275
For the last time, the Roman Senate chooses an emperor; Marcus Claudius Tacitus is elected.
Marcus Claudius Tacitus ( TAS-it-əs; died June 276) was Roman emperor from 275 to 276. During his short reign he campaigned against the Goths and the Heruli, for which he received the title Gothicus Maximus.
762
Led by Muhammad al-Nafs al-Zakiyya, the Hasanid branch of the Alids begins the Alid Revolt against the Abbasid Caliphate.
Abū ʿAbd Allāh Muḥammad ibn ʿAbd Allāh ibn al-Ḥasan al-Muthannā ibn al-Ḥasan al-Mujtabā ibn ʿAlī ibn Abī Ṭālib or Muḥammad al-Nafs al-Zakiyya (Arabic: أبو عبد الله محمد بن عبد الله بن الحسن بن الحسن بن علي الملقَّب النفس الزكية, lit. 'The Pure Soul'), was a descendant of the Islamic prophet Muhammad, through his daughter Fatimah. Known for his commanding oratory skills, amiable demeanor, and impressive build, he led the Alid Revolt in Medina, a failed rebellion, against the second Abbasid caliph Al-Mansur. He and a few hundred soldiers faced against a large Abbasid force under Isa ibn Musa, and he was killed on December 6, 762 CE (145 AH).
867
Basil I is crowned Byzantine emperor in the Hagia Sophia after he murdered the previous emperor Michael III in the night before.
Basil I, nicknamed "the Macedonian" (Greek: Βασίλειος ὁ Μακεδών, romanized: Basíleios ho Makedṓn; 811 – 29 August 886), was Byzantine emperor from 867 to 886. Born to a peasant family in the theme of Macedonia, he rose to prominence in the imperial court after gaining the favour of Emperor Michael III, whose mistress he married on his emperor's orders. In 866, Michael proclaimed him co-emperor. Fearing a loss of influence, Basil orchestrated Michael's assassination the next year and installed himself as sole ruler of the empire. He was the first ruler of the Macedonian dynasty. Despite his humble origins, Basil was an effective and respected monarch. He initiated a complete overhaul of Byzantine law, an effort continued by his successor that ultimately became the Basilika. On the foreign front, he achieved military success against the heretical Paulicians, whom he subjugated in 872. He also pursued an active policy in the west, allying with Carolingian emperor Louis II against the Arabs, which led to a new period of Byzantine domination in Italy. Upon his death in a hunting accident in 886, he was succeeded by his son Leo VI, also rumoured to have been the son of Michael III.
1066
In the Battle of Stamford Bridge, Harald Hardrada, the invading King of Norway, is defeated by King Harold II of England.
The Battle of Stamford Bridge took place at the village of Stamford Bridge, East Riding of Yorkshire, in England, on 25 September 1066, between an English army under King Harold Godwinson and an invading Norwegian force led by King Harald Hardrada and the English king's brother Tostig Godwinson. After a bloody battle, both Hardrada and Tostig, along with most of the Norwegians, were killed. Although Harold Godwinson repelled the Norwegian invaders, his army was defeated by the Normans at Hastings less than three weeks later. The battle has traditionally been presented as marking the end of the Viking Age, although major Scandinavian campaigns in Britain and Ireland occurred in the following decades, such as those of King Sweyn Estrithson of Denmark in 1069–1070 and King Magnus Barefoot of Norway in 1098 and 1102–1103.
1237
England and Scotland sign the Treaty of York, establishing the location of their common border.
The Treaty of York was an agreement between the kings Henry III of England and Alexander II of Scotland, signed at York on 25 September 1237, which affirmed that Northumberland (which at the time also encompassed County Durham), Cumberland, and Westmorland were subject to English sovereignty. This established the Anglo-Scottish border in a form that remains almost unchanged to modern times (the only modifications have been regarding the Debatable Lands and Berwick-upon-Tweed). The treaty detailed the future status of several feudal properties and addressed other issues between the two kings, and historically marked the end of the Kingdom of Scotland's attempts to extend its frontier southward. The treaty was one of a number of agreements made in the ongoing relationship between the two kings. The papal legate Otho of Tonengo was already in the Kingdom of England at Henry's request, to attend a synod in London in November 1237. Otho was informed in advance by Henry of the September meeting at York, which he attended. This meeting was recorded by the contemporary chronicler Matthew Paris, who disparaged both Alexander and Otho.
