Arab–Israeli conflict
The modern conflict started with the 1948 Arab-Israeli war in parallel with the creation of state of Israel by the Jews. Later, on the course of the 1948 War, the All-Palestine Government was created in Gaza Strip by the Arab League, as an Arab Palestinian state.  Israel won the 1948 war, and the All-Palestine Government moved to Cairo in Egypt and were not allowed to return to Gaza.  They gradually lost importance, until abolished in 1959 by the Egyptian President Nasser.
