The British Parliament and Foreign Policy in the 20th Century explores the ways in which parliaments in Britain and internationally have affected and democratized foreign policy since World War I. This latest special issue by Parliamentary History includes six essays by expert historians on the positive and negative implications of increased parliamentary involvement in foreign policy. The essays discuss minority protection under the League of Nations, the atomic question in the aftermath of World War II, the Falklands War, parliamentary debates during the Iraq War, and relationships between the UK and European Parliaments. The contributors use these subjects as starting points to consider a broad range of topics and questions, such as increased participation by MPs, parliamentary procedure, extra-parliamentary networks, effects of constitutional changes, and the rise of transnationalisation. Using new data from recent analysis of parliamentary debates, archival sources, and media accounts, this is an insightful examination of the complex and evolving nature of parliamentary politics.
