Post-war central and eastern Europe (1945–2000)

Security (buffer zone against western invasion), ideology (spreading Marxism-Leninism), and resources (exploiting eastern Europe's industry and food to rebuild the USSR).

Salami tactics = gradually removing coalition partners one by one until only communists remained in power. The phrase was coined by Hungarian communist Mátyás Rákosi.

Founded January 1949. It coordinated eastern bloc economies under Soviet direction — assigning each state an economic role and creating dependency on Moscow. It was also the Soviet response to the US Marshall Plan.

Signed May 1955, in direct response to West Germany joining NATO. It gave the USSR the legal right to station troops in member states and later justified military intervention in Hungary (1956) and Czechoslovakia (1968).

Yugoslavia was the only eastern bloc state to break free of Soviet control early. In 1948 Stalin expelled Yugoslavia from the Cominform and imposed an economic blockade, but Tito refused to back down. Yugoslavia survived, proving independence from Moscow was possible.

Triggered by raised work quotas and low living standards. Soviet tanks suppressed the uprising within two days; 50–100 killed, thousands arrested. East German leader Ulbricht survived in power.

Poland's Gomułka promised to keep Poland inside the Warsaw Pact — Moscow's red line. Hungary's Nagy announced withdrawal from the Warsaw Pact, which Moscow could not tolerate. The extent of the challenge, not just its existence, determined the response.

Reform movement under Czechoslovak leader Alexander Dubček — 'socialism with a human face' — including press freedom and travel rights. Ended by a Warsaw Pact invasion of 500,000 troops on 20–21 August 1968. Dubček was removed from power.

The Soviet claim (after 1968) that the USSR had the right to intervene militarily in any socialist country where socialism was threatened. It remained policy until Gorbachev renounced it in 1988.

Staged public trials in which prominent communists confessed to fabricated crimes, used to eliminate rivals and create fear. Examples: László Rajk (Hungary, 1949) and Rudolf Slánský (Czechoslovakia, 1952).

Nagy was arrested after Soviet tanks crushed the uprising, secretly tried for treason, and executed in June 1958. About 2,500 Hungarians were killed and 200,000 fled as refugees.

The USA and NATO did not intervene militarily in any of the uprisings — not East Germany (1953), Hungary (1956), or Czechoslovakia (1968). Without external support, opposition movements had no counterweight to Soviet military force. Western passivity was confirmed by Eisenhower's refusal to act during the Hungarian Revolution despite Radio Free Europe's encouragement.

Gorbachev's informal policy (named by his spokesperson after Frank Sinatra's 'My Way') that each eastern European state could choose its own path. It replaced the Brezhnev Doctrine and removed the Soviet military guarantee that had held communist regimes in power since 1956.

Poland → Hungary → East Germany → Czechoslovakia → Romania: the order in which communist regimes fell in 1989. Each collapse accelerated the next through the 'contagion' or domino effect.

Romania was the only violent transition. Protesters in Timisoara and Bucharest were fired on by Securitate forces. The army switched sides. Nicolae Ceausescu and his wife Elena were arrested, tried in a summary military court, and executed on 25 December 1989.

Serbian nationalist leader who became President of Serbia in 1989. He used media control and ethnic nationalist rhetoric to build power, supported Serb paramilitaries in Croatia and Bosnia aiming for a 'Greater Serbia', and launched military operations in Kosovo. He was indicted by the ICTY in 1999 and died in The Hague in 2006 before his trial concluded.

In July 1995, Bosnian Serb forces under Ratko Mladic killed approximately 8,000 Bosniak Muslim men and boys from the UN 'safe area' of Srebrenica. The ICJ later ruled it constituted genocide — the worst atrocity in Europe since 1945.

A peace agreement ending the Bosnian War, brokered by the USA. Bosnia-Herzegovina was divided into two entities: the Serb Republic and the Muslim-Croat Federation. Milosevic signed on behalf of the Bosnian Serbs, attempting to reposition himself as a peacemaker.

Poland's 'shock therapy' economic reform launched January 1990, designed by Finance Minister Leszek Balcerowicz. Prices were freed, subsidies cut, currency made convertible. Immediate effects: GDP fell ~11.6% in 1990, inflation reached 585%, unemployment rose from near-zero to 16% by 1993. Poland then recovered fastest in the region, surpassing 1989 GDP levels by around 1996.

Poland's shock therapy caused severe short-term pain but produced the fastest long-term recovery in the region and a stable macroeconomic base. Gradual approaches (e.g. Romania, Bulgaria) avoided the sharpest immediate drops but resulted in prolonged stagnation. However, Poland also had stronger civil society (Solidarity) which arguably made shock therapy socially survivable.

Voter frustration with the economic hardship of shock therapy and the fragmented, quarrelsome post-Solidarity governments. Kwasniewski had reinvented himself as a moderate social democrat. His victory demonstrated democratic consolidation (power changed hands peacefully) rather than a reversal of transition.

The Church had been a key pillar of resistance under communism. After 1989 it pressed for anti-abortion legislation (passed 1993) and religious education in schools, creating significant social and political controversy. The Church's social conservatism created tensions with liberal democratic norms, adding a culture-war dimension to Polish politics.

Germany reunified (October 1990); Warsaw Pact disbanded (July 1991); Soviet Union dissolved (December 1991); free elections across central/eastern Europe; 'shock therapy' economies caused short-term hardship; resurgent nationalism led to Yugoslav wars; Poland, Hungary, Czech Republic joined NATO in 1999; EU enlargement followed in 2004.

That Gorbachev was a necessary but not sufficient cause. Long-term economic failure removed legitimacy; organised civil resistance (Solidarity, Charter 77) provided alternative structures; Gorbachev removed the military guarantee as an immediate trigger; contagion amplified the process. All four were needed — no single cause alone explains the collapse.
