Rabin was chief of staff of the Israeli army 1964–68, commanding the Israeli Defence Forces in the Six-Day War of June 1967 against Israel’s Arab neighbours. As leader of the Labour Party, he was Prime Minister from 1974 until 1977. He regained leadership of the party and the premiership in 1992, and in the following year signed a peace accord with Yasser Arafat of the Palestine Liberation Organization. This agreement brought Rabin the Nobel Peace Prize in 1994 (jointly with Arafat and Israeli Foreign Minister Shimon Peres). Arab and Jewish ultra-nationalists remained opposed to the settlement; while attending a peace rally in Tel Aviv in 1995, Rabin was assassinated by a Jewish right-wing extremist.
