Mandatory Palestine
Updated: Wikipedia source
Mandatory Palestine, officially known as Palestine, was a British administrative territory between 1920 and 1948 in the region of Palestine. From 1922, under the terms of the League of Nations, it was a mandated territory, administered by the British under the Mandate for Palestine. After the Arab Revolt against the Ottoman Empire during the First World War in 1916, British forces drove Ottoman forces out of the Levant. For the British, the United Kingdom had agreed in the McMahon–Hussein Correspondence that it would honour Arab independence in case of a revolt but, in the end, the United Kingdom and France divided what had been Ottoman Syria under the Sykes–Picot Agreement—an act of betrayal in the eyes of the Arabs. Another issue that later arose was the Balfour Declaration of 1917, in which Britain promised its support for the establishment of a Jewish "national home" in Palestine. Mandatory Palestine was then established in 1920, and the British obtained a Mandate for Palestine from the League of Nations in 1922. Mandatory Palestine was designated as a Class A Mandate, based on its social, political, and economic development. This classification was reserved for post-war mandates with the highest capacity for self-governance. All Class A mandates other than Mandatory Palestine had gained independence by 1946. During the Mandate, the area saw successive waves of Jewish immigration and the rise of nationalist movements in both the Jewish and Arab communities. Competing interests of the two populations led to the 1936–1939 Arab revolt in Palestine and the 1944–1948 Jewish insurgency in Mandatory Palestine. The United Nations Partition Plan for Palestine to divide the territory into two states, one Arab and one Jewish, was passed in November 1947. The 1948 Palestine war ended with the territory of Mandatory Palestine divided among the State of Israel, the Hashemite Kingdom of Transjordan, which annexed territory on the West Bank of the Jordan River, and the Kingdom of Egypt, which established the "All-Palestine Protectorate" in the Gaza Strip.
