of Neoplatonic Hellenism caused him to be remembered as Julian the Apostate in the Christian tradition. A nephew of Constantine the Great, Julian was one of few in the imperial family to survive the purges and civil wars during the reign of Constantius II, his cousin. Julian was orphaned as a child after his father was executed in 337 and spent much of his life under Constantius's close supervision. However, the emperor allowed Julian freedom to pursue an education in the Greek-speaking east. In 355, Constantius II appointed Julian to govern Gaul; his rule was successful, defeating and countering Germanic raids across the Rhine and encouraging the provinces' return to prosperity. In 360, he was proclaimed emperor by his soldiers at Lutetia (Paris), sparking a civil war with Constantius. However, Constantius died before the two could face each other in battle, having named Julian as his successor to prevent further bloodshed. In 363, Julian embarked on an ambitious military expedition against the Sasanian Empire, mustering the largest Roman army to ever face the Persians. The campaign was initially successful, securing a victory outside the capital of Ctesiphon. However, rather than besiege the city, Julian instead moved into Persia's heartland, where he soon faced supply problems and was forced to retreat northwards while being ceaselessly harassed by Persian skirmishers. During the Battle of Samarra, Julian was mortally wounded. He was succeeded by Jovian, a senior officer in the imperial guard, who was obliged to cede territory, including Nisibis, in order to save the trapped Roman forces. Julian and Jovian were the last sole emperors to rule the whole Empire for their entire reign, after which it was permanently divided between a Western and Eastern court. Julian was the last non-Christian ruler of the Roman Empire, and he believed it necessary to restore the Empire's ancient Roman values and traditions in order to save it from dissolution. He purged the top-heavy state bureaucracy, openly promoted pagans to high political offices, and attempted to revive traditional Roman religious practices at the expense of Christianity. His efforts to build a Third Temple in Jerusalem were probably intended to harm Christianity rather than please Jews. Julian also expelled Christians from the military and forbade them from teaching and learning classical texts. Though his reign saw a brief resurgence of paganism in public and political life, his policies ultimately had no lasting effect on its continuing decline.

The Abbasid Caliphate or Abbasid Empire was the third Islamic caliphate, ruled by the Abbasid dynasty. The dynasty was descended from Muhammad's uncle, Abbas ibn Abd al-Muttalib, after whom it is named. The Abbasids rose to power in 750, when the Abbasid Revolution overthrew the preceding Umayyad Caliphate. They ruled as caliphs from their base in Iraq until 1258, with Baghdad as their capital for most of their history.

The foundation of Constantinople in 330 AD marks the conventional start of the Byzantine Empire, which fell to the Ottoman Empire in 1453 AD. Only the emperors who were recognized as legitimate rulers and exercised sovereign authority are included, to the exclusion of junior co-emperors who never attained the status of sole or senior ruler, as well as of the various usurpers or rebels who claimed the imperial title.

Michael V Kalaphates (Ancient Greek: Μιχαήλ Καλαφάτης, Michaḗl Kalaphátēs) was Byzantine emperor for four months in 1041–1042. He was the nephew and successor of Michael IV and the adoptive son of Michael IV's wife Empress Zoe. He was popularly called "the Caulker" (Kalaphates) in accordance with his father's original occupation.

The Treaty of Benavente, signed on 11 December 1230, was the agreement by which Sancha and Dulce, the heiresses of the Kingdom of León, renounced their throne to their brother, King Ferdinand III of Castile, thus uniting the kingdoms of León and Castile into the Crown of Castile.

The Battle of Orewin Bridge (also known as the Battle of Irfon Bridge or the Battle of Builth) was a confrontation between an English force guided by Roger Lestrange and a Welsh force led by Prince Llywelyn ap Gruffudd. It was fought on 11 December 1282 near Builth Wells in mid-Wales. It was a decisive defeat for the Welsh and Llywelyn ap Gruffudd was killed, leading to the final defeat of the Welsh rebels by the armies of Edward I of England some months later. The exact details of the confrontation, including the geographic setting and its scale, are heavily contested, both among contemporary chronicles and later scholars.

The Nyköping Banquet (Swedish: Nyköpings gästabud) was King Birger of Sweden's Christmas celebration 11 December 1317 at Nyköping Castle in Sweden. Among the guests were his two brothers Duke Valdemar and Duke Eric, who later that night were imprisoned and have been assumed to have subsequently starved to death in the dungeon of Nyköping Castle. The principal source to these events is the very biased Eric Chronicle. The author Vilhelm Moberg called it "a Shakespearean episode" in his work Min svenska historia.

