The Arab-Israeli conflict originated with the creation and ratification of the nation of Israel, in the Palestinian region, in 1948.
Step-by-step explanation:
Although conflict between Israelis and Arabs has been as ancient as their peoples, true trouble arose in earnest in the 1920´s and it found its peak after the civil war of 1947-1948, when the State of Israel was formed and recognized by the majority of the nations of the world, against the opposition of Palestine and the Arab nations.
