June 22 in History

A volcanic eruption occurs when material is expelled from a volcanic vent or fissure. Several types of volcanic eruptions have been distinguished by volcanologists. These are often named after famous volcanoes where that type of behavior has been observed. Some volcanoes may exhibit only one characteristic type of eruption during a period of activity, while others may display an entire sequence of types all in one eruptive series.

The Chesapeake–Leopard affair was a naval engagement off the coast of Norfolk, Virginia, on June 22, 1807, between the British fourth-rate HMS Leopard and the American frigate USS Chesapeake. The crew of Leopard pursued, attacked, and boarded the American frigate, looking for deserters from the Royal Navy. Chesapeake was caught unprepared and after a short battle involving broadsides received from Leopard, the commander of Chesapeake, James Barron, surrendered his vessel to the British. Chesapeake had fired only one shot.

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 Congress on 17 February 1815.

The United States Department of Justice (DOJ) is an executive department of the United States federal government that oversees the domestic enforcement of federal laws and the administration of justice. It is equivalent to the justice or interior ministries of other countries. The department is headed by the United States attorney general, who reports directly to the president of the United States and is a member of the president's Cabinet. Deputy Attorney General Todd Blanche currently serves as the acting attorney general.

The British Overseas Territories (BOTs) are fourteen dependent territories of the United Kingdom (UK) that lie outside the British Islands. These territories are remnants of the former British Empire, which remained under British sovereignty following decolonisation, albeit with varying constitutional statuses. Britain is notably the only country to still have territories in every continent on earth, except Australia.

The London Underground is a rapid transit system serving Greater London and some parts of the adjacent home counties of Buckinghamshire, Essex, and Hertfordshire in England. It is part of the network of transport services managed by Transport for London.

The Mexican Revolution was an extended sequence of armed regional conflicts in Mexico from 20 November 1910 to 1 December 1920. It has been called "the defining event of modern Mexican history". It saw the destruction of the Federal Army, its replacement by a revolutionary army, and the transformation of Mexican culture and government. The northern Constitutionalist faction prevailed on the battlefield and drafted the present-day Constitution of Mexico, which aimed to create a strong central government. Revolutionary generals held power from 1920 to 1940. The revolutionary conflict was primarily a civil war, but foreign powers, having important economic and strategic interests in Mexico, figured in the outcome of Mexico's power struggles; the U.S. involvement was particularly high. The conflict led to the deaths of around one million people, mostly non-combatants.

Field marshal (FM) has been the highest rank in the British Army since 1736. A five-star rank with NATO code OF-10, it is equivalent to an Admiral of the Fleet in the Royal Navy or a Marshal of the Royal Air Force in the Royal Air Force (RAF). A Field Marshal's insignia consists of two crossed batons surrounded by yellow leaves below the Tudor Crown. Like Marshals of the Royal Air Force and Admirals of the Fleet, Field Marshals traditionally remain officers for life, though on half-pay when not in an appointment or retired. The rank has been used sporadically throughout its history, and was vacant during parts of the 18th and 19th centuries. After the Second World War, it became standard practice to appoint the Chief of the Imperial General Staff to the rank on his last day in the post. Army officers occupying the post of Chief of the Defence Staff, the professional head of all the British Armed Forces, were usually promoted to the rank upon their appointment.

Nazi Germany, officially the German Reich and later the Greater German Reich, was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a totalitarian dictatorship. The Third Reich, meaning "Third Realm" or "Third Empire", referred to the Nazi claim that Nazi Germany was the successor to the Holy Roman Empire (800–1806) and the German Empire (1871–1918). The Third Reich, which the Nazis referred to as the Thousand-Year Reich, ended in May 1945, after 12 years, when the Allies defeated Germany and entered the capital, Berlin, ending World War II in Europe.

The U.S. Pledge of Allegiance is a patriotic recited verse that promises allegiance to the flag of the United States and the republic of the United States. The first version was written in 1885 by Captain George Thatcher Balch, a Union army officer in the Civil War who later wrote a book on how to teach patriotism to children in public schools. In 1892, Francis Bellamy revised Balch's verse as part of a magazine promotion surrounding the World's Columbian Exposition, which celebrated the 400th anniversary of Christopher Columbus' arrival in the Americas.