Charles Emmanuel I (Italian: Carlo Emanuele di Savoia; 12 January 1562 – 26 July 1630), known as the Great and nicknamed Testa di Fuoco (Piedmontese: Testa d'feu; "Hothead", a sobriquet attributed to his aggressive and rash military character), was the Duke of Savoy and ruler of the Savoyard states from 30 August 1580 until his death on 26 July 1630, nearly 50 years later. At the time of his death, he was the longest-reigning Savoyard monarch, a record later surpassed by his great-grandson Victor Amadeus II. A bold and ambitious ruler, Charles Emmanuel sought to expand Savoyard influence throughout northern Italy during a period marked by the French wars of religion, the Thirty Years' War, and intense rivalry between France and Spain. He led multiple military campaigns – annexing Saluzzo, Trino and Alba but losing Pinerolo and some transalpine territories – and often played European powers against each other in complex diplomatic maneuvers. He was also a patron of the arts and a writer himself. His campaigns against Spanish influence contributed to the emergence of early Italian nationalist sentiment in 17th-century poetry and political discourse.

The Root and Branch Petition was a petition presented to the Long Parliament on 11 December 1640. The petition had been signed by 15,000 Londoners and was presented to the English Parliament by a crowd of 1,500. The petition called on Parliament to abolish episcopacy from the 'roots' and in all its 'branches'.

The Glorious Revolution was the deposition of King James II in November 1688. He was replaced by his daughter Mary II and her Dutch husband, James's nephew William III of Orange. The two ruled as joint monarchs of England, Scotland, and Ireland until Mary's death in 1694, when William became ruler in his own right. Jacobitism, the political movement that aimed to restore the exiled James or his descendants of the House of Stuart to the throne, persisted into the late 18th century. Some historians consider William's invasion the last successful invasion of England. Despite being a Roman Catholic, James had become king in February 1685 with widespread backing from the Protestant majorities in England and Scotland, as well as largely Catholic Ireland, but his policies quickly eroded support. The prospect of a Catholic dynasty following the birth of his son James Francis Edward Stuart on 10 June 1688 led some of his domestic opponents to issue the Invitation to William, seeking Dutch support to remove him. The Dutch States General and William of Orange were concerned that James might support France in the Nine Years' War. Exploiting unrest in England and claiming to be responding to the invitation, William landed with an army in Devon on 5 November 1688. As William advanced on London, James's army disintegrated and he went into exile in France on 23 December. In April 1689, a Convention made William and Mary joint monarchs of England and Ireland. A separate but similar Scottish settlement was made in June 1689. Domestically, the Revolution confirmed the primacy of Parliament over the Crown in both England and Scotland. In terms of external policy, until his death in 1702, William combined the roles of Dutch stadtholder and English and Scottish monarch. Both states thus became allies in resisting French expansion, an alliance which persisted for much of the 18th century, despite differing objectives.

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.

The United States Senate is a chamber of the bicameral United States Congress; it is the upper house, and the U.S. House of Representatives is the lower house. Together, the Senate and House have the authority under Article One of the Constitution to make and pass or defeat federal legislation.

Indiana ( IN-dee-AN-ə) is a state in the Midwestern region of the United States. It borders Lake Michigan to the northwest, Michigan to the north and northeast, Ohio to the east, the Ohio River and Kentucky to the south and southeast, and the Wabash River and Illinois to the west. Nicknamed "the Hoosier State", Indiana is the 38th-largest by area and the 17th-most populous of the 50 states. The state's capital and largest city is Indianapolis. Indiana was admitted to the Union as the 19th state on December 11, 1816. Indigenous resistance to American settlement was broken with their defeat in Battle of Tippecanoe in 1811, and the collapse of Tecumseh's confederacy in 1813. The new settlers were primarily Americans of British ancestry from the eastern seaboard and the Upland South, and Germans. After the Civil War, in which the state fought for the Union, natural gas attracted heavy industry and new European immigrants to its northern counties. In the first half of the 20th century, northern and central sections experienced a boom in goods manufacture and automobile production. Southern Indiana remained largely rural. After the rise and fall of the Klan in the 1920s, the state swung politically from the Republican to Democratic Party in the New Deal 1930s. Today, with a decades-long record of returning Republican majorities, Indiana is counted a "red state". Indiana has a diverse economy with a gross state product in 2023 of 404.3 billion. Indianapolis is at the center of the state's largest metropolitan area, with a population of over two million. The Fort Wayne metro area follows with a population of 645,000. The state's largest city, Indianapolis, is home to professional sports teams, including the NFL's Indianapolis Colts, the NBA's Indiana Pacers, and the WNBA's Indiana Fever. The city also hosts several notable competitive events, such as the Indianapolis 500, held at Indianapolis Motor Speedway.