1396
Ottoman Sultan Bayezid I defeats a Christian army at the Battle of Nicopolis.
The Battle of Nicopolis took place on 25 September 1396 and resulted in the rout of an allied Crusader army, assisted by the Venetian navy, at the hands of an Ottoman force, raising the siege of the Danubian fortress of Nicopolis and leading to the end of the Second Bulgarian Empire. It is often referred to as the Crusade of Nicopolis, as it was one of the last major Crusades of the Middle Ages, together with the Crusade of Varna in 1443–1444. By their victory at Nicopolis, the Turks discouraged the formation of European coalitions against them. They maintained their pressure on Constantinople, tightened their control over the Balkans, and became a greater threat to Central Europe.
1513
Spanish explorer Vasco Núñez de Balboa reaches what would become known as the Pacific Ocean.
Vasco Núñez de Balboa (Spanish pronunciation: [ˈbasko ˈnuɲeθ ðe βalˈβo.a]; c. 1475 – around January 12–21, 1519) was a Spanish explorer, governor, conquistador, adelantado, and a pirate. He is best known for being the first European to discover the Pacific Ocean while crossing the Isthmus of Panama in 1513. He traveled to the New World in 1500 and, after some exploration, settled on the island of Hispaniola. He founded the settlement of Santa María la Antigua del Darién in present-day Colombia in 1510, which was the first permanent European settlement on the mainland of the Americas (a settlement by Alonso de Ojeda the previous year at San Sebastián de Urabá had already been abandoned).
1555
The Peace of Augsburg is signed by Emperor Charles V and the princes of the Schmalkaldic League.
The Peace of Augsburg (German: Augsburger Frieden), also called the Augsburg Settlement, was a treaty between Charles V, Holy Roman Emperor and the Schmalkaldic League, signed on 25 September 1555 in the German city of Augsburg. It officially ended the religious struggle between the two groups and made the legal division of Christianity permanent within the Holy Roman Empire, allowing rulers to choose either Lutheranism or Roman Catholicism as the official confession of their state. Calvinism was not allowed until the Peace of Westphalia. The Peace of Augsburg has been described as "the first step on the road toward a European system of sovereign states." The system, created based on the Augsburg Peace, collapsed at the beginning of the 17th century, which was one of the reasons for the Thirty Years' War.
1643
The House of Commons of England accepts the Solemn League and Covenant, which promises religious reforms in England and Ireland in exchange for support of Scottish troops against king Charles I in the First English Civil War.
The House of Commons of England was the lower house of the Parliament of England from its development in the 14th century to the union of England and Scotland in 1707, when it was replaced by the House of Commons of Great Britain after the 1707 Act of Union was passed in both the English and Scottish parliaments at the time. In 1801, with the union of Great Britain and Ireland, that house was in turn replaced by the House of Commons of the United Kingdom.
1690
Publick Occurrences Both Forreign and Domestick, the first newspaper to appear in the Americas, is published for the first and only time.
Publick Occurrences Both Forreign and Domestick was the first multi-page newspaper published in British America. After its first issue, which carried an account that offended the colonial governor, the newspaper was promptly closed down by British colonial authorities, only days later. No other newspaper appeared in the colonies until fourteen years later.
1768
Unification of Nepal
The Unification of Nepal was the historical process of military conquest, strategic diplomacy, and state-building through which the Hill Kingdom of Gorkha unified dozens of fragmented kingdoms into the sovereign state of modern Nepal. Initiated in 1743 CE by King Prithvi Narayan Shah upon his ascension to the Gorkha throne, the unification campaign spanned over seven decades, concluding after the Anglo-Nepalese War with the Treaty of Sugauli in 1816 CE, which established the nation's formal international boundaries.
1775
American Revolutionary War: Ethan Allen surrenders to British forces after attempting to capture Montreal in the Battle of Longue-Pointe during the invasion of Quebec.
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 had led King George III and much of 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 colonial Empire 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 in a panic, on March 5, 1770. In mid-1774, with tensions escalating even further between the British Army and the Continental army, the British Parliament imposed the Intolerable Acts, an attempt to disarm British-American colonists, 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 pretty 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 armed force led under the command of John Burgoyne was forced to surrender at Saratoga in an American victory that also proved a crucial role 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). American Indian 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 British American colonists 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.
1775
American Revolutionary War: Benedict Arnold's expedition to Quebec sets off to join the American invasion.
