In the aftermath of the 1947–49 war, the territory previously administered by the British Empire as Mandatory Palestine was de facto divided into three parts: the State of Israel, the Jordanian-held West Bank, and the Egyptian-held Gaza Strip. Of the estimated 950,000 Arabs that lived in the territory that became Israel before the war, over 80% fled or were expelled. The other 20%, some 156,000, remained. Arab citizens of Israel today are largely composed of the people who remained and their descendants. Others include some from the Gaza Strip and the West Bank who procured Israeli citizenship under family-unification provisions made significantly more stringent in the aftermath of the Second Intifada.
