Israeli–Palestinian conflict
1948 Arab–Israeli War

Following the Declaration of the Establishment of the State of Israel on 14 May 1948, the Arab League decided to intervene on behalf of Palestinian Arabs, marching their forces into former British Palestine, beginning the main phase of the 1948 Arab–Israeli War. The overall fighting, leading to around 15,000 casualties, resulted in cease-fire and armistice agreements of 1949, with Israel holding much of the former Mandate territory, Jordan occupying and later annexing the West Bank and Egypt taking over the Gaza Strip, where the All-Palestine Government was declared by the Arab League on 22 September 1948.
