The idea of establishing a Palestinian state in the West Bank and Gaza Strip has evolved through various proposals and disputes. During the British mandate period, numerous territorial and constitutional models were proposed for Palestine, none of them winning the agreement of all parties. In 1947, the United Nations Partition Plan for Palestine was voted for. The leaders of the Jewish Agency for Palestine accepted parts of the plan, while Arab leaders refused it. This triggered the 1947–1949 Palestine war and led, in 1948, to the establishment of the state of Israel on a part of Mandate Palestine as the Mandate came to an end.
The Gaza Strip came under Egyptian occupation, and the West Bank was ruled by Jordan, before both territories were occupied by Israel in the 1967 Six-Day War. Since then there have been proposals to establish a Palestinian state. In 1969, for example, the Palestine Liberation Organization (PLO) proposed the establishment of a binational state over the whole of the former British Mandate territory. This proposal was rejected by Israel, as it would have amounted to the disbanding of the state of Israel. The basis of the current proposals is for a two-state solution on either a portion of or the entirety of the Palestinian territories—the Gaza Strip and the West Bank, including East Jerusalem, which have been occupied by Israel since 1967.
