December 9 in History

The Gothic War between the Eastern Roman Empire during the reign of Emperor Justinian I and the Ostrogothic Kingdom of Italy took place from 535 to 554 in the Italian Peninsula, Dalmatia, Sardinia, Sicily, and Corsica. It was one of the last of the many Gothic wars against the Byzantine Empire. The war had its roots in Justinian's ambition to recover the provinces of the former Western Roman Empire, which had been lost to invading barbarian tribes during the Migration Period.

Švitrigaila was Grand Duke of Lithuania from 1430 to 1432. He spent most of his life in largely unsuccessful dynastic struggles against his cousins Vytautas and Sigismund Kęstutaitis.

The Qing dynasty, officially the Great Qing, also known as the Qing Empire or Qing China, was a Manchu-led imperial dynasty of China and an early modern empire in East Asia which existed from 1636/1644 to 1912. The last imperial dynasty in Chinese history, the Qing dynasty was preceded by the Ming dynasty and succeeded by the Republic of China. At the height of its power, the empire stretched from the Sea of Japan in the east to the Pamir Mountains in the west, and from the Mongolian Plateau in the north to the South China Sea in the south. Originally emerging from the Later Jin dynasty founded in 1616 and proclaimed in Shenyang in 1636, the dynasty seized control of the Ming capital Beijing and North China in 1644, traditionally considered the start of the dynasty's rule. The dynasty lasted until the Xinhai Revolution of October 1911 led to the abdication of the last emperor in February 1912. The multi-ethnic Qing dynasty assembled the territorial base for modern China. The Qing controlled the most territory of any dynasty in Chinese history, and in 1790 was the fourth-largest empire in world history to that point. It was also the most populous state at the time, with over 426 million citizens in 1907.

Augustin-Jean Fresnel was a French civil engineer and physicist whose research in optics led to the almost unanimous acceptance of the wave theory of light, fully supplanting Newton's corpuscular theory, from the late 1830s  until the end of the 19th century. He is perhaps better known for inventing the catadioptric (reflective/refractive) Fresnel lens and for pioneering the use of "stepped" lenses to extend the visibility of lighthouses, saving countless lives at sea. The simpler dioptric stepped lens, first proposed by Count Buffon  and independently reinvented by Fresnel, is used in screen magnifiers and in condenser lenses for overhead projectors.

The Texas Revolution was a rebellion by Anglo-American immigrants as well as Hispanic Texans against the centralist government of Mexico in the Mexican state of Coahuila y Tejas. Although the uprising was part of a larger revolt that included other provinces opposed to the regime of President Miguel Barragán and General Antonio López de Santa Anna, the Mexican government believed the United States had instigated the Texas insurrection with the goal of annexation. The Mexican Congress passed the Tornel Decree, declaring that any foreigners fighting against Mexican troops "will be deemed pirates and dealt with as such, being citizens of no nation presently at war with the Republic and fighting under no recognized flag". Only the province of Texas succeeded in breaking with Mexico, establishing the Republic of Texas. It was eventually annexed by the United States about a decade later.

The National Assembly bombing was a bomb attack carried out on 9 December 1893 in Paris by the anarchist militant Auguste Vaillant. Acting in reaction to other events of the Ère des attentats, literally, "Era of Attacks", (1892–1894), such as the execution of Ravachol, the militant carefully prepared a bomb and managed to enter the galleries of the French National Assembly. He then threw it towards the deputies but was hindered by the arm of another spectator, which caused his attempt to fail. The bomb exploded, killing no one but slightly injuring several people – including Vaillant himself. The session at the National Assembly continued without interruption after the attack, while Vaillant was arrested later that day.

The Cross Mountain Mine disaster was a coal mine explosion that occurred on December 9, 1911, near the community of Briceville, Tennessee, in the southeastern United States. In spite of a well-organized rescue effort led by the newly created Bureau of Mines, 84 miners died in the disaster. The cause of the explosion was the ignition of dust and methane gas released by a roof fall. Miners would use open oil lamps to provide a light source down in the mines.

The Kingdom of Romania was a constitutional monarchy that existed from 25 March [O.S. 13 March] 1881 with the crowning of prince Karl of Hohenzollern-Sigmaringen as King Carol I, until 30 December 1947 with the abdication of King Michael I and the Romanian Parliament proclamation of the Romanian People's Republic.

