October 10 in History

The 10s decade ran from January 1, AD 10, to December 31, AD 19. In Europe, the decade saw the end of the Early Imperial campaigns in Germania when Roman forces led by Germanicus defeated Germanic tribes in the Battle of Idistaviso in AD 16. In the subsequent year, a war broke out between Maroboduus and Arminius. In Africa, Tacfarinas led his own Musulamii tribe and a loose and changing coalition of other Berber tribes in a war against the Romans in North Africa during the rule of the emperor Tiberius (AD 14–37). The Armenian Artaxiad dynasty was overthrown by the Romans. In China, the Red Eyebrows Rebellion erupted against Wang Mang, emperor of the Xin dynasty. In Korea, Daeso, the ruler of the kingdom of Dongbuyeo, led his armies into Goguryeo once again. This time, Muhyul, a prince of Goguryeo, led the armies of Goguryeo in a well-planned ambush and slaughtered all of Daeso's army. Only he and a few of his men escaped home. Literary works from the 10s include works from the ancient Roman poet Ovid, Tristia and Epistulae ex Ponto, while Nicolaus of Damascus wrote a biography of Emperor Augustus (Bios Kaisaros). In the Roman Empire, an edict was issued effecting an empire-wide ban on divinatory practices especially astrology. The edict requires any consultation between a customer and a practitioner to be conducted with at least one third party witness present and bans inquiry into anyone's death. A large earthquake caused the destruction of at least twelve cities in the region of Lydia in the Roman province of Asia in Asia Minor. In China, a major flooding took place in the Yellow River in AD 11, which is credited with helping bring about the fall of the Xin dynasty in the next decade. Manning (2008) tentatively estimates the world population in AD 10 as 241 million.

Hagia Sophia, officially the Hagia Sophia Grand Mosque, is a mosque and a major cultural and historical site in Istanbul, Turkey. It was formerly a church (360–1453) and a museum (1935–2020). The last of three church buildings to be successively erected on the site by the Eastern Roman Empire, it was completed in AD 537, becoming the world's largest interior space and among the first to employ a fully pendentive dome. It is considered the epitome of Byzantine architecture and is said to have "changed the history of architecture". From its dedication in 360 until 1453, Hagia Sophia served as the cathedral of Constantinople in the Byzantine liturgical tradition, except for the period 1204–1261 when the Latin Crusaders installed their own hierarchy. After the fall of Constantinople in 1453, it served as a mosque, having its minarets added soon after. The site became a museum in 1935, and was redesignated as a mosque in 2020.

The Battle of Karbala (Arabic: مَعْرَكَة كَرْبَلَاء, romanized: Maʿrakat Karbalāʾ) was fought on 10 October 680 (10 Muharram in the year 61 AH of the Islamic calendar) between the forces of the second Umayyad caliph Yazid I (r. 680–683), and a small army led by Husayn ibn Ali, second son of Ali and grandson of the Islamic prophet Muhammad, at Karbala, in modern-day southern Iraq. Prior to his death, the Umayyad caliph Mu'awiya I (r. 661–680) appointed his son Yazid as his successor, making the caliphate hereditary. Yazid's nomination was contested by Husayn and other notables, and after Mu'awiya died in 680, Yazid demanded allegiance from Husayn and the other dissidents. Husayn refused and took refuge in Mecca. While Husayn was in Mecca, the residents of Kufa, the center of Ali's caliphate, sent him numerous letters inviting him to overthrow Umayyad rule, and pledging their allegiance to him. Husayn first sent his cousin, Muslim ibn Aqil, to Kufa to assess the situation and the genuineness of their support. After receiving a favorable report from Muslim, Husayn accepted their invitation and traveled toward the city in response to their calls. On his way to Kufa with about 72 men, Husayn's caravan was intercepted by a 1,000-strong army of the caliph at some distance from Kufa. He was forced to head north and encamp at the plains of Karbala on 2 October, where another 4,000-strong Umayyad army arrived soon afterwards. Negotiations failed after the Umayyad governor Ubayd Allah ibn Ziyad refused to grant Husayn safe passage unless he submitted to his authority, a condition Husayn rejected. The battle ensued on 10 October, during which Husayn was killed along with most of his family members and close companions, while the surviving members of his family were taken captive and brought first to Kufa and then to Damascus. This sparked the Second Fitna, during which the people of Kufa organized two campaigns to avenge the killing of Husayn; first by the Tawwabin, and the second by Mukhtar al-Thaqafi, who ruled over much of Iraq and parts of northwestern Iran for eighteen months and killed several figures responsible for Husayn's death. The Battle of Karbala gave the early political party of pro-Alids, which had not yet developed specific theological doctrines and set of rituals, a distinct religious identity and helped transform and consolidate it into a separate religious sect. Heinz Halm writes: "There was no religious aspect to Shi'ism prior to 680. The death of the third imam and his followers marked the 'big bang' that created the rapidly expanding cosmos of Shi'ism and brought it into motion."

Charles Martel, Martel being an Old French sobriquet meaning "The Hammer", was a Frankish political and military leader who, as Duke and Prince of the Franks and Mayor of the Palace, was the de facto ruler of the Franks from 718 until his death. He was a son of the Frankish statesman Pepin of Herstal and a noblewoman named Alpaida. Charles successfully asserted his claims to power as successor to his father as the power behind the throne in Frankish politics. Continuing and building on his father's work, he restored centralized government in Francia and began a series of military campaigns that re-established the Franks as the undisputed masters of all Gaul. According to the contemporary Liber Historiae Francorum, Charles was "a warrior who was uncommonly ... effective in battle".

