After the 1947-48 war, the new state of Israel was created in 78 percent of what had been British Mandate Palestine under the League of Nations since 1922. The 22 percent that was left was made up of the Gaza Strip, a small piece of land along the Mediterranean coast abutting the Egyptian border, the West Bank, along the Jordan River, and Arab East Jerusalem. From the end of the British Mandate in 1948 until the June War of 1967, the Gaza Strip was controlled by Egypt, the West Bank and East Jerusalem governed by Jordan.
In the 1967 War, Israel took over the West Bank, Gaza and East Jerusalem, the last 22 percent of historic Palestine. Those areas are now identified as the occupied territories.
