Prague Spring in the context of Slovak Socialist Republic

Czechoslovakia (/ˌtʃɛkoʊsloʊˈvæki.ə, ˈtʃɛkə-, -slə-, -ˈvɑː-/ CHEK-oh-sloh-VAK-ee-ə, CHEK-ə-, -⁠slə-, -⁠VAH-; Czech and Slovak: Československo, Česko-Slovensko) was a landlocked country in Central Europe created in 1918 when it declared its independence from Austria-Hungary. In 1938, after the Munich Agreement, the Sudetenland became part of Nazi Germany. Between 1939 and 1945, the state ceased to exist, as Slovakia proclaimed its independence and Carpathian Ruthenia became part of Hungary, while the German Protectorate of Bohemia and Moravia was proclaimed in the remainder of the Czech Lands. In 1939, after the outbreak of World War II, former Czechoslovak president Edvard Beneš formed a government-in-exile and sought recognition from the Allies.

After World War II, Czechoslovakia was re-established under its pre-1938 borders, with the exception of Carpathian Ruthenia, which became part of the Ukrainian SSR (a republic of the Soviet Union). The Communist Party seized power in a coup in 1948. From 1948 to 1989, Czechoslovakia was part of the Eastern Bloc with a planned economy. Its economic status was formalized in membership of Comecon from 1949 and its defense status in the Warsaw Pact of 1955. A period of political liberalization in 1968, the Prague Spring, ended when the Soviet Union, assisted by other Warsaw Pact countries, invaded Czechoslovakia. In 1989, as Marxist–Leninist governments and communism were ending all over Central and Eastern Europe, Czechoslovaks peacefully deposed their communist government during the Velvet Revolution, which began on 17 November 1989 and ended 11 days later on 28 November when all of the top Communist leaders and Communist party itself resigned. On 31 December 1992, Czechoslovakia split peacefully into the two sovereign states of the Czech Republic and Slovakia.

On 20–21 August 1968, the Czechoslovak Socialist Republic was jointly invaded by four Warsaw Pact countries: the Soviet Union, the Polish People's Republic, the People's Republic of Bulgaria, and the Hungarian People's Republic. The invasion stopped Alexander Dubček's Prague Spring liberalisation reforms and strengthened the authoritarian wing of the Communist Party of Czechoslovakia (KSČ).

About 250,000 Warsaw Pact troops (rising afterwards to about 500,000), supported by thousands of tanks and hundreds of aircraft, participated in the overnight operation, which was code-named Operation Danube. The Socialist Republic of Romania and the People's Republic of Albania refused to participate. East German forces, except for a small number of specialists, were ordered by Moscow not to cross the Czechoslovak border just hours before the invasion, because of fears of greater resistance if German troops were involved, due to public perception of the previous German occupation three decades earlier. 137 Czechoslovaks were killed and 500 seriously wounded during the occupation.

A series of major student, intellectual and other protests against the ruling Polish United Workers' Party of the Polish People's Republic took place in Poland in March 1968. The crisis led to the suppression of student strikes by security forces in all major academic centres across the country and the subsequent repression of the Polish dissident movement. It was also accompanied by mass emigration following an antisemitic (branded "anti-Zionist") campaign waged by the minister of internal affairs, General Mieczysław Moczar, with the approval of First Secretary Władysław Gomułka of the Polish United Workers' Party (PZPR). The protests overlapped with the events of the Prague Spring in neighboring Czechoslovakia – raising new hopes of democratic reforms among the intelligentsia. The Czechoslovak unrest culminated in the Warsaw Pact invasion of Czechoslovakia on 20 August 1968.

The anti-Zionist campaign began in 1967, and was carried out in conjunction with the USSR's withdrawal of all diplomatic relations with Israel after the Six-Day War, but also involved a power struggle within the PZPR itself. The subsequent purges within the ruling party, led by Moczar and his faction, failed to topple Gomułka's government but resulted in an exile from Poland of thousands of communist individuals of Jewish ancestry, including professionals, party officials and secret police functionaries appointed by Joseph Stalin following the Second World War. In carefully staged public displays of support, factory workers across Poland were assembled to publicly denounce Zionism. At least 13,000 Poles of Jewish origin emigrated in 1968–1972 as a result of being fired from their positions and various other forms of harassment.

Václav Havel (Czech: [ˈvaːt͡slav ˈɦavɛl] ; 5 October 1936 – 18 December 2011) was a Czech statesman, author, poet, playwright, and dissident. Havel served as the last president of Czechoslovakia from 1989 until 1992, prior to the dissolution of Czechoslovakia on 31 December, before he became the first president of the Czech Republic from 1993 to 2003. He was the first democratically elected president of either country after the fall of communism. As a writer of Czech literature, he is known for his plays, essays and memoirs.

His educational opportunities having been limited by his bourgeois background under the Czechoslovak Socialist Republic, Havel first rose to prominence as a playwright. In works such as The Garden Party and The Memorandum, Havel used an absurdist style to criticize the Communist system. After participating in the Prague Spring and being blacklisted after the Warsaw Pact invasion of Czechoslovakia, he became more politically active and helped found several dissident initiatives, including Charter 77 and the Committee for the Defense of the Unjustly Prosecuted. His political activities brought him under the surveillance of the StB secret police, and he spent several periods as a political prisoner, the longest of his imprisoned terms being nearly four years, between 1979 and 1983.