Sten Sture the Elder (Swedish: Sten Sture den äldre; 1440 – 14 December 1503) was a Swedish statesman and regent of Sweden from 1470 to 1497 and again from 1501 to 1503. As the leader of the victorious Swedish separatist forces against the royal unionist forces led by Danish king Christian I during the Battle of Brunkeberg in 1471, he weakened the Kalmar Union considerably and became the effective ruler of Sweden as Lord Regent for most of his remaining life.

Christopher Columbus was an Italian explorer and navigator from the Republic of Genoa who completed four Spanish transatlantic voyages in the name of the Catholic Monarchs, opening the way for the widespread European exploration and colonization of the Americas. His expeditions were the first known European contact with the Caribbean and Central and South America.

The Kingdom of Hormuz was a kingdom ruled by a dynasty of southern Arab origin. It was located in the eastern side of the Persian Gulf and extended as far as Bahrain in the west at its zenith. The Kingdom was established in the 11th century initially as a dependency of the Kerman Seljuk Sultanate, and later as an autonomous tributary of the Salghurid Turkmens and the Ilkhanate. In its last phase Hormuz became a client state of the Portuguese Empire in the East.

Henri I de Lorraine, Duke of Guise, Prince of Joinville, Count of Eu, sometimes called Le Balafré ('Scarface'), was the eldest son of François, Duke of Guise, and Anna d'Este. His maternal grandparents were Ercole II d'Este, Duke of Ferrara, and Renée of France. Through his maternal grandfather, he was a descendant of Lucrezia Borgia and Pope Alexander VI.

The Kingdom of Ireland was a dependency of England from 1542 to 1707, and then of Great Britain from 1707 to 1800. It was ruled by the monarchs of England and then of Great Britain in personal union, and was administered from Dublin Castle by a viceroy appointed by the English king: the Lord Lieutenant of Ireland. By the late 17th century, the state was dominated by the Protestant Anglo-Irish minority, known as the Protestant Ascendancy. The Protestant Church of Ireland was the state church. The Parliament of Ireland was almost exclusively Anglo-Irish. From 1661, the administration controlled an Irish army. Although formally a kingdom in personal union on equal footing with England and later Great Britain, for most of its history it was de facto a dependency. This status was enshrined in the Declaratory Act 1719.

The Great Hurricane of 1780 was the deadliest tropical cyclone in the Western Hemisphere. An estimated 22,000 people died throughout the Lesser Antilles when the storm passed through the islands from October 10 to October 16. Specifics on the hurricane's track and strength are unknown, as the official Atlantic hurricane database only goes back to 1851. The hurricane struck Barbados likely as a Category 5 hurricane, with one estimate of wind gusts as high as 200 mph (320 km/h), before moving past Martinique, Saint Lucia, and Sint Eustatius, and causing thousands of deaths on those islands. Coming in the midst of the American Revolution, the storm caused heavy losses to the British fleet contesting for control of the area, significantly weakening British control over the Atlantic. The hurricane later passed near Puerto Rico and over the eastern portion of Hispaniola, causing heavy damage near the coastlines. It ultimately turned to the northeast and was last observed on October 20 southeast of Atlantic Canada. The death toll from the Great Hurricane alone exceeds that of many entire decades of Atlantic hurricanes. Estimates are significantly higher than for the 1998 Hurricane Mitch, the second-deadliest Atlantic storm, for which figures are likely more precise. The hurricane was part of the disastrous 1780 Atlantic hurricane season, with two other deadly storms occurring in October.

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.

Annapolis is the capital of the U.S. state of Maryland. It is the county seat of Anne Arundel County and its only incorporated city. Situated on the Chesapeake Bay at the mouth of the Severn River, Annapolis is a historic city with a strong maritime culture. It is 25 miles (40 km) south of Baltimore and about 30 miles (50 km) east of Washington, D.C., forming part of the Baltimore–Washington metropolitan area. The 2020 census recorded its population as 40,812, an increase of 6.3% since 2010.

Triton is the largest natural satellite of the planet Neptune. It is the only moon of Neptune massive enough to be rounded under its own gravity and hosts a thin, hazy atmosphere. Triton orbits Neptune in a retrograde orbit—revolving in the opposite direction to the parent planet's rotation—the only large moon in the Solar System to do so. Triton is thought to have once been a dwarf planet from the Kuiper belt, captured into Neptune's orbit by the latter's gravity. At 2,706.8 kilometers (1,681.9 mi) in diameter, Triton is the seventh-largest moon in the Solar System, the second-largest planetary moon in relation to its primary (after Earth's Moon), and larger than all of the known dwarf planets. The mean density is 2.061 g/cm3, reflecting a composition of approximately 30–45% water ice by mass, with the rest being mostly rock and metal. Triton is differentiated, with a crust of primarily ice atop a probable subsurface ocean of liquid water and a solid rocky-metallic core at its center. Although Triton's orbit is nearly circular with a very low orbital eccentricity of 0.00001, its interior may still experience tidal heating through obliquity tides. Triton is one of the most geologically active worlds in the Solar System, with an estimated average surface age of less than 100 million years old. Its surface is covered by frozen nitrogen and is geologically young, with very few impact craters. Young, intricate cryovolcanic and tectonic terrains suggest a complex geological history. The atmosphere of Triton is composed primarily of nitrogen, with minor components of methane and carbon monoxide. Triton's atmosphere is relatively thin and strongly variable, with its atmospheric surface pressure varying by up to a factor of three within the past 30 years. Triton's atmosphere supports clouds of nitrogen ice crystals and a layer of organic atmospheric haze. Triton was the first Neptunian moon to be discovered, on October 10, 1846, by English astronomer William Lassell. The 1989 flyby of Triton by the Voyager 2 spacecraft remains the only up-close visit to the moon as of 2026. As the probe was able to study only about 40% of the moon's surface, multiple concept missions have been developed to revisit Triton. These include a Discovery-class Trident and New Frontiers-class Triton Ocean Worlds Surveyor and Nautilus.