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.

The Paraguayan War, also known as the War of the Triple Alliance, was a war in South America that lasted from 1864 to 1870. It was fought between Paraguay and the Triple Alliance of Argentina, Brazil and Uruguay. It was the deadliest inter-state war in Latin American history. Paraguay sustained immense casualties, but even the approximate numbers are disputed. Paraguay was forced to cede disputed territory to Argentina and Brazil. The war began in late 1864, as a result of a conflict between Paraguay and Brazil caused by the Uruguayan War. Argentina and Uruguay entered the war against Paraguay in 1865, and it then became known as the "War of the Triple Alliance".

The Second Boer War was a conflict fought between 1899 and 1902 between the British Empire and the Boer republics (the South African Republic and Orange Free State), triggered by the discovery of gold in the Transvaal, specifically the Witwatersrand gold fields, and the ensuing political dispute over the voting rights of British expatriates (Uitlanders). In 1877, the British annexed the bankrupt Transvaal, and the British military neutralized the regional threat of the Zulu Kingdom in 1879 in the Anglo-Zulu War. With their borders secure, the Boers subsequently revolted and regained their independence after defeating the British in the First Boer War (1880–1881). The Witwatersrand Gold Rush caused an influx of "foreigners" (Uitlanders), most of them British from the Cape Colony, to the South African Republic (SAR), an independent Boer Republic. As they were permitted to vote only after 14 years' residence, they protested to the British authorities in the Cape. Negotiations failed at the botched Bloemfontein Conference in June 1899. The conflict broke out in October after the British government decided to send 10,000 troops. The war had three phases. In the first, the Boers mounted preemptive strikes into British-held territory in Natal and the Cape Colony, besieging British garrisons at Ladysmith, Mafeking, and Kimberley. The Boers won victories at Stormberg, Magersfontein, Colenso and Spion Kop. In the second phase, British fortunes changed when their commanding officer, General Redvers Buller, was replaced by Lord Roberts and Lord Kitchener, who relieved the besieged cities and invaded the Boer republics at the head of a 180,000-strong expeditionary force. The Boers, aware that they were unable to resist such a force, refrained from fighting pitched battles, thereby allowing the British to occupy both republics and their capitals. Boer politicians fled or went into hiding; the British annexed the two republics in 1900. In Britain, the Conservative ministry attempted to capitalise by calling an early general election, dubbed a "khaki election". In the third phase, Boer fighters launched a guerrilla campaign. They used hit-and-run attacks and ambushes against the British for two years. The guerrilla campaign proved difficult for the British to defeat, due to unfamiliarity with tactics and support among civilians. British high command ordered scorched earth policies as part of a counterinsurgency campaign. Over 100,000 Boer civilians were forcibly relocated into concentration camps, where 26,000 died, by starvation and disease. Native Africans were interned to prevent them from supplying the Boers; 20,000 died. British mounted infantry were deployed to track down guerrillas, and few combatants were killed in action, most dying from disease. Kitchener offered terms to remaining Boer leaders to end the conflict. Eager to ensure Boers were released from the camps, most Boer commanders accepted the terms in the Treaty of Vereeniging, surrendering in May 1902. The former republics were transformed into the British colonies of the Transvaal and Orange River, and in 1910 were merged with the Natal and Cape Colonies to form the Union of South Africa, a self-governing colony within the British Empire. British expeditionary efforts were aided significantly by colonial forces from the Cape Colony, the Natal, Rhodesia, and many volunteers from the British Empire. Native African recruits contributed increasingly to the British effort. International public opinion was sympathetic to the Boers and hostile to the British. Even within the UK, there existed significant opposition to the war. As a result, the Boer cause attracted volunteers from neutral countries, including the German Empire, the United States, Russia and parts of the British Empire, such as Australia and Ireland. Some consider the war the beginning of questioning the British Empire's global dominance, due to the war's surprising duration and unforeseen losses suffered by the British. A trial for British war crimes, including the killings of civilians and prisoners of war, was opened in January 1902. The war had a lasting effect on the region and on British domestic politics.

