Russia and Europe 1900–17
Tsarist foreign policy before 1917
Before the Revolution, Tsarist Russia was drawn into the European alliance system. The Franco-Russian Alliance (1894) and the Anglo-Russian Entente (1907) completed the Triple Entente with France and Britain, aligning Russia against Germany and Austria-Hungary in the run-up to the First World War.

Revolutionary Russia 1917–33
Revolution and western hostility
The October Revolution (1917) and the Treaty of Brest-Litovsk (1918) took Russia out of the war and alarmed the West.
Western powers backed the Whites in the Civil War, and the new state founded the Comintern (1919) to promote world revolution.
Isolated, the USSR sought openings — notably the Treaty of Rapallo (1922) with Germany — and won diplomatic recognition (from Britain in 1924).

From collective security to the Grand Alliance
Facing Nazi Germany, the USSR joined the League of Nations (1934) and pursued 'collective security'.
When that failed, Stalin signed the Nazi-Soviet Pact (23 August 1939).
Germany's invasion (Operation Barbarossa, June 1941) drove the USSR into the Grand Alliance with Britain and the USA, sealed at Yalta and Potsdam (1945).

The Cold War hardens
Wartime allies split into hostile blocs. The USA's Truman Doctrine and Marshall Plan (1947) aimed to contain communism.
The Berlin Blockade (1948–49) and the founding of NATO (1949) deepened the divide; the USSR answered with the Warsaw Pact (1955).
After Stalin's death (1953), the Hungarian Uprising (1956) was crushed, showing the limits of any thaw.

Co-operation and coexistence 1956–79
Confrontation and détente
Khrushchev spoke of 'peaceful coexistence', yet crises followed: the Berlin Wall (1961) and the Cuban Missile Crisis (1962), the Cold War's closest brush with nuclear war.
The 1970s brought détente: arms control through SALT I (1972) and the Helsinki Accords (1975).

Aggression, decline and collapse 1979–91
The end of the Soviet system
Détente broke down with the Soviet invasion of Afghanistan (1979). Under Mikhail Gorbachev (from 1985), the reforms of glasnost ('openness') and perestroika ('restructuring') loosened control. The Berlin Wall fell in 1989, and the USSR was dissolved in 1991, ending the ideological clash that had shaped the century.
