Transnational Activism and Domestic Politics: Arms Exports and the Anti-Apartheid Struggle in the UK–South Africa Relations (1959–1994)

In 1964, the UK government imposed an arms embargo on South Africa, which it maintained until the end of the white minority rule. What explains this embargo? Using mainly archival evidence, this paper demonstrates that domestic political dynamics in the United Kingdom mediated the influence of the transnational anti-apartheid and anti-colonial struggles on the British government. The United Kingdom imposed and maintained this embargo due in part to a domestic advocacy network, whose hub was the Anti-Apartheid Movement. The paper provides a comprehensive explanation of an important issue in British foreign policy, the anti-colonial struggle, and Southern Africa's history. There are theoretical implications for foreign policy analysis concerning the role of advocacy networks, interactions between local and global activism, the role of political parties’ ideology and contestation, the effects on foreign policy of changes in a normative environment, the effects of norm contestation, and normative determinants of sanctions.