The Ten Years' War (Spanish: Guerra de los Diez Años; 1868–1878), also known as the Great War (Guerra Grande) and the War of '68, was a war of independence of Cuba from Spain. The uprising was led by Cuban-born planters and other wealthy natives. On 10 October 1868, sugar mill owner Carlos Manuel de Céspedes and his followers proclaimed independence, beginning the conflict. This was the first of three liberation wars that Cuba fought against Spain, the other two being the Little War (1879–1880) and the Cuban War of Independence (1895–1898). The final three months of the last conflict escalated with United States involvement, leading to the Spanish–American War.

The Women's Social and Political Union (WSPU) was a women-only political movement and leading militant organisation campaigning for women's suffrage in the United Kingdom founded in 1903. Known from 1906 as the suffragettes, its membership and policies were tightly controlled by Emmeline Pankhurst and her daughters Christabel and Sylvia. The WSPU membership became known for civil disobedience and direct action. Emmeline Pankhurst described them as engaging in a "reign of terror". Group members heckled politicians, held demonstrations and marches, broke the law to force arrests, broke windows in prominent buildings, set fire to or introduced chemicals into postboxes thus injuring several postal workers, and committed a series of arsons that killed at least five people and injured at least 24. When imprisoned, the group's members engaged in hunger strikes and were subject to force-feeding. Emmeline Pankhurst said the group's goal was "to make England and every department of English life insecure and unsafe." The WSPU is also noted for its participation in the White Feather Campaign, a practice of handing out white feathers to emasculate men into joining the WW1 war effort.

The Wuchang Uprising was an armed rebellion against the ruling Qing dynasty that took place in Wuchang (now Wuchang District of Wuhan) in the Chinese province of Hubei on 10 October 1911, beginning the 1911 Revolution that successfully overthrew China's last imperial dynasty, the Qing dynasty. It was led by elements of the New Army, influenced by revolutionary ideas from Tongmenghui. The uprising and the eventual revolution led to the downfall of the Qing dynasty after almost three centuries of imperial rule and the establishment of the Republic of China (ROC). Taiwan commemorates the anniversary of the uprising's outbreak on 10 October as the National Day of the Republic of China. The uprising originated from popular unrest about a railway crisis, and the planning process took advantage of the situation. On 10 October 1911, the New Army stationed in Wuchang launched an assault on the residence of the Viceroy of Huguang. The viceroy, Ruicheng, quickly fled from the residence, and the revolutionaries soon took control of the entire city.

Thomas Woodrow Wilson (December 28, 1856 – February 3, 1924) was the 28th president of the United States, serving from 1913 to 1921. He was the only Democrat to serve as president during the Progressive Era, when Republicans dominated the presidency and legislative branches. As president, Wilson made significant economic reforms and led the United States through World War I. He was the leading architect of the League of Nations, and his stance on foreign policy came to be known as Wilsonian idealism. Born in Staunton, Virginia, Wilson grew up in the Southern United States during the American Civil War and Reconstruction era. After earning a PhD in history and political science from Johns Hopkins University, Wilson taught at several colleges prior to being appointed president of Princeton University, where he emerged as a prominent spokesman for progressivism in higher education. Wilson is considered one of the founding fathers of the field of public administration due to his 1887 article "The Study of Administration". Wilson served as the governor of New Jersey from 1911 to 1913, during which he broke with party bosses and won the passage of several progressive reforms. In the 1912 election, Wilson defeated the incumbent Republican president, William Howard Taft, and the third-party nominee and former president Theodore Roosevelt, becoming the first Southerner to win the presidency since Zachary Taylor in the 1848 election. During his first year as president, Wilson authorized the widespread imposition of racial segregation inside the federal bureaucracy, and his opposition to women's suffrage drew protests. His first term was largely devoted to pursuing the passage of his progressive New Freedom domestic agenda. His first major priority was the Revenue Act of 1913, which began the modern income tax, and the Federal Reserve Act, which created the Federal Reserve System. At the outbreak of World War I in 1914, the U.S. declared neutrality as Wilson tried to negotiate peace between the Allied and Central Powers. Wilson was narrowly re-elected in the 1916 election, defeating Republican nominee Charles Evans Hughes. In April 1917, Wilson asked Congress for a declaration of war against Germany in response to its policy of unrestricted submarine warfare that sank American merchant ships. Wilson concentrated on diplomacy, issuing the Fourteen Points that the Allies and Germany accepted as a basis for post-war peace. He wanted the off-year elections of 1918 to be a referendum endorsing his policies but instead the Republicans took control of Congress. After the Allied victory in November 1918, Wilson attended the Paris Peace Conference. Wilson successfully advocated for the establishment of a multinational organization, the League of Nations, which was incorporated into the Treaty of Versailles that he signed; back home, he rejected a Republican compromise that would have allowed the Senate to ratify the Versailles Treaty and join the League. Wilson had intended to seek a third term in office but had a stroke in October 1919 that left him incapacitated. His wife and his physician controlled Wilson, and no significant decisions were made. Meanwhile, his policies alienated German- and Irish-American Democrats and the Republicans won a landslide in the 1920 election. In February 1924, he died at age 67. Into the 21st century, historians have criticized Wilson for supporting racial segregation, although they continue to rank Wilson as an above-average president for his accomplishments in office. Conservatives in particular have criticized him for expanding the federal government, while others have praised him decreasing the power of large corporations and have credited him for establishing modern liberalism.

