The territories of what would become the states of Israel and Lebanon were once part of the Ottoman Empire which lasted from 1299 until its defeat in World War I and subsequent dissolution in 1922. As a result of the Sinai and Palestine Campaign in 1917, the British occupied Palestine and parts of what would become Syria. French troops took Damascus in 1918. The League of Nations officially gave the French the Mandate of Syria and the British the Mandate of Palestine after the 1920 San Remo conference, in accordance with the 1916 Sykes–Picot Agreement.
