Palestinian Fedayeen insurgency refers to the armed cross-border conflict, which peaked between 1949 and 1956, involving Israel and Palestinian militants, mainly based in the Gaza Strip, under the nominal control, of the All-Palestine Protectorate – a Palestinian client-state of Egypt declared in October 1948, which became the focal point of the Palestinian fedayeen activity. The conflict was parallel to the Palestinian infiltration phenomenon. Hundreds were killed on the course of the conflict, which declined after the 1956 Suez War.