RMS Leinster was an Irish ship operated by the City of Dublin Steam Packet Company. She served as the Kingstown-Holyhead mailboat until she was torpedoed and sunk by the German submarine UB-123 on 10 October 1918, while bound for Holyhead. She sank just outside Dublin Bay at a point 4 nautical miles (7.4 km; 4.6 mi) east of the Kish light. The exact number of dead is unknown but researchers from the National Maritime Museum of Ireland believe it was at least 564, which would make it the largest single loss of life in the Irish Sea.

The Carinthian plebiscite (German: Kärntner Volksabstimmung, Slovene: Koroški plebiscit) was held on 10 October 1920 in the area in southern Carinthia predominantly settled by Carinthian Slovenes. It determined the final border between the Republic of Austria and the newly formed Kingdom of Serbs, Croats and Slovenes (Yugoslavia) after World War I. The predominantly Slovene-speaking plebiscite area voted to remain part of Austria with a 59% majority.

Chiang Kai-shek (; 31 October 1887 – 5 April 1975) was a Chinese military commander, revolutionary, and statesman who was President of the Republic of China from 1948 to 1975 and the head of the Nationalist government from 1925 to 1948. As the de facto leader of the Republic of China (ROC), he ruled the country through World War II and oversaw the relocation of its government to Taiwan following defeat in the Chinese Civil War. Born in Zhejiang, Chiang received a military education in China and Japan, joined Sun Yat-sen's Tongmenghui in 1908, and, after the 1911 Revolution, participated in the National Protection War. In 1923, he was appointed by Sun as chief of staff of the Army and Navy Marshal stronghold, and served as commandant of the Whampoa Military Academy from 1924 until its closure in 1930. After Sun's death, Chiang wrested control of the party and National Revolutionary Army from Wang Jingwei in the Canton Coup. From 1926 to 1928, Chiang led the Northern Expedition and largely unified China under a Nationalist government based in Nanjing. He broke the First United Front by purging Chinese Communist Party (CCP) members in the Shanghai massacre, triggering the Chinese Civil War. During the Nanjing decade, Chiang pursued modernization of China while prioritizing the suppression of the Communists over confrontation with Japan following the latter's invasion of Manchuria. The Xi'an Incident in 1936 forced him to form a Second United Front with the CCP against Japan. Between 1937 and 1945, Chiang led China in the Second Sino-Japanese War, mostly from the wartime capital of Chongqing, resulting in a victory for the National Revolutionary Army. In 1943, Chiang attended the Cairo Conference to discuss the terms of Japan's surrender, including the retrocession of Taiwan, after which he suppressed the February 28 incident. When World War II ended, the Chinese Civil War resumed. In 1949, Chiang's KMT was defeated by Mao Zedong's CCP and retreated to Taiwan. He imposed martial law and White Terror on the island that lasted until 1987 and 1992, respectively. Beginning in 1948, he was re-elected five times by the same Eternal Parliament with six-year terms as the president of the ROC, the head of a de facto one-party state, for 25 years until his death. Chiang presided over land reform, economic growth, and the Taiwan Strait crises twice in 1954–1955 and in 1958. Taiwan also pursued an ultimately unsuccessful nuclear weapons programme. Chiang was considered the legitimate leader of China by the United Nations until 1971, when the ROC's seat in the Security Council was transferred to the People's Republic of China. Chiang is a controversial figure. Supporters credit him with unifying the nation and ending the century of humiliation, leading the resistance against Japan, fostering economic development and preserving Chinese culture in contrast to Mao's Cultural Revolution. He is also credited with safeguarding the Forbidden City's treasures during the wars, a substantial portion now housed at the Taipei Palace Museum. Critics fault him for his early appeasement of Japan, the deliberate flooding of the Yellow River, cronyism and corruption linked to the four big families, and authoritarian rule on both mainland China and Taiwan.

United Air Lines Flight 23 was a regularly scheduled flight operated by United Air Lines between Newark, New Jersey, and Oakland, California, with intermediate stops. On October 10, 1933, the Boeing 247 airliner serving the flight—registered as NC13304—exploded and crashed near Chesterton, Indiana, United States, en route from Cleveland to Chicago. It carried three crew and four passengers. All aboard died in the incident, which was caused by an on-board explosive device. Eyewitnesses on the ground reported hearing an explosion shortly after 9 pm and seeing the aircraft in flames at an altitude around 1,000 feet (300 m). A second explosion followed after the aircraft crashed. The crash site was adjacent to a gravel road about 5 miles (8 km) outside of Chesterton, centered in a wooded area on the Jackson Township farm of James Smiley.