Benedict Arnold (January 14, 1741 [O.S. January 3, 1740] – June 14, 1801) was an American-born British military officer who served during the American Revolutionary War. He fought with distinction for the American Continental Army and rose to the rank of major general before defecting to the British in 1780. General George Washington had given him his fullest trust and had placed him in command of West Point in New York. Arnold was planning to surrender the fort to British forces, but the plot was discovered in September 1780, whereupon he fled to the British lines. In the later part of the war, Arnold was commissioned as a brigadier general in the British Army and placed in command of the American Legion. He led British forces in battle against the army which he had once commanded, and his name became synonymous with treason and betrayal in the United States. Born in Connecticut, Arnold was a merchant operating ships in the Atlantic when the war began. He joined the growing American army outside of Boston and distinguished himself by acts that demonstrated intelligence and bravery: In 1775, he captured Fort Ticonderoga. In 1776, he employed defensive and delaying tactics at the Battle of Valcour Island on Lake Champlain that gave American forces time to prepare New York's defenses. His performance in the Battle of Ridgefield in Connecticut prompted his promotion to major general. He conducted operations that provided the Americans with relief during the Siege of Fort Stanwix, and key actions during the pivotal 1777 Battles of Saratoga in which he sustained leg injuries that put him out of combat for several years. Arnold repeatedly claimed that he was being passed over for promotion by the Second Continental Congress, and that other officers were being given credit for some of his accomplishments. Some in his military and political circles charged him with corruption. After formal inquiries, he was acquitted of all but two minor charges, but Congress investigated his finances and determined that he was indebted to Congress and that he had borrowed money heavily to maintain a lavish lifestyle. Arnold mingled with Loyalist sympathizers in Philadelphia and married into the Loyalist family of Peggy Shippen. She was a close friend of British Major John André and kept in contact with him when he became head of the British espionage system in New York. Many historians see her as having facilitated Arnold's plans to switch sides; he opened secret negotiations with André, and she relayed their messages to each other. The British promised £20,000 (equivalent to £3,104,000 in 2025) for the capture of West Point, a major American stronghold. Washington greatly admired Arnold and gave him command of that fort in July 1780. Arnold planned to surrender the fort to the British, but it was exposed in September 1780 when American militiamen captured André carrying papers which revealed the plot. Arnold escaped, and André was hanged. Arnold received a commission as a brigadier general in the British Army, an annual pension of £360 (equivalent to £56,000 in 2025) and a lump sum of over £6,000 (equivalent to £931,000 in 2025). He led British forces in the raid on Richmond and oversaw a raid on New London, Connecticut, which burned much of it to the ground. Arnold also commanded British forces at the Battle of Blandford and the Battle of Groton Heights, the latter taking place just a few miles downriver from the town where he had grown up. In the winter of 1782, he and Shippen moved to London. He was well received by King George III and the Tories but frowned upon by the Whigs and most British Army officers. In 1787, he moved to the colony of New Brunswick in what is now Canada to run a merchant business with his sons Richard and Henry. He was extremely unpopular there and returned to London permanently in 1791, where he died ten years later.
1786
The mine of Huancavelica in the Peruvian Andes collapses, killing more than two hundred people.
The event was a major setback for mercury production in the Spanish Empire.
Huancavelica or Wankawillka in Quechua is a city in Peru. It is the capital of the department of Huancavelica and according to the 2017 census had a population of 49,570 people. The city was established on August 5, 1572 by the Viceroy of Peru Francisco de Toledo. Indigenous peoples represent a major percentage of the population. It has an approximate altitude of 3,676 metres (12,060 ft); the climate is cold and dry between the months of February and August with a rainy season between September and January. It is considered one of the poorest cities in Peru.
1789
The United States Congress passes twelve constitutional amendments: the ten known as the Bill of Rights, the (unratified) Congressional Apportionment Amendment, and the Congressional Compensation Amendment.
The United States Bill of Rights comprises the first ten amendments to the United States Constitution. It was proposed following the often bitter 1787–88 debate over the ratification of the Constitution and written to address the objections raised by Anti-Federalists. The amendments of the Bill of Rights add to the Constitution specific guarantees of personal freedoms, such as freedom of speech, the right to publish, practice religion, possess firearms, to assemble, and other natural and legal rights. Its clear limitations on the government's power in judicial and other proceedings include explicit declarations that all powers not specifically granted to the federal government by the Constitution are reserved to the states or the people. The concepts codified in these amendments are built upon those in earlier documents, especially the Virginia Declaration of Rights (1776), as well as the Northwest Ordinance (1787), the English Bill of Rights (1689), and Magna Carta (1215).