Guglielmo Giovanni Maria Marconi, 1st Marquess of Marconi (25 April 1874 – 20 July 1937), was an Italian electrical engineer, inventor, and politician known for his creation of a practical radio wave-based wireless telegraph system. This led to his being largely credited as the inventor of radio and sharing the 1909 Nobel Prize in Physics with Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy." As an entrepreneur and a businessman, Marconi founded The Wireless Telegraph & Signal Company (later the Marconi Company) in the United Kingdom in 1897. In 1929, he was ennobled as a marquess (Italian: marchese) by King Victor Emmanuel III, thus becoming the 1st Marchese di Marconi. In 1931, he set up Vatican Radio for Pope Pius XI.

Kyiv, also spelt Kiev, is the capital and most populous city of Ukraine. Located in the north-central part of the country, it straddles both banks of the Dnieper River. As of January 2022, the population of Kyiv was 2,952,301, making it the seventh-most populous city in Europe. Kyiv is an important industrial, scientific, educational, and cultural center. It is home to high-tech industries, higher education institutions, and historical landmarks. The city has an extensive public transport system, which includes the Kyiv Metro.

The New Zealand Parliament Buildings house the New Zealand Parliament and are on a 45,000 square metre site at the northern end of Lambton Quay, Wellington. From north to south, they are the Parliamentary Library building (1899); the Edwardian neoclassical-style Parliament House (1922); the executive wing, called "The Beehive" (1977); and Bowen House. Currently, an additional building for housing Members of Parliament is under construction, which is expected to be completed in 2027. Whilst most of the individual buildings are outstanding for different reasons, the overall setting that has been achieved "has little aesthetic or architectural coherence".

The Louvre (French: Musée du Louvre [myze dy luvʁ] ) is a national art museum in Paris, France. It is located on the Right Bank of the Seine in the city's 1st arrondissement (district) and home to some of the most canonical works of Western art, including the Mona Lisa, Venus de Milo, and Winged Victory. The museum is housed in the Louvre Palace, originally built in the late 12th to 13th century under Philip II. Remnants of the Medieval Louvre fortress are visible in the basement of the museum. Due to urban expansion, the fortress eventually lost its defensive function, and in 1546 Francis I converted it into the primary residence of the French kings. The building was redesigned and extended many times to form the present Louvre Palace. In 1682, Louis XIV chose the Palace of Versailles for his household, leaving the Louvre primarily as a place to display the royal collection, including, from 1692, a collection of ancient Greek and Roman sculptures. In 1692, the building was occupied by the Académie des Inscriptions et Belles-Lettres and the Académie Royale de Peinture et de Sculpture, which in 1699 held the first of a series of salons. The Académie remained at the Louvre for 100 years. During the French Revolution, the National Assembly decreed that the Louvre should be used as a museum to display the nation's masterpieces. The palace and exhibition space was expanded in the 19th century and again in the 20th. The museum opened on 10 August 1793 with an exhibition of 537 paintings, the majority of the works being royal and confiscated church property. Because of structural problems with the building, the museum was closed from 1796 until 1801. The collection was increased under Napoleon, after the Napoleonic looting of art in Europe, Egypt, and Syria, and the museum was renamed Musée Napoléon, but after Napoleon's abdication, many works seized by his armies were returned to their original owners. The collection was further increased during the reigns of Louis XVIII and Charles X, and during the Second French Empire the museum gained 20,000 pieces. Holdings have grown steadily through donations and bequests since the Third Republic. The collection is divided into eight departments: Egyptian Antiquities; Near Eastern Antiquities; Greek, Etruscan, and Roman Antiquities; Islamic Art; Sculpture; Decorative Arts; Paintings; Prints and Drawings. The Musée du Louvre contains approximately 500,000 objects and displays 35,000 works of art in eight curatorial departments with more than 60,600 m2 (652,000 sq ft) dedicated to the permanent collection. The Louvre exhibits sculptures, objets d'art, paintings, drawings, and archaeological finds. At any given point in time, approximately 38,000 objects from prehistory to the 21st century are being exhibited over an area of 72,735 m2 (782,910 sq ft), making it the largest museum in the world. It received 9.0 million visitors in 2025. It is ranked as the most-visited art museum, and most-visited museum of any category.

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 helped spread 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 Irish War of Independence, also known as the Anglo-Irish War or the Tan War, was a guerrilla war fought in Ireland from 1919 to 1921 between the Irish Republican Army and British forces: the British Army, along with the quasi-military Royal Irish Constabulary (RIC) and its paramilitary forces the Auxiliaries and Ulster Special Constabulary (USC). It was part of the Irish revolutionary period.