A coup d'état, or simply a coup, is typically an illegal and overt attempt by a military organization or other government elites to unseat an incumbent person or leadership. A self-coup is said to take place when a leader, having come to power through legal means, tries to stay in power through illegal means.

The Munich Agreement was reached in Munich on 30 September 1938, by Nazi Germany, the United Kingdom, France, and Italy. The agreement provided for the German annexation of part of the First Czechoslovak Republic called the Sudetenland, where three million people, mainly ethnic Germans, lived. The pact is known in some areas as the Munich Dictate (Czech: Mnichovský diktát; Slovak: Mníchovský diktát), or the Munich Betrayal (Czech: Mnichovská zrada; Slovak: Mníchovská zrada), because of a previous 1924 alliance agreement and a 1925 military pact between France and the Czechoslovak Republic. Germany had started a low-intensity undeclared war on Czechoslovakia on 17 September 1938. In reaction, Britain and France on 20 September formally requested Czechoslovakia cede the Sudetenland territory to Germany. This was followed by Polish and Hungarian territorial demands brought on 21 and 22 September, respectively. Meanwhile, German forces conquered parts of the Cheb District and Jeseník District, where battles included use of German artillery, Czechoslovak tanks, and armored vehicles. Lightly armed German infantry briefly overran other border counties before being repelled. Poland grouped its army units near its common border with Czechoslovakia and conducted an unsuccessful probing offensive on 23 September. Hungary moved its troops towards the border with Czechoslovakia, without attacking. The Soviet Union announced its willingness to come to Czechoslovakia's assistance, provided the Red Army would be able to cross Polish and Romanian territory; both countries refused. An emergency meeting of the main European powers—not including Czechoslovakia, although their representatives were present in the town, nor the Soviet Union, an ally to France and Czechoslovakia—took place in Munich, on 29–30 September. An agreement was quickly reached on Adolf Hitler's terms, and signed by the leaders of Germany, France, Britain, and Italy. The Czechoslovak mountainous borderland marked a natural border between the Czech state and the Germanic states since the early Middle Ages; it also presented a major natural obstacle to a possible German attack. Strengthened by border fortifications, the Sudetenland was of absolute strategic importance to Czechoslovakia. On 30 September, president Beneš submitted to the combination of military pressure by Germany, Poland, and Hungary, and diplomatic pressure by Britain and France, and agreed to surrender territory to Germany following the Munich terms. The Munich Agreement was soon followed by the First Vienna Award on 2 November 1938, separating largely Hungarian inhabited territories in southern Slovakia and southern Subcarpathian Rus' from Czechoslovakia. On 30 November, Czechoslovakia ceded to Poland small patches of land in the Spiš and Orava regions. In March 1939, the First Slovak Republic, a German puppet state, proclaimed its independence. Shortly afterwards, Hitler reneged on his promise to respect the integrity of Czechoslovakia by occupying the remainder of the country and creating the Protectorate of Bohemia and Moravia. The conquered nation's armaments industry and tanks and its large army allowed Germany to strengthen. Much of Europe celebrated the Munich Agreement, as they considered it a way to prevent a major war on the continent. Hitler announced that it was his last territorial claim in Northern Europe. Today, the Munich Agreement is regarded as a failed act of appeasement, and the term has become "a byword for the futility of appeasing expansionist totalitarian states".

The Double Tenth Agreement, formally known as the Summary of Conversations Between the Government and Representatives of the Communist Party of China, was a pact between the Kuomintang-ruled Nationalist government (KMT) and the Chinese Communist Party (CCP). The agreement was concluded on 10 October 1945, the Double Ten Day of the Republic of China (ROC), following 43 days of talks known as the Chongqing Negotiations (Chinese: 重慶談判). Held in Chongqing, China, from 29 August to 10 October 1945, the negotiations were highlighted by a meeting between CCP Chairman Mao Zedong and KMT Chairman Chiang Kai-shek, marking the first time the two leaders had met in 20 years. It would also be their final meeting. Mao and United States Ambassador to China Patrick J. Hurley had flown together to Chongqing on 27 August to initiate the talks, though most of the subsequent negotiations were undertaken by Wang Shijie and Zhou Enlai, representing the KMT and the CCP, respectively. The outcome of the agreement was that the CCP acknowledged the KMT as the legitimate government, while the KMT in return recognized the CCP as a legitimate opposition party. Additionally, the Shangdang Campaign, an ongoing military conflict that had begun on 10 September, came to an end on 12 October as a result of the agreement's announcement. The document was formally signed at what is now the Red Rock Village Museum in Chongqing.

Muscat and Oman, officially known as the Sultanate of Muscat and Oman, also known briefly as the State of Muscat and Oman during the rule of Taimur bin Faisal, was a state that was under de facto British protection which existed in the second half of the 19th century and 20th century. It encompassed the present-day Sultanate of Oman and parts of present-day United Arab Emirates and Pakistan.