1790
Four Great Anhui Troupes introduce Anhui opera to Beijing in honor of the Qianlong Emperor's eightieth birthday.
Anhui Opera, also known as Huiju [徽剧], is a traditional Chinese opera form that originated in Anhui Province during the Ming Dynasty. It is a crucial part of Huizhou culture and significantly contributed to the development of Peking Opera.
1804
The Teton Sioux (a subdivision of the Lakota) demand one of the boats from the Lewis and Clark Expedition as a toll for allowing the expedition to move further upriver.
The Lewis and Clark Expedition, also known as the Corps of Discovery Expedition, was the United States expedition to cross the newly acquired western portion of the country after the Louisiana Purchase. The Corps of Discovery was a select group of U.S. Army and civilian volunteers under the command of Captain Meriwether Lewis and his close friend Second Lieutenant William Clark. Clark, along with 30 others, set out from Camp Dubois (Camp Wood), Illinois, on May 14, 1804, met Lewis and ten other members of the group in St. Charles, Missouri, then went up the Missouri River. The expedition crossed the Continental Divide of the Americas near the Lemhi Pass, eventually coming to the Columbia River, and the Pacific Ocean in 1805. The return voyage began on March 23, 1806, at Fort Clatsop, Oregon, ending six months later on September 23. President Thomas Jefferson commissioned the expedition, shortly after the Louisiana Purchase of 1803, to explore and detail as much of the new territory as possible. Furthermore, he wished to find a practical travel route across the western half of the continent—directly avoiding the hot and desolate desert southwest—and to establish an American presence in the new lands before European powers attempted to establish claims of their own. The campaign's secondary objectives were scientific, economical and humanitarian, i.e., to document the West's biodiversity, topography and geography and to establish positive trade relations with (potentially unknown) Native American tribes. The expedition returned to St. Louis to report their findings to President Jefferson via maps, sketches, and various journals.
1868
The Imperial Russian steam frigate Alexander Nevsky is shipwrecked off Jutland while carrying Grand Duke Alexei Alexandrovich of Russia.
Alexander Nevsky (Russian: Александр Невский) was a large screw frigate of the Russian Imperial Navy. The ship was designed as part of a challenge being offered by the Russian Empire to the Royal Navy, but was lost in a shipwreck in 1868 while Grand Duke Alexei, son of Tsar Alexander II, was aboard.
1890
The United States Congress establishes Sequoia National Park.
Sequoia National Park is a national park of the United States in the southern Sierra Nevada east of Visalia, California. The park was established on September 25, 1890, and today protects 404,064 acres (631 sq mi; 163,519 ha; 1,635 km2) of forested mountainous terrain. Encompassing a vertical relief of nearly 13,000 feet (4,000 m), the park contains the highest point in the contiguous United States, Mount Whitney, at 14,505 feet (4,421 m) above sea level. The park is south of, and contiguous with, Kings Canyon National Park; both parks are administered by the National Park Service together as Sequoia and Kings Canyon National Parks. UNESCO designated the areas as Sequoia-Kings Canyon Biosphere Reserve in 1976. The park is notable for its giant sequoia trees, including the General Sherman Tree, the largest tree on Earth by volume. The General Sherman Tree grows in the Giant Forest, which contains five of the ten largest trees in the world. The Giant Forest is connected by the Generals Highway to Kings Canyon National Park's General Grant Grove, home of the General Grant Tree among other giant sequoias. The park's giant sequoia forests are part of 202,430 acres (316 sq mi; 81,921 ha; 819 km2) of old-growth forests shared by Sequoia and Kings Canyon National Parks. The parks preserve a landscape that was the ancestral homelands of the Monache (Western Mono), the Tubatulabal, the Owens Valley Paiute, the Yokuts, and the Shoshone (Newe) tribes prior to Euro-American settlement.
1906
Leonardo Torres Quevedo demonstrates the Telekino in the Bilbao Abra (Spain), guiding an electric boat from the shore with people on board, which was controlled at a distance over 2 km (1.2 mi), in what is considered to be the origin of modern wireless remote-control operation principles.
