Israeli Military Governorate was a Military government body, established following the Six Day War in June 1967, in order to govern the civilian population of the West Bank, the Gaza Strip, the Sinai Peninsula and the Golan Heights. The governance was based on the Fourth Geneva Convention, which provides guidelines for military rule in occupied areas. East Jerusalem was the only exception from this order, and it was effectively added to Jerusalem municipal area as early as 1967, and extending Israeli law to the area (effectively annexing it).
