Prior to this, in November 1947, the United Nations General Assembly endorsed a plan for the partition of the then British Mandate of Palestine, providing for the creation of an Arab State and a Jewish State, with Jerusalem to be placed in Trusteeship with international status. The plan was not accepted by the Palestinian Arabs and Arab States and only partially accepted by the Jewish Agency of Palestine. On 14 May 1948, the United Kingdom relinquished its mandate over Palestine and the State of Israel was proclaimed. The following day, the Arab States invaded.