Franklin Delano Roosevelt, also known as FDR, was the 32nd president of the United States, serving from 1933 until his death in 1945. He is the longest-serving US president and the only one to have served more than two terms. His first two terms were centered on combating the Great Depression, while his third and fourth focused on US involvement in World War II. A member of the Democratic Party, Roosevelt served in the New York State Senate from 1911 to 1913 and as the 44th governor of New York from 1929 to 1932.

HMT Empire Windrush was a passenger motor ship that was launched in Germany in 1930 as the MV Monte Rosa. She was built as an ocean liner for the German shipping company Hamburg Süd. They used the ship to carry German emigrants to South America, and as a cruise ship. During World War II, she was taken over by the German navy and used as a troopship. During the war, she survived two Allied attempts to sink her.

Air France Flight 117 was a multi-leg international scheduled flight from Paris-Orly Airport via Lisbon, the Azores, Guadeloupe and Peru to Santiago, Chile, which crashed on 22 June 1962 killing 113 people.

Buddhism in Vietnam, as practiced by the Vietnamese people, is a form of East Asian Mahayana Buddhism. It is the second largest religion in Vietnam. According to the Vietnamese government's 2019 National Population and Housing Census, approximately 4.6 million individuals identified as Buddhists, representing about 4.8% of the total population at that time. However, the U.S. Department of State's 2023 Report on International Religious Freedom cites Vietnam's "White Book", stating that the Buddhist population increased from nearly 10 million in 2008 to approximately 14 million in 2021, which accounts for 13.3% of the overall population of Vietnam.

Charon, formal designation (134340) Pluto I, is the largest of the five known natural satellites of the dwarf planet Pluto. It has a mean radius of 606 km (377 mi). Charon is a planetary-mass moon and the sixth-largest known trans-Neptunian object after Pluto, Eris, Haumea, Makemake, and Gonggong. It was discovered in 1978 at the United States Naval Observatory in Washington, D.C., using photographic plates taken at the United States Naval Observatory Flagstaff Station (NOFS).

Virgin Atlantic, a trading name of Virgin Atlantic Airways Limited and Virgin Atlantic International Limited, is a British airline with its head office in Crawley, West Sussex, England. The airline was established in 1984 as British Atlantic Airways, and was originally planned by its co-founders Randolph Fields and Alan Hellary to fly between London and the Falkland Islands. Soon after changing the name to Virgin Atlantic Airways, Fields sold his shares in the company to Richard Branson in return for unlimited free travel. Its maiden flight from London–Gatwick to Newark took place on 22 June 1984.

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.

The moment magnitude scale is a measure of an earthquake's magnitude based on its seismic moment. Mw was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori. Similar to the local magnitude/Richter scale (ML ) defined by Charles Francis Richter in 1935, it uses a logarithmic scale; small earthquakes have approximately the same magnitudes on both scales. Despite the difference, news media often use the term "Richter scale" when referring to the moment magnitude scale.

The Washington Metro, often abbreviated as the Metro and formally the Metrorail, is a rapid transit system serving the Washington metropolitan area of the United States. It is administered by the Washington Metropolitan Area Transit Authority (WMATA), which also operates the Metrobus service under the Metro name. Opened in 1976, the network now includes six lines, 98 stations, and 130 miles (210 km) of route.

The Turkish Air Force (TuAF) is the air and space force of the Turkish Armed Forces. It traces its origins to 1 June 1911 when it was founded as the Aviation Squadrons by the Ottoman Empire. It was composed of the Army Aviation Squadrons founded in 1911, and the Naval Aviation Squadrons founded in 1914 which used seaplanes. The Air Force as a branch of the Turkish Armed Forces was founded by the Grand National Assembly of Turkey on 23 April 1920.

A 4.0-kilometre (2.5 mi) deep earthquake measuring a magnitude (Mw ) of 6.2 struck southeastern Afghanistan on 22 June 2022 at 01:24:36 AFT. The earthquake had a maximum Modified Mercalli intensity of IX (Violent). There were between 1,052 to 1,163 deaths and 1,627 to 2,976 injured in Afghanistan and Pakistan. The worst affected provinces in Afghanistan were Paktika, Paktia, Khost, and Nangarhar. Casualties and damage also occurred in Pakistan's Khyber Pakhtunkhwa. At least 10,000 homes collapsed or were severely damaged. The earthquake's shallow hypocenter, proximity to populated areas, and low building quality all contributed to its destructive effects. Shaking was felt over 500 km (310 mi) away by at least 119 million people, including Pakistan's Punjab and parts of India and Iran.