Dwight David "Ike" Eisenhower (born David Dwight Eisenhower; October 14, 1890 – March 28, 1969) was the 34th president of the United States, serving from 1953 to 1961. In his previous military career, he commanded the Allied Expeditionary Force during World War II, including in Operation Torch in North Africa and Operation Overlord on D-Day in Normandy. For his distinguished service in the U.S. Army, Eisenhower was honored with the five-star rank of General of the Army. Eisenhower graduated from West Point in 1915. During World War I, he was denied a request to serve in Europe and instead commanded a unit that trained tank crews. Between the wars he served in staff positions in the US and the Philippines, reaching the rank of brigadier general shortly before the entry of the US into World War II in 1941. After further promotion Eisenhower oversaw the Allied invasions of North Africa and Sicily before supervising the invasions of France and Germany. After the war ended in Europe, he served as military governor of the American-occupied zone of Germany (1945), as Army Chief of Staff (1945–1948), president of Columbia University (1948–1953), and as the first supreme commander of NATO (1951–1952). In 1952, Eisenhower entered the presidential race as a Republican, in part to block the presidential prospects of Senator Robert A. Taft, who opposed NATO and sought to undo the New Deal. Eisenhower won that year's election and the 1956 election in landslides, both times defeating Adlai Stevenson II. Eisenhower's main goals in office were to contain the spread of communism and reduce federal deficits. In 1953, Eisenhower considered using nuclear weapons to end the Korean War and may have threatened China with nuclear attack if an armistice was not reached quickly. China did agree and an armistice resulted, which remains in effect. His New Look policy of nuclear deterrence prioritized "inexpensive" nuclear weapons while reducing funding for expensive Army divisions. He continued Harry S. Truman's policy of recognizing Taiwan as the legitimate government of China, and he won congressional approval of the Formosa Resolution. His administration provided aid to help the French try to fight Vietnamese Communists in the First Indochina War. After the French left, he gave strong financial support to the new state of South Vietnam. Eisenhower supported regime-changing military coups in Iran and Guatemala orchestrated by his own administration. During the Suez Crisis of 1956, he condemned the Israeli, British, and French invasion of Egypt, and he forced them to withdraw. He also condemned the Soviet invasion during the Hungarian Revolution of 1956 but took no action. He deployed 15,000 soldiers during the 1958 Lebanon crisis. Near the end of his term, a summit meeting with the Soviet leader Nikita Khrushchev was cancelled when a US spy plane was shot down over the Soviet Union. Eisenhower approved the Bay of Pigs Invasion, which was left to John F. Kennedy to carry out. Eisenhower continued New Deal agencies and expanded Social Security. He covertly opposed Joseph McCarthy and contributed to the end of McCarthyism by openly invoking executive privilege. He signed the Civil Rights Act of 1957 and sent Army troops to enforce federal court orders which integrated schools in Little Rock, Arkansas. His administration undertook the development and construction of the Interstate Highway System, which remains the largest construction of roadways in American history. In 1957, following the Soviet launch of Sputnik, Eisenhower led the American response which included the creation of NASA and the establishment of a stronger, science-based education via the National Defense Education Act. The Soviet Union began to reinforce their own space program, escalating the Space Race. His two terms saw unprecedented economic prosperity except for a minor recession in 1958. In his farewell address, he expressed his concerns about the dangers of massive military spending, particularly deficit spending and government contracts to private military manufacturers, which he dubbed "the military–industrial complex". Historical evaluations of his presidency place him among the upper tier of US presidents.

The Windscale fire of 10 October 1957 was the worst nuclear accident in the United Kingdom's history, ranked in severity at level 5 out of 7 on the International Nuclear Event Scale. The fire was in Unit 1 of the two-pile Windscale site (now Sellafield) on the north-west coast of England in Cumberland. The two graphite-moderated reactors, referred to at the time as "piles", had been built as part of the British post-war atomic bomb project. Windscale Pile No. 1 was operational in October 1950, followed by Pile No. 2 in June 1951. The fire burned for three days and released radioactive fallout which spread across the UK and the rest of Europe. The radioactive isotope iodine-131, which may lead to cancer of the thyroid, was of particular concern at the time. It has since come to light that small but significant amounts of the highly dangerous radioactive isotope polonium-210 were also released. Calculations based on the amount of radiation released estimate that the accident may have caused 190 cases of cancer, with around 100 of these being fatal, however recent epidemiological studies failed to find any such increase. At the time of the incident, no one was evacuated from the surrounding area, but milk from about 500 km2 (190 square miles) of the nearby countryside was destroyed for about a month afterward due to concerns about it being contaminated with iodine-131. The UK government played down the events at the time, and reports on the fire were subject to heavy censorship, as Prime Minister Harold Macmillan feared the incident would harm British–American nuclear relations. The event was not an isolated incident; there had been a series of radioactive discharges from the piles in the years leading up to the accident. In early 1957, there had been a leak of radioactive material in which strontium-90 was released into the environment. Like the later fire, this incident was covered up by the British government. Later studies on the release of radioactive material due to the Windscale fire revealed that much of the contamination had resulted from such radiation leaks before the fire. A 2010 study of workers involved in the cleanup of the accident found no significant long-term health effects from their involvement.

