The 1948 Arab–Israeli War was the second and final stage of the 1947–1949 Palestine war. It formally began following the end of the British Mandate for Palestine at midnight on 14 May 1948; the Israeli Declaration of Independence had been issued earlier that day, and a military coalition of Arab states entered the territory of British Palestine in the morning of 15 May.
The first deaths of the 1947–1949 Palestine war occurred on 30 November 1947 during an ambush of two buses carrying Jews. There had been tension and conflict between the Arabs and the Jews, and between each of them and the British forces since the 1917 Balfour Declaration and the 1920 creation of the British Mandate of Palestine. British policies dissatisfied both Arabs and Jews. Arab opposition developed into the 1936–1939 Arab revolt in Palestine, while the Jewish resistance developed into the 1944–1947 Jewish insurgency in Palestine.
