The chapter focuses on the geopolitics of Northern Cyprus, a de facto state or a contested state. We analyze Northern Cyprus not only as an object but also as a subject of great power rivalry in the Eastern Mediterranean. While it has long been shaped by external competition—during the Cold War and beyond—this rivalry has recently further evolved through Turkey’s shifting regional role. There have been increasing tensions in the region due to hydrocarbon resources and energy transit routes. Northern Cyprus, however, has had limited agency in its relations with the Republic of Cyprus, the European Union, the UK, the US, Israel, and other powers. As a de facto state, it remains heavily dependent on Turkey and subject to its influence in most affairs. We argue that this dependence is unlikely to diminish in the near future, yet it does not erase the persistent aspirations and efforts of Turkish Cypriots to assert their own agency.