The Second Sino-Japanese War, known in China as the War of Resistance Against Japan, was fought between the Republic of China and the Empire of Japan and its puppet states between 1937 and 1945, following a period of war 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.

The Republic of China established its governance over Mainland China on 1 January 1912 following the Xinhai Revolution, which overthrew the Manchu-led Qing dynasty and ended China's imperial history. The Beiyang government in Beijing was the internationally recognized government of the ROC from 1912 to 1928, with regional warlords occupying parts of the country after the death of Beiyang leader Yuan Shikai in 1916. In 1926, the Kuomintang (KMT) launched the Northern Expedition, which eventually reunified the country in 1928. The KMT established the Nationalist government and governed the ROC as a one-party state with Nanjing as the capital. In 1949, the KMT was defeated in the Chinese Civil War by the Chinese Communist Party (CCP) and the ROC government retreated to Taiwan, where it remains to this date. The ROC is recorded as a founding member of both the League of Nations and the United Nations. It claimed 11.4 million km2 (4.4 million sq mi) of territory, and its population of 541 million in 1949 made it the most populous country in the world.

The Constituent Assembly of India was the legislature of the Dominion of India from its independence in August 1947 until 1950, when India became a republic.

The Cold War was a period of international geopolitical rivalry between the United States (US) and the Soviet Union (USSR) and their respective allies, the capitalist Western Bloc and communist Eastern Bloc. It began in the aftermath of the Second World War and ended with the dissolution of the Soviet Union in 1991. The term cold war is used because there was no direct fighting between the two superpowers, though each supported opposing sides in regional conflicts known as proxy wars. In addition to the struggle for ideological and economic influence and an arms race in both conventional and nuclear weapons, the Cold War was expressed through technological rivalries such as the Space Race, espionage, propaganda campaigns, embargoes, and sports diplomacy.

Trans-Canada Air Lines Flight 810-9 was a Canadair North Star on a scheduled flight from Vancouver to Calgary. The plane crashed into Mount Slesse near Chilliwack, British Columbia, Canada, on 9 December 1956 after encountering severe icing and turbulence over the mountains. All 62 people on board died, making it one of the deadliest airline crashes ever as of that date; it still ranks as the sixth deadliest air disaster in Canadian history.

The Kecksburg UFO incident occurred on December 9, 1965, at Kecksburg, Pennsylvania, United States, when a fireball was reported by citizens of six U.S. states and Canada over Detroit, Michigan, and Windsor, Ontario. Astronomers said it was likely to have been a meteor bolide burning up in the atmosphere and descending at a steep angle. NASA released a statement in 2005 reporting that experts had examined fragments from the area and determined they were from a Soviet satellite, but that records of their findings were lost in 1987. NASA responded to court orders and Freedom of Information Act requests to search for the records. The incident gained wide notoriety in popular culture and ufology, with speculation ranging from extraterrestrial craft to debris from the Soviet space probe Kosmos 96, and is often called "Pennsylvania's Roswell".

In Canada, topfreedom has primarily been an attempt to combat the interpretation of indecency laws that considered a woman's breasts to be indecent, and therefore their exhibition in public an offence. In British Columbia, it is a historical issue dating back to the 1930s and the public protests against the materialistic lifestyle held by the radical religious sect of the Freedomites, whose pacifist beliefs led to their exodus from Russia to Canada at the end of the 19th century. The Svobodniki became famous for their public nudity: primarily for their nude marches in public and the acts of arson committed also in the nude.

The Space Shuttle program was the fourth human spaceflight program carried out by the U.S. National Aeronautics and Space Administration (NASA), which accomplished routine transportation for Earth-to-orbit crew and cargo from 1981 to 2011. Its official program name was carried over from the 1969 plan for the Space Transportation System (STS) of reusable spacecraft. Only the shuttle and supporting rockets were funded for development; a proposed nuclear lunar shuttle in the plan was canceled in 1972. It flew 135 missions and carried 355 astronauts from 16 countries, many on multiple trips.

Central America is a subregion of North America. Its political boundaries are defined as bordering Mexico to the north, Colombia to the southeast, the Caribbean to the east, and the Pacific Ocean to the southwest. Central America is usually defined as consisting of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama, and also, in specialized contexts, including Mexico. Within Central America is the Mesoamerican biodiversity hotspot, which extends from southern Mexico to southeastern Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, seismic activity in the region, such as volcanic eruptions and earthquakes, is high, which has caused death, injury, and property damage.