Leonardo Torres Quevedo (Spanish: [leoˈnaɾðo ˈtores keˈβeðo]; 28 December 1852 – 18 December 1936) was a Spanish civil engineer, mathematician, and inventor who developed numerous engineering innovations related to aerial trams, airships, catamarans, and remote control. He was also a pioneer in the fields of computing and robotics, while maintaining an active role in several scientific and cultural institutions. He held prominent positions, such as Seat N of the Real Academia Española (1920–1936) and the presidency of the Spanish Royal Academy of Sciences (1928–1934). In 1927, he became a foreign associate of the French Academy of Sciences. His first innovative design was a cableway system patented in 1887 for the safe transport of passengers, an endeavor that led to the Mount Ulia aerial ropeway in 1907 and culminated in 1916 with the opening of the Whirlpool Aero Car at Niagara Falls. In the 1890s, Torres focused his efforts on analog computation. He published Sur les machines algébriques (1895) and Machines à calculer (1901), technical studies that earned him recognition in France for his construction of machines capable of solving real and complex roots of polynomials. At the beginning of the 20th century, he made significant aeronautical contributions by developing the non-rigid Astra-Torres airships, whose trilobed structure helped the British and French armies counter Germany's submarine warfare during World War I. This work in aeronautics would lead him to become a key figure in the development of radio control systems between 1901 and 1905 with the Telekino, which introduced modern wireless remote control operation principles. From his Laboratory of Automatics established in Madrid in 1907, Torres built El Ajedrecista (The Chess Player) in 1912, an electromagnetic device capable of playing a chess endgame which demonstrated that machines could follow specific rules and heuristics, contributing to early developments in physical automata and artificial intelligence. Expanding upon the work of Charles Babbage in his 1914 paper Essays on Automatics, he explored theories of thinking machines and designed a special-purpose electromechanical calculator that conceptually foreshadowed floating-point arithmetic. British historian Brian Randell described it as "a fascinating work which well repays reading even today." Torres later demonstrated the feasibility of an electromechanical analytical engine by successfully producing a typewriter-controlled calculating machine in 1920. Before his retirement in 1930, Torres conceived other advanced designs, particularly in the field of naval architecture. Among the most notable were the Buque campamento (Camp-Vessel, 1913), a balloon carrier designed to transport airships attached to a mooring mast of his invention, and the Binave (Twin Ship, 1916), a multihull steel vessel featuring flexible structural joints and independent propulsion systems that solved the stability and torsion issues of earlier catamarans. In addition to his interests in engineering, Torres also stood out in the field of letters and was a prominent speaker and supporter of Esperanto.
1911
An explosion of badly degraded propellant charges on board the French battleship Liberté detonates the forward ammunition magazines and destroys the ship.
Liberté was a pre-dreadnought battleship built for the French Navy in the mid-1900s. She was the lead ship of the Liberté class, which included three other vessels and was a derivative of the preceding République class, with the primary difference being the inclusion of a heavier secondary battery. Liberté carried a main battery of four 305-millimeter (12 in) guns, like the République, but mounted ten 194 mm (7.6 in) guns for her secondary armament in place of the 164 mm (6.5 in) guns of the earlier vessels. Like many late pre-dreadnought designs, Liberté was completed after the revolutionary British battleship HMS Dreadnought had entered service, rendering her obsolescent. On entering service, Liberté was assigned to the 2nd Division of the Mediterranean Squadron, based in Toulon. She immediately began the normal peacetime training routine of squadron and fleet maneuvers and cruises to various ports in the Mediterranean. She also participated in several naval reviews for a number of French and foreign dignitaries. In September 1909, the ships of the 2nd Division crossed the Atlantic to the United States to represent France at the Hudson–Fulton Celebration. Liberté's active career was cut short on 25 September 1911 when a fire broke out in one of the ship's propellant magazines and led to a detonation of the charges stored there, destroying the ship in a tremendous explosion that killed 286 of her crew. The blast also damaged several other vessels and killed crewmen on six neighboring ships. An investigation revealed that the standard French propellant, Poudre B, was prone to decomposition that rendered it very unstable; it had likely been the culprit in several other ammunition fires in other ships. The wreck remained in Toulon until 1925, when her destroyed hull was refloated, towed into a drydock, and broken up.
1912
Columbia University Graduate School of Journalism is founded in New York City.