Bizerte or Bizerta ( biz-UR-tə; Arabic: بنزرت, romanized: Binzart, Tunisian Arabic pronunciation: [bɪnˈzart] ) is the capital and largest city of Bizerte Governorate in northern Tunisia. It is the northernmost city in Africa, located 65 km (40 mi) north of the capital Tunis. It is also known as the last town to remain under French control after the rest of the country won its independence from France. The city had 162,053 inhabitants in 2014.

The Partial Test Ban Treaty (PTBT), formally known as the 1963 Treaty Banning Nuclear Weapon Tests in the Atmosphere, in Outer Space and Under Water, prohibited all test detonations of nuclear weapons except for those conducted underground. It is also abbreviated as the Limited Test Ban Treaty (LTBT) and Nuclear Test Ban Treaty (NTBT), though the latter may also refer to the Comprehensive Nuclear-Test-Ban Treaty (CTBT), which succeeded the PTBT for ratifying parties. Negotiations initially focused on a comprehensive ban, but that was abandoned because of technical questions surrounding the detection of underground tests and Soviet concerns over the intrusiveness of proposed verification methods. The impetus for the test ban was provided by rising public anxiety over the magnitude of nuclear tests, particularly tests of new thermonuclear weapons (hydrogen bombs), and the resulting nuclear fallout. A test ban was also seen as a means of slowing nuclear proliferation and the nuclear arms race. Though the PTBT did not halt proliferation or the arms race, its enactment did coincide with a substantial decline in the concentration of radioactive particles in the atmosphere. The PTBT was signed by the governments of the Soviet Union, the United Kingdom, and the United States in Moscow on 5 August 1963 before it was opened for signature by other countries. The treaty formally went into effect on 10 October 1963. Since then, 123 other states have become party to the treaty. Ten states have signed but not ratified the treaty. The treaty contributed to a lasting taboo on non-underground tests. Non-signatories France and China continued atmospheric testing until 1974 and 1980. Signatories Israel and South Africa may have violated it with the 1979 Vela incident. Since 1980, all declared nuclear weapons states have made underground tests, and there have been no suspected non-underground tests.

The 1964 Summer Olympics, officially the Games of the XVIII Olympiad and commonly known as Tokyo 1964, were an international multi-sport event held from 10 to 24 October 1964 in Tokyo, Japan. Tokyo had been awarded the organization of the 1940 Summer Olympics, but this honor was subsequently passed to Helsinki due to Japan's invasion of China, before ultimately being cancelled due to World War II. The 1964 Summer Olympics in Tokyo were the first Olympic Games held in the city and, as of 2021, the only ones to have spectators, as the 2020 Summer Olympics in Tokyo were conducted without spectators due to the COVID-19 pandemic. Tokyo was chosen as the host city during the 55th IOC Session in West Germany on 26 May 1959. The 1964 Summer Games were the first Olympics held in Asia, and marked the first time South Africa was excluded for using its apartheid system in sports. Until 1960, South Africa had fielded segregated teams, conforming to the country's racial classifications; for the 1964 Games the International Olympic Committee demanded a multi-racial delegation to be sent, and after South Africa refused, they were excluded from participating. The country was, however, allowed to compete at the 1964 Summer Paralympics, also held in Tokyo, its Paralympic Games debut. The 1964 Games were also the first to be telecast internationally without the need for tapes to be flown overseas, as they had been for the 1960 Olympics four years earlier. The games were telecast to the United States using Syncom 3, the first geostationary communication satellite, and from there to Europe using Relay 1. These were also the first Olympic Games to have color telecasts, albeit partially. Certain events such as the sumo wrestling and judo matches, sports popular in Japan, were tried out using Toshiba's new colour transmission system, but only for the domestic market. The entire 1964 Olympic Games was chronicled in the ground-breaking 1965 sports documentary film Tokyo Olympiad, directed by Kon Ichikawa. The games were scheduled for mid-October to avoid the city's midsummer heat and humidity and the September typhoon season. The previous Olympics in Rome in 1960 started in late August and experienced hot weather. The following games in 1968 in Mexico City also began in October. The 1964 Olympics were also the last to use a traditional cinder track for the track events. Since 1968, a smooth, synthetic, all-weather track has been used. The United States topped the gold medal table at these Games, while the Soviet Union won the most medals overall. In 2021, due to delay over the COVID-19 pandemic, Tokyo hosted the 2020 Summer Olympics, making it the first city in Asia to host the Summer Olympic Games twice. Japan also hosted the Winter Olympics twice with the Sapporo 1972 and Nagano 1998 games.

The Outer Space Treaty, formally called the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies, is a multilateral treaty that forms the basis of international space law.

Fiji, officially the Republic of Fiji, is an archipelagic country in Melanesia, part of Oceania in the South Pacific Ocean. It lies about 1,100 nautical miles north-northeast of New Zealand. Fiji consists of an archipelago of more than 330 islands—of which about 110 are permanently inhabited—and more than 500 islets, amounting to a total land area of about 18,300 square kilometres (7,100 sq mi). The most outlying island group is Ono-i-Lau. About 87% of the total population live on the two major islands, Viti Levu and Vanua Levu. About three-quarters of Fijians live on Viti Levu's coasts, either in the capital city of Suva, or in smaller urban centres such as Nadi or Lautoka. The interior of Viti Levu is sparsely inhabited because of its terrain.

