Nuclear rivalry, competing ideologies and proxy conflicts after 1945.
The Cold War was a global contest centred on the United States and Soviet Union after 1945. Nuclear weapons made direct great-power war extraordinarily dangerous, but conflict continued through alliances, espionage, propaganda, economic competition and wars fought by others.
The phrase can conceal local agency. Revolutions, decolonisation and regional rivalries were not simply controlled from Washington or Moscow, even when superpower support transformed them.
Disputes over Germany and eastern Europe hardened wartime mistrust. The Truman Doctrine, Marshall Plan, communist consolidation and creation of NATO and the Warsaw Pact produced rival blocs.
Korea, Cuba, Vietnam and Afghanistan showed different forms of escalation. Deterrence reduced some risks while creating permanent preparation for catastrophe.
Détente produced agreements without ending competition. Economic weakness, political opposition and Gorbachev's reforms destabilised the Soviet bloc. The revolutions of 1989 and Soviet dissolution in 1991 ended the European order but not all conflicts it had shaped.
The Cold War was bipolar at the level of superpower rivalry but multipolar in practice. Governments and movements in Asia, Africa, Latin America and the Middle East pursued their own aims rather than acting only as proxies.
Newly opened archives transformed interpretations after 1991, but access remains unequal. Oral history and local archives help recover experiences obscured by Washington- and Moscow-centred narratives.