The Columbia University Graduate School of Journalism is the journalism school of Columbia University, located in the Morningside Heights neighborhood of Manhattan, New York City, United States. Admissions to the school are highly selective; traditionally drawing upon an international student body. Alumni have gone on to win Pulitzer Prizes, or have become newsroom leaders in respected publications. The journalism school offers four graduate degree programs, in addition to offering professional development programs, fellowships, workshops and institutes, namely the Tow Center for Digital Journalism, the Brown Institute for Media Innovation, and until 2025, the Dart Center for Journalism and Trauma which is now the independent Global Center for Journalism and Trauma. The school publishes the Columbia Journalism Review, facilities with the Pulitzer Prizes, and directly administers the Alfred I. duPont–Columbia University Award, the Maria Moors Cabot Prizes, the John Chancellor Award for Excellence in Journalism, the Lukas Prizes, the Oakes Prizes, the Meyer Berger Award, the Paul Tobenkin Memorial Award and the Dart Awards for Excellence in Coverage of Trauma. It also co-sponsors the National Magazine Awards with the American Society of Magazine Editors, which administers the program. The school has an accreditation from the Association for Education in Journalism and Mass Communication.
1915
World War I: The Second Battle of Champagne begins.
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 caused 15 to 22 million deaths, including those resulting from war crimes and genocides. The war also contributed to the spread of the Spanish flu pandemic. The conflict saw important developments in weaponry, including machine guns, artillery, aircraft, chemical weapons, and tanks.
1918
World War I: The end of the Battle of Megiddo, the climax of the British Army's Sinai and Palestine campaign under General Edmund Allenby.
The Battle of Megiddo was fought between 19 and 25 September 1918, on the Plain of Sharon, in front of Tulkarm, Tabsor and Arara in the Judean Hills as well as on the Esdralon Plain at Nazareth, Afulah, Beisan, Jenin and Samakh. Its name, which has been described as "perhaps misleading" since very limited fighting took place near Tel Megiddo, was chosen by British commander Edmund Allenby for its biblical and symbolic resonance. The battle was the final Allied offensive of the Sinai and Palestine Campaign of World War I. The contending forces were the Allied Egyptian Expeditionary Force, of three corps including one of mounted troops, and the Ottoman Yildirim Army Group which numbered three armies, each the strength of barely an Allied corps. The series of battles took place in what was then the central and northern parts of Ottoman Palestine and parts of present-day Israel, Syria and Jordan. After forces of the Arab Revolt attacked the Ottoman lines of communication, distracting the Ottomans, British and Indian infantry divisions attacked and broke through the Ottoman defensive lines in the sector adjacent to the coast in the set-piece Battle of Sharon. The Desert Mounted Corps rode through the breach and almost encircled the Ottoman Seventh and Eighth armies still fighting in the Judean Hills. The subsidiary Battle of Nablus was fought virtually simultaneously in the Judean Hills in front of Nablus and at crossings of the Jordan River. The Ottoman Fourth Army was subsequently attacked in the Hills of Moab at Es Salt and Amman. These battles resulted in many tens of thousands of prisoners and many miles of territory being captured by the Allies. Following the battles, Daraa was captured on 27 September, Damascus on 1 October and operations at Haritan, north of Aleppo, were still in progress when the Armistice of Mudros was signed ending hostilities between the Allies and Ottomans. The operations of General Edmund Allenby, the British commander of the Egyptian Expeditionary Force, achieved decisive results at comparatively little cost, in contrast to many offensives during the First World War. Allenby achieved this through the use of creeping barrages to cover set-piece infantry attacks to break a state of trench warfare and then use his mobile forces (cavalry, armoured cars and aircraft) to encircle the Ottoman armies' positions in the Judean Hills, cutting off their lines of retreat. The irregular forces of the Arab Revolt also played a part in this victory.
1937
Second Sino-Japanese War: The Chinese Eighth Route Army gains a minor, but morale-boosting victory in the Battle of Pingxingguan.
