The Israeli name for the Arab–Israeli war called by the Arabs the October War. The war began on 6 October, the Feast of Yom Kippur, Israel’s most important holy day, when Egyptian forces crossed the Suez Canal and breached the Israeli Bar Lev Line. Syrian troops threw back Israeli forces on the Golan Heights, occupied by the latter since the Six-Day War. The war lasted three weeks, in which time Israel pushed Syrian forces back into Syria and crossed the Canal, encircling an Egyptian army. In the aftermath, disengagement agreements were signed by Israel with Syria in 1974 and with Egypt in 1974 and 1975. The Israeli withdrawal from Sinai was completed in 1982 after the 1978 Israeli–Egyptian peace treaty.
