This episode explores how Britain’s global role evolved between 1951 and 1997, tracing the nation’s shift from imperial power to modern European state as it navigated decolonisation, the Cold War, the Suez Crisis, nuclear diplomacy, and the search for a new international identity. We examine Britain’s relationships with the United States and Europe, its attempts to maintain influence through the Commonwealth, its changing defence commitments, and the political debates surrounding EEC entry and membership. From post‑war retreat to Thatcher’s assertive foreign policy and Major’s efforts to redefine Britain’s place in a rapidly changing world, the episode reveals how successive governments grappled with the challenge of maintaining global relevance in the second half of the twentieth century.
