This article analyzes Turkish foreign policy during the Iranian oil crisis of 1951–1953 and argues that Turkey shaped its policy based on Cold War politics. While Turkey cared less for Iran’s nationalization of oil, it was more concerned about the political implications of the crisis. At the beginning of the crisis, Turkey was focused on guaranteeing its own NATO membership. After joining NATO in 1952, the country assumed a more active role in the crisis. As the coalition behind Premier Dr Mohammad Mosaddegh dissolved, Turkey became more concerned about both the internal situation in Iran and the broader Middle Eastern context following the July 21, 1952 events in Iran and the 1952 Egyptian coup. The strongest opposition to Mosaddegh came from Ayatollah Abul Qassim Kashani who was both an important religious figure and the speaker of the Majlis. Turkey was concerned about Kashani’s politics of a “third bloc” and supported Mosaddegh’s pro-American position. Keeping Mosaddegh in power was in line with Turkey’s general Middle Eastern policy which aimed at forming a Western-oriented regional defense organization. This article will analyze the shaping of Turkish foreign policy towards the Iranian oil crisis within the context of this regional rivalry.
