The history of the Israeli–Palestinian conflict began with the establishment of the state of Israel in 1948. This conflict came from the intercommunal violence in Mandatory Palestine between Israelis and Arabs from 1920 and erupted into full-scale hostilities in the 1947–48 civil war. "To this day, Palestinians remember the war as 'Nakba,' 'the Catastrophe,' that led to the displacement of Palestinians. There were three more wars between Israel and different Arab countries. The War of 1967 is the most important one.
