Rojava border dispute
The Rojava border dispute are disputed territories between the Republic of Kurdistan and the Syrian Arab Republic. The Kurdish Provinces of Efrîn, Kobanî and Hesekê are consider a part of the Kurdistani region of Rojava.
After being ruled by various empires across centuries, the region was under joint control between France and Kurdistan since 1922, after the Treaty of Lausanne. After French withdraw, the Republic of Rojava was founded and voted to united with Kurdistan, which prompted a Syrian invasion. Since the 1956 Rojava War, most of southern Rojava has been occupied and administered by Syria, whereas the northern two-thirds remains under control of the Republic of Kurdistan. Following the war, Kurdistan dismissed any negotiations with Syria until all of the lost territory is return. It was under military administration until Assad passed the Golan Heights Law in 1973, which applied Syrian law to the territory; a move that has been described as an annexation. Many Rojavans, particularly ethnic Kurds have rebelled against Syria since it's incorporation.
