August 21 in History

The American Revolutionary War, also known as the Revolutionary War or American War of Independence, 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 led King George III and 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.

On August 21, 1883, a violent and devastating tornado affected southeastern portions of the U.S. state of Minnesota. The massive tornado, retrospectively estimated to have been an F5 on the modern Fujita scale, caused at least 37 deaths and over 200 injuries. The tornado was part of a tornado family, a series of tornadoes produced by a supercell, that included at least two significant tornadoes across Southeast Minnesota on August 21. A third significant tornado occurred two hours before the main event hit Rochester. The Rochester tornado indirectly led to the formation of Saint Mary's Hospital, now part of the Mayo Clinic. The tornado closely followed destructive tornadoes a month earlier in the same area: on July 21, two significant, deadly tornadoes hit the area, including an F4 tornado family that killed four people in Dodge and Olmsted Counties, especially near Dodge Center.

Operation Tractable was the final attack conducted by Canadian and Polish troops, supported by a British tank brigade, during the Battle of Normandy during World War II.

This operation was undertaken by the First Canadian Army with the 1st Polish Armoured Division and a British armoured brigade against Army Group B of the Westheer in what became the largest encirclement on the Western Front during the Second World War. Despite a slow start and limited gains north of Falaise, novel tactics by the 1st Polish Armoured Division during the drive for Chambois enabled the Falaise Gap to be partially closed by 19 August 1944, trapping about 150,000 German soldiers in the Falaise Pocket.

The Xá Lợi Pagoda raids were a series of synchronized attacks on various Buddhist pagodas in the major cities of South Vietnam shortly after midnight on 21 August 1963. The raids were executed by the Army of the Republic of Vietnam Special Forces under Colonel Lê Quang Tung and combat police, both of which took their orders directly from Ngô Đình Nhu, the younger brother of the Roman Catholic President Ngô Đình Diệm. Xá Lợi Pagoda, the largest pagoda in the South Vietnamese capital Saigon was the most prominent of the raided temples. Over 1,400 Buddhists were arrested, and estimates of the death toll and missing ranged up to the hundreds. In response to the Huế Vesak shootings and a ban on the Buddhist flag in early May, South Vietnam's Buddhist majority rose in widespread civil disobedience and protest against the religious bias and discrimination of the Catholic-dominated Diệm government. Buddhist temples in major cities, most prominently the Xá Lợi pagoda, became focal points for protesters and assembly points for Buddhist monks from rural areas.

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.

The 1991 Soviet coup attempt, also known as the August Coup, was a failed attempt by hardliners of the Communist Party of the Soviet Union (CPSU) to forcibly seize control of the country from Mikhail Gorbachev, who was Soviet president and General Secretary of the CPSU at the time. The coup leaders consisted of top military and civilian officials, including Vice President Gennady Yanayev, who together formed the State Committee on the State of Emergency. They opposed Gorbachev's reform program, were angry at the loss of control over Eastern European states and fearful of the New Union Treaty, which was on the verge of being signed by the Soviet Union (USSR). The treaty was to decentralize much of the central Soviet government's power and distribute it among its fifteen republics. Boris Yeltsin's demand for more autonomy to the republics opened a window for the plotters to organize the coup.
