Why was palestine created?

There are two definitions for Palestine, and the answer changes depending on what definition you are using. The first way is to refer to the British Mandate of Palestine which includes the Modern State of Israel (except for the Golan Heights), the Gaza Strip, and the West Bank. The second way is to refer to exclusively those territories which the Palestinian Authority claims will serve as a basis for a future Palestinian State (State of Palestine): the West Bank and Gaza Strip.

The British Mandate of Palestine was created by the British who took an interest in the territory because of its pivotal location along the Asia-Africa landbridge and because of its Biblical significance.

The State of Palestine was created in 1988 to respond to the need for the Palestinian refugees of the Arab-Israeli Wars to create a state for themselves to self-govern and try to end their statelessness.
