Claim: 1948 Palestinian exodus (also known as the Nakba) had over 800,000 refugees from 29 Nov. 1947 to 20 July 1949.
Evidence: The 1948 Palestinian exodus, also known as the Nakba (Arabic: النكبة‎, al-Nakbah, literally "disaster", "catastrophe", or "cataclysm"), occurred when more than 700,000 Palestinian Arabs – about half of prewar Palestine's Arab population – fled or were expelled from their homes, during the 1948 Palestine war. The term nakba also refers to the period of war itself and events affecting Palestinians from December 1947 to January 1949.