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 Guangzhou Uprising, Canton Uprising, or Canton Riots of 1927 was a failed communist uprising in the city of Guangzhou (Canton) in southern China.

The Statute of Westminster 1931 (22 & 23 Geo. 5. c. 4) is an act of the Parliament of the United Kingdom that significantly increased the autonomy of the Dominions of the British Commonwealth. Passed on 11 December 1931, the statute increased the sovereignty of the self-governing Dominions of the British Empire from the United Kingdom. It also bound them all to seek each other's approval for changes to monarchical titles and the common line of succession. The statute was effective either immediately or upon ratification. It thus became a statutory embodiment of the principles of equality and common allegiance to the Crown set out in the Balfour Declaration of 1926. As the statute removed nearly all of the British parliament's authority to legislate for the Dominions, it was a crucial step in the development of the Dominions as separate, independent, and sovereign states. Its modified versions are now domestic law in Australia and Canada (including Newfoundland and Labrador). It is no longer in effect in New Zealand, and has been implicitly repealed in former Dominions that are no longer Commonwealth realms.

William Griffith Wilson (November 26, 1895 – January 24, 1971), also known as Bill Wilson or Bill W., was an American businessman who co-conceived and co-founded Alcoholics Anonymous (AA), with fellow co-founder Bob Smith. AA is an international mutual aid fellowship with about two million members worldwide belonging to AA groups, associations, organizations, cooperatives, and fellowships of alcoholics helping other alcoholics achieve and maintain sobriety. Following AA's Twelfth Tradition of anonymity, within the organization Wilson is commonly known as "Bill W." or "Bill". After his death, with his prior written permission, his full name was included in obituaries. Wilson's sobriety from alcohol, which he maintained until his death, began December 11, 1934. In 1955, he turned over control of AA to a board of trustees. He died in 1971, and in 1999 Time listed him as "Bill W.: The Healer" in the Time 100: The Most Important People of the Century.

In early December 1936, a constitutional crisis in the British Empire arose when King Edward VIII proposed to marry Wallis Simpson, an American socialite who was divorced from her first husband and was in the process of divorcing her second. The marriage was opposed by the governments of the United Kingdom and the Dominions of the British Commonwealth. Religious, legal, political, and moral objections were raised. As the British monarch, Edward was Supreme Governor of the Church of England, which at this time did not allow divorced people to remarry in church if their ex-spouses were still alive. For this reason, it was widely believed that Edward could not marry Wallis and remain on the throne. As a double-divorcée, Wallis was perceived to be politically, morally and socially unsuitable as a prospective queen consort. It was widely assumed by the Establishment that she was driven by love of money or position rather than love for the King. Despite the opposition, Edward declared that he loved Wallis and intended to marry her as soon as her second divorce was finalised. The widespread unwillingness to accept Wallis as the King's consort and Edward's refusal to give her up led to his abdication in December 1936. He was succeeded by his brother Albert, who became George VI. Edward was given the title of Duke of Windsor, and styled Royal Highness, following his abdication, and he married Wallis the following year. They remained married until his death 35 years later.

The Second Italo-Ethiopian War, also referred to as the Second Italo-Abyssinian War, was a war of aggression waged by Italy against Ethiopia, which lasted from October 1935 to May 1936. In Ethiopia it is often referred to simply as the Italian Invasion, and in Italy as the Ethiopian War. The war is regarded as the largest colonial campaign in history.

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.

Superfund is a United States federal environmental remediation program established by the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). The program is administered by the Environmental Protection Agency (EPA) and is designed to pay for investigating and cleaning up sites contaminated with hazardous substances. Sites managed under this program are referred to as Superfund sites. The EPA seeks to identify parties responsible for hazardous substances released to the environment (polluters) and either compel them to clean up the sites, or it may undertake the cleanup on its own using the Superfund, seeking to recover those costs from the responsible parties through settlements or other legal means. The EPA and state agencies use the Hazard Ranking System (HRS) to calculate a site score based on the actual or potential release of hazardous substances from a site. A score of 28.5 results in a site being placed on the National Priorities List, eligible for long-term, remedial action under the Superfund program. Sites on the NPL are considered the most highly contaminated and undergo longer-term remedial investigation and remedial action (cleanups). The state of New Jersey, the fifth smallest state in the U.S., disproportionately contains about ten percent of the priority Superfund sites. As of March 13, 2026, there were 1,343 sites listed; an additional 460 had been deleted, and 37 new sites have been proposed on the NPL.