The Second Sino-Japanese War was fought between the Republic of China and the Empire of Japan and its puppet states between 1937 and 1945, following a period of conflict localized to Manchuria that started in 1931. It is often regarded as the beginning of World War II in Asia, as the wars became heavily intertwined after Japan attacked the United States. It was the largest Asian war in the 20th century. On 18 September 1931, the Japanese staged the Mukden incident, a false flag event fabricated to justify their invasion of Manchuria and establishment of the puppet state of Manchukuo. This is sometimes marked as the beginning of the war. From 1931 to 1937, China and Japan engaged in skirmishes, including in Shanghai and in Northern China. Nationalist and Chinese Communist Party (CCP) forces, respectively led by Chiang Kai-shek and Mao Zedong, had fought each other in the Chinese Civil War since 1927. In late 1933, Chiang Kai-shek encircled the Chinese Communists in an attempt to finally destroy them, forcing the Communists into the Long March, resulting in the Communists losing around 90% of their men. As a Japanese invasion became imminent, Chiang eventually formed a United Front with the Communists in 1936, a process that was hastened by the Xi'an Incident. The war is considered to have begun on 7 July 1937 after the Marco Polo Bridge incident near Beijing, which escalated into full-scale Japanese invasion of the rest of China. Following the protracted Battle of Shanghai, the Japanese captured the capital of Nanjing in 1937 and perpetrated the Nanjing Massacre. After failing to stop the Japanese capture of Wuhan in 1938, China's de facto capital at the time, the Nationalist government relocated to Chongqing in the Chinese interior. After the Sino-Soviet Non-Aggression Pact, Soviet aid bolstered the National Revolutionary Army and Air Force. By 1939, after Chinese victories at Changsha and with Japan's lines of communication stretched deep into the interior, the war reached a stalemate. The Japanese were unable to defeat CCP forces in Shaanxi, who waged a campaign of sabotage and guerrilla warfare. In November 1939, Nationalist forces launched a large scale winter offensive, and in August 1940, CCP forces launched the Hundred Regiments Offensive in central China. In retaliation, Japanese forces implemented massive scorched earth policies in North and Central China, killing millions of civilians. In April 1941, Soviet aid was halted with the Soviet–Japanese Neutrality Pact. In December 1941, Japan launched a surprise attack on Pearl Harbor and declared war on the United States and the United Kingdom. The US increased its aid to China under the Lend-Lease Act, becoming its main financial and military supporter. The British Empire supported the Chinese forces against Japan by sending supplies through the Burma Road, linking British colonies in India and Burma to China. Chinese forces also fought with British Empire forces against the Japanese in the Burma campaign to restore Allied usage after the Japanese occupied most of the Burma Road. With Burma cut off, the United States Army Air Forces airlifted material over the Himalayas. In 1944, Japan launched Operation Ichi-Go, the invasion of Henan and Changsha. In 1945, the Chinese Expeditionary Force resumed its advance in Burma and completed the Ledo Road linking India to China. China launched large counteroffensives in South China, repulsed a failed Japanese invasion of West Hunan, and recaptured Japanese occupied regions of Guangxi. Japan formally surrendered on 2 September 1945, following the atomic bombings of Hiroshima and Nagasaki, Soviet declaration of war and subsequent invasion of Manchuria, Inner Mongolia and Korea. The war resulted in the deaths of around 20 million people, mostly Chinese civilians. Japan carried out the largest attacks in the history of biological warfare, causing at least 200,000 deaths, and used chemical weapons including lethal blister agents. China was recognized as one of the Big Four Allied powers in World War II and one of the "Four Policemen", which formed the foundation of the United Nations. It regained Taiwan and became one of the five permanent members of the United Nations Security Council. The Japanese surrender ceremony that ended World War II in China, occurred in Nanjing on 9 September 1945. The forces of the Imperial Japanese Army agreed with the Allies terms to cease all armed conflict in the Pacific. During the 15-minute ceremony, General Yasuji Okamura, Commander-in-Chief of the Chinese Expeditionary Force of the Imperial Japanese Army, signed the surrender document which was written in both Japanese and Chinese. The unconditional surrender was overseen and accepted by Kuomintang General He Yingqin, the Chinese representative of Allies of World War II and the commander-in-chief of the Republic of China National Revolutionary Army and British Major-General Eric Hayes. The Chinese Civil War resumed in 1946, ending with a communist victory and the Proclamation of the People's Republic of China in 1949, while the government of the Republic of China relocated to Taiwan.

Since its establishment, the RJAF has undergone significant modernization efforts, enhancing its capabilities to address evolving security challenges. The force also collaborates closely with international allies, including the United States and several NATO countries, engaging in joint training exercises and defense partnerships. The RJAF has earned a respected position within the Middle East due to its skilled personnel and its contributions to stability and security in the region. With a focus on training and technological advancement, the RJAF continues to enhance its readiness and operational capabilities, representing a critical component of Jordan's defense infrastructure.

