The Damascus Sanjak (Turkish: Şam Sancağı; Arabic: سنجق دمشق) was a prefecture (sanjak) of the Ottoman Empire, occupying the center of Ottoman Syria, located in modern-day Syria and Lebanon. The city of Damascus was the Sanjak's capital.[1] It was bordered by the Hauran Sanjak to the south, Hama Sanjak to the north, and Beirut Vilayet to the west.
When dividing Ottoman Syria, the French mandate authorities detached the westernmost part of the sanjak and allocated it to its newly created Greater Lebanon, while the rest remained in the shriveled Syrian state.