The October Crisis was a chain of political events in Canada that started in October 1970 when members of the Front de libération du Québec (FLQ) kidnapped the provincial Labour Minister Pierre Laporte and British diplomat James Cross from his Montreal residence. These events saw Prime Minister Pierre Trudeau invoking the War Measures Act for the first time in Canadian history during peacetime. Laporte was assassinated over the course of the crisis.

The plant is owned and operated by Teollisuuden Voima (TVO), and is located on Olkiluoto Island, on the shore of the Gulf of Bothnia, in the municipality of Eurajoki in western Finland, about 20 kilometres (12 mi) from the town of Rauma and about 50 kilometres (31 mi) from the city of Pori.

The 1980 El Asnam earthquake occurred on October 10 at 13:25:23 local time with a moment magnitude of 7.1 and a maximum Mercalli intensity of X (Extreme). The shock occurred in the Algerian town of El Asnam. The shocks were felt over 550 km (340 mi) away, with the initial earthquake lasting 35 seconds. It was the largest earthquake in Algeria, and was followed three hours later by a magnitude 6.2 aftershock. The earthquake created about 42 km (26 mi) of surface rupture and had a vertical slip of up to 4.2 m (14 ft). No foreshocks were recorded. The earthquake was found to have occurred very close to the epicenter of the 1954 Chlef earthquake using joint epicenter determination techniques. It occurred at a previously unknown reverse fault.

The Achille Lauro hijacking took place on 7 October 1985, when the Italian ocean liner MS Achille Lauro was hijacked by four men representing the Palestinian Liberation Front (PLF) off the coast of Egypt, as she was sailing from Alexandria to Ashdod, Israel. A 69-year-old Jewish-American man in a wheelchair, Leon Klinghoffer, was murdered by the hijackers and thrown overboard. The hijacking sparked the "Sigonella Crisis".

The 1986 San Salvador earthquake occurred at 11:49:26 local time on 10 October 1986 with a moment magnitude of 5.7 and a maximum Mercalli intensity of IX (Violent). The shock caused considerable damage to El Salvador's capital city of San Salvador and surrounding areas, including neighboring Honduras and Guatemala.

Austral Líneas Aéreas Flight 2553 was an Argentine domestic scheduled passenger flight from Posadas to Buenos Aires. On October 10, 1997, the McDonnell Douglas DC-9-32 that was operating the flight crashed on the lands of Estancia Magallanes, Nuevo Berlín, 32 kilometres away from Fray Bentos, Uruguay. All 74 passengers and crew died upon impact. The accident remains the deadliest in Uruguayan history.

Lignes Aériennes Congolaises (LAC) was the flag carrier of the Democratic Republic of the Congo. It was established in 1997 to succeed the folded Air Zaïre. Halting operations in 1999, it was reactivated for a short period in 2002, only to fold operations permanently in 2003.

The Iraq War, also referred to as the Second Gulf War, was a protracted armed conflict in Iraq from 2003 to 2011. It began with the invasion by a United States–led coalition, which resulted in the overthrow of the Ba'athist government of Saddam Hussein. During the US occupation of Iraq, the conflict persisted as an insurgency that arose against coalition forces and the newly established Iraqi government. US forces were officially withdrawn in 2011. In 2014, the US became re-engaged in Iraq, leading a new coalition under Combined Joint Task Force – Operation Inherent Resolve, as the conflict evolved into the ongoing Islamic State insurgency.

The Netherlands Antilles, also known as the Dutch Antilles, was a constituent Caribbean country of the Kingdom of the Netherlands consisting of the islands of Saba, Sint Eustatius, and Sint Maarten in the Lesser Antilles, and Aruba, Bonaire, and Curaçao in the Leeward Antilles. The country came into being in 1954 as the autonomous successor of the Dutch colony of Curaçao and Dependencies, and it was dissolved in 2010, when Aruba, Sint Maarten and Curaçao gained the status of constituent countries within the Kingdom of the Netherlands, and Saba, Sint Eustatius, and Bonaire gained the status of special municipalities of the Netherlands as the Caribbean Netherlands. The neighboring Dutch colony of Surinam, in continental South America, did not become part of the Netherlands Antilles but became a separate sovereign country in 1954. All the territories that formerly belonged to the Netherlands Antilles remain part of the Kingdom of the Netherlands today, although the legal status of each island differs. As a group they are still commonly called the Dutch Caribbean, regardless of their legal status.

On 10 October 2015 at 10:04 local time (EEST) in Ankara, the capital city of Turkey, two bombs were detonated outside Ankara Central railway station. With a death toll of 109 civilians, the attack surpassed the 2013 Reyhanlı bombings as the deadliest terror attack in Turkish history. Another 500 people were injured. Censorship monitoring group Turkey Blocks identified nationwide slowing of social media services in the aftermath of the blasts, described by rights group Human Rights Watch as an "extrajudicial" measure to restrict independent media coverage of the incident.

Hurricane Michael was a powerful and destructive tropical cyclone that became the first Category 5 hurricane to make landfall in the contiguous United States since Andrew in 1992. It was the third-most intense Atlantic hurricane to make landfall in the contiguous United States in terms of pressure, behind the 1935 Labor Day hurricane and Hurricane Camille in 1969. Michael was the first Category 5 hurricane on record to impact the Florida Panhandle, the fourth-strongest landfalling hurricane in the contiguous United States in terms of wind speed, and the most intense hurricane on record to strike the United States in the month of October.
