Arab–Israeli conflict
There was sectarian conflict within the British Mandate territory between Palestinian Jews and Arabs commencing in the 1920s, escalating into a full-scale Palestinian civil war in 1947. Taking the side of the Palestinian Arabs, especially following the Israeli Declaration of Independence, the neighbouring Arab countries invaded the by-then former Mandate territory in May 1948, commencing the First Arab–Israeli War. Large-scale hostilities mostly ended with ceasefire agreements after the 1973 Yom Kippur War. Peace agreements were signed between Israel and Egypt in 1979, resulting in Israeli withdrawal from the Sinai Peninsula and the abolition of the military governance system in the West Bank and Gaza Strip, in favor of Israeli Civil Administration and consequent unilateral annexation of the Golan Heights and East Jerusalem.
