Mustafa Kemal Atatürk was a Turkish field marshal and statesperson who was the founder of the Republic of Turkey and served as its first president from 1923 until his death in 1938. He led sweeping reforms, turning Turkey into a secular, industrialising nation.

Atatürk's personality cult and the Kemalist historiography developed around it have had significant and ongoing influences on Turkey's political culture and historical narrative.

The Spanish Civil War was fought from 1936 to 1939 between the Republicans and the Nationalist rebels. Republicans loyal to the left-leaning Popular Front government of the Second Spanish Republic included socialists, anarchists, communists, and separatists, supported by the Soviet Union. The opposing Nationalists were an alliance of fascist Falangists, monarchists, conservatives, and traditionalists, supported by Nazi Germany and Fascist Italy. Initially led by a military junta, until General Francisco Franco was appointed supreme leader on 1 October 1936 of what he called the Spanish State. Due to the international political climate at the time, the war was variously viewed as class struggle, religious struggle, or struggle between republican democracy and dictatorship, revolution and counterrevolution, or between fascism and communism. The Nationalists won the war in early 1939, and ruled Spain until Franco's death in November 1975.

USS Greer (DD–145) was a Wickes-class destroyer in the United States Navy, the first ship named for Rear Admiral James A. Greer (1833–1904). In what became known as the "Greer incident," she became the first US Navy ship to fire on a German ship, three months before the United States officially entered World War II. The incident led President Franklin D. Roosevelt to issue what became known as his "shoot-on-sight" order, with the intention of creating a casus belli in the Atlantic, provoking Germany to declare war on the US.

The Continuation War, also known as the Second Soviet–Finnish War, was a conflict fought by Finland and Nazi Germany against the Soviet Union during World War II.

The Soviet Union and Finland had previously fought the Winter War from 1939 to 1940, which ended with the Soviet failure to conquer Finland and the Moscow Peace Treaty. Numerous reasons have been proposed for the Finnish decision to invade, with regaining territory lost during the Winter War regarded as the most common. Other justifications for the conflict include Finnish President Risto Ryti's vision of a Greater Finland and Commander-in-Chief Carl Gustaf Emil Mannerheim's desire to annex East Karelia.

The Vietnam War was an armed conflict in Vietnam, Laos, and Cambodia fought between North Vietnam and South Vietnam and their allies. North Vietnam was supported by the Soviet Union and China, while South Vietnam was supported by the United States and other anti-communist nations. The conflict was the second of the Indochina wars and a proxy war of the Cold War between the Soviet Union and US. The Vietnam War was one of the postcolonial wars of national liberation, a theater in the Cold War, and a civil war, with civil warfare a defining feature from the outset. Direct US military involvement escalated from 1965 until US forces were withdrawn in 1973. The fighting spilled into the Laotian and Cambodian civil wars, which ended with all three countries becoming communist in 1975.

Alaska Airlines Flight 1866 was a regularly scheduled passenger flight operated by Alaska Airlines from Anchorage, Alaska, to Seattle, Washington, with several intermediate stops in southeast Alaska. The aircraft was a Boeing 727-100 with U.S. registry N2969G manufactured in 1966. On September 4, 1971, the aircraft operating the flight crashed into a mountain in Haines Borough, about 18 miles west of Juneau, Alaska, while on approach for landing. All 111 people aboard were killed. The subsequent investigation found that erroneous navigation readouts led the crew to descend prematurely. No definitive cause for the misleading data was found. It was the first fatal jet aircraft crash involving Alaska Airlines, and remained the deadliest single-aircraft accident in United States history until June 24, 1975, when Eastern Air Lines Flight 66 crashed. It is still, however, the worst air disaster in Alaska state history.
