Abstract

This article seeks to explore the evolution of Turkish-Iranian relations from the end of First World War to the end of Kaçar dynasty. It deals with main issues in this period such as tribes on the frontier, Iranian demands in the Paris Peace Conference and Lozan Conference, diplomatic relations between Tahran and Ankara, the rise of Rıza Han and Turkish policy, the 'Republican movement' in Iran and its consequences for bilateral relations, the Mosul question and Iran. It argues that there were two main di- mensions in the relations between Iran and Turkey in this period, regardless of leaders, regimes or ideologies: rivalry and colloboration.
