Early Cold War Espionage

1945–1965 CE

The end of the Second World War replaced the wartime alliance with a prolonged contest between the Western powers and the Soviet Union. Intelligence services concentrated on political subversion, military technology, nuclear secrets and the identification of agents operating under diplomatic, commercial or deep-cover identities. Defections and major penetrations of Western institutions made counter-espionage a defining concern in Britain, the United States and their allies.

During the 1950s and early 1960s espionage intersected with decolonisation, alliance politics and rapid advances in weapons and communications. Cases such as the Cambridge spy network and the Portland spy ring demonstrated the scale of Soviet intelligence activity, while Berlin remained a major operational frontier. This context supports fiction centred on British, American and Soviet intelligence rivalry before the later Cold War’s growing emphasis on terrorism and détente.