Eurocommunism was a trend in the 1970s and 1980s within various Western European communist parties, which said they had developed a theory and practice of social transformation more relevant for Western Europe. During the Cold War, they sought to reject the influence of the Soviet Union and its Communist Party. The trend was especially prominent in Italy, Spain, and France. It is commonly considered to have been prompted by the Prague Spring. Although the various parties converged against the Soviet factor, their own doctrines remained as different at the dissolution of the movement as they originally were before 1968.

Campus protest or student protest is a form of student activism that takes the form of protest at university campuses. Such protests encompass a wide range of activities that indicate student dissatisfaction with a given political or academics issue and mobilization to communicate this dissatisfaction to the authorities (university or civil or both) and society in general and hopefully remedy the problem. Protest forms include but are not limited to: sit-ins, occupations of university offices or buildings, strikes etc. More extreme forms include suicide such as the case of Jan Palach's, and Jan Zajíc's protests against the end of the Prague Spring and Kostas Georgakis' protest against the Greek junta of 1967–1974.

The Armed Forces of the Republic of Poland (Polish: Siły Zbrojne Rzeczypospolitej Polskiej, pronounced [ˈɕiwɨ ˈzbrɔjnɛ ʐɛt͡ʂpɔsˈpɔlitɛj ˈpɔlskʲɛj]; abbreviated SZ RP), also called the Polish Armed Forces and popularly called Wojsko Polskie in Poland ([ˈvɔj.skɔ ˈpɔl.skjɛ], roughly "the Polish Military"—abbreviated WP), are the national armed forces of the Republic of Poland. The name has been used since the early 1800s, but can also be applied to earlier periods.

The Polish Legions and the Blue Army, composed of Polish volunteers from the United States and those who switched sides from the Central Powers, were formed during World War I. In the war's aftermath, the Polish Army was reformed from the remnants of the partitioning powers' forces and expanded significantly during the Polish–Soviet War of 1920. World War II dramatically impacted Polish military structures, with the initial defeat by Nazi Germany and the Soviet Union invasions leading to the dispersion of Polish forces into the underground. After the war, the Polish People's Army (LWP) was formed, and its standards aligned with those of the former Warsaw Pact. The LWP's reputation suffered due to its role in political suppression both domestically and abroad, such as during the Prague Spring. Following the fall of communism, Poland shifted towards Western military standards, joining NATO in 1999, participating in missions in Iraq and Afghanistan, and undertaking substantial modernization of its forces.

Alexander Dubček (Slovak pronunciation: [ˈaleksander ˈduptʂek]; 27 November 1921 – 7 November 1992) was a Czechoslovak and later Slovak statesman who served as the First Secretary of the Presidium of the Central Committee of the Communist Party of Czechoslovakia (KSČ) (de facto leader of Czechoslovakia) from January 1968 to April 1969 and as Chairman of the Federal Assembly from 1989 to 1992 following the Velvet Revolution. He oversaw significant reforms to the communist system during a period that became known as the Prague Spring, but his reforms were reversed and he was eventually sidelined following the Warsaw Pact invasion in August 1968.

Best known by the slogan, "Socialism with a human face", Dubček led a process that accelerated cultural and economic liberalization in Czechoslovakia. Reforms were opposed by conservatives inside the party who benefited from the Stalinist economy, as well as interests in the neighbouring Soviet-bloc who feared contagion, western subversion, strategic vulnerability, and loss of institutional power. For reasons of institutional interests in the Soviet Union such as those of the military and KGB, false reports, and the growing concern among the Soviet leadership that Dubček was no longer able to maintain control of the country, Czechoslovakia was invaded by half a million Soviet-led Warsaw Pact troops on the night of 20–21 August 1968. This was intended to enable a coup by conservative forces. That coup, however, could not materialize due to lack of a viable pro-Soviet replacement leadership and the unexpected extraordinary popularity of Dubček and the reformist leadership. Soviet intervention ushered in a period of maneuver between conservatives and reformers where conservatives relied on Soviet influence to shift the balance of power, reversing reforms of the Prague Spring.

Madeleine Jana Korbel Albright (born Marie Jana Körbelová, later Korbelová; May 15, 1937 – March 23, 2022) was an American diplomat and political scientist who served as the 64th United States secretary of state under President Bill Clinton from 1997 to 2001. A member of the Democratic Party, she was the first woman to hold the position.

Born in Prague, Czechoslovakia, Albright immigrated to the United States after the 1948 communist coup d'état when she was eleven years old. Her father, diplomat Josef Korbel, settled the family in Denver, Colorado, and she became a U.S. citizen in 1957. Albright graduated from Wellesley College in 1959 and earned a PhD from Columbia University in 1975, writing her thesis on the Prague Spring. She worked as an aide to Senator Edmund Muskie from 1976 to 1978, before serving as a staff member on the National Security Council under Zbigniew Brzezinski. She served in that position until 1981 when President Jimmy Carter left office.