Central High School in Little Rock, Arkansas, is integrated by the use of United States Army troops.
Little Rock Central High School (LRCH) is an accredited comprehensive public high school in Little Rock, Arkansas, United States. The school was the site of the Little Rock Crisis in 1957 after the U.S. Supreme Court ruled that segregation by race in public schools was unconstitutional three years earlier. This was during the period of heightened activism in the civil rights movement. Central is located at the intersection of Little Rock Nine Way (a section of Park Street, designated in September 2022) and Daisy L. Gatson Bates Drive (formerly 14th Street). Bates was an African-American journalist and state NAACP president who played a key role in bringing about, through the 1957 crisis, the integration of the school. Central can trace its origins to 1869 when the Sherman School operated in a wooden structure at 8th and Sherman streets; it graduated its first class on June 13, 1873. In 1885 the Sherman School was moved to 14th and Scott streets and was named Scott Street School, but was more commonly called City High School. Five years later in 1890, the Peabody School was constructed at West Capitol and Gaines streets. It was named in honor of philanthropist George Peabody from US$200,000 received via the Peabody Education Fund. In 1905, the city founded Little Rock High School at the intersection of 14th and Cumberland streets, and shuttered the Peabody and Scott Street schools to serve as the city's sole public high school. Until 1957, only white students were permitted to be enrolled. In 1927 at a cost of US$1.5 million, the city completed construction on the nation's largest and most expensive high school facility, which remains in use today. In 1953 with the construction of Hall High School, the school was renamed as Little Rock Central High School. It has since been listed on the U.S. National Register of Historic Places and named as a U.S. National Historic Landmark and National Historic Site. Central High School, which covers grades 9 through 12, had an enrollment of 2,476 in school year 2020–2021. It is in the Little Rock School District, and serves sections of Little Rock and the entirety of Cammack Village. Nancy Rousseau was appointed principal in 2002, and retained that position as of 2024.

S.
W. R. D. Bandaranaike, Prime Minister of Ceylon, is mortally shot by a Buddhist monk, Talduwe Somarama, and dies the next day.
Solomon West Ridgeway Dias Bandaranaike (8 January 1899 – 26 September 1959), also known as "The Silver Bell of Asia" (ආසියාවේ රිදී සීනුව), was a Ceylonese statesman who served as the fourth Prime Minister of the Dominion of Ceylon (now Sri Lanka), from 1956 until his assassination in 1959. The founder of the left-wing and Sinhalese nationalist Sri Lanka Freedom Party (SLFP), he was elected the fourth Prime Minister of Ceylon after creating a powerful coalition called the Mahajana Eksath Peramuna and contesting on the lines of Sinhalese nationalism and democratic socialism. He achieved a landslide victory over the ruling United National Party in the general elections in 1956. His tenure saw some of the first left wing reforms instituted by the Freedom Party in Sri Lanka such as nationalizing the bus services and introducing legislation to prohibit caste based discrimination. Bandaranaike further consolidated Sri Lanka's newly gained independence by formally abrogating the 1947 United Kingdom–Ceylon Defence Agreement and establishing diplomatic missions with a number of communist states. He implemented a new language policy, the Sinhala Only Act, making Sinhala the sole official language of the country, creating much controversy. On 25 September 1959, Bandaranaike was shot at his town house in Colombo and died of his wounds the day after. A Buddhist monk named Ven Talduwe Somarama was arrested, convicted and hanged for the murder of Bandaranaike. Minister of Education and the acting leader of the house, Wijeyananda Dahanayake was appointed caretaker prime minister by the Governor General and was confirmed by Parliament. Bandaranaike's widow Sirimavo Bandaranaike led the Freedom Party to gain a majority in parliament and was democratically elected the first female prime minister in the world. She expanded on her husband's left-wing reforms in her first two terms as prime minister from 1960 to 1965 and from 1970 to 1977. In 1994, Bandaranaike's daughter Chandrika Kumaratunga headed a coalition led by the Freedom Party to be elected prime minister and thereafter president serving from 1994 to 2005. Sirimavo Bandaranaike returned to office for a third term as prime minister in 1994, serving until her retirement in 2000. Their son, Anura Bandaranaike, served as Speaker of the Parliament of Sri Lanka from 2000 to 2001.
