a semi-autonomous Palestinian region in the Middle East on the W bank of the River Jordan, comprising the hills of Judaea and Samaria and part of Jerusalem: formerly part of Palestine (the entity created by the League of Nations in 1922 and operating until 1948): became part of Jordan after the ceasefire of 1949: occupied by Israel since the 1967 Arab-Israeli War. In 1993 a peace treaty between Israel and the Palestine Liberation Organization provided for the West Bank to become a self-governing Palestinian area;a new Palestinian National Authority assumed control of parts of the territory in 1994–95, but subsequent talks broke down and Israel reoccupied much of this in 2001–02 and continues to maintain most existing Israeli settlements.
