The Ottoman Empire had swallowed up King Solomon's land of Israel and held onto it till the end of World War I. It then was given to the British and French to take care of until they knew what would happen to it.
On April 24, 1920, the British wrote the mandate for Palestine, to become the Jewish National Home. It contained 120,466 square km.
However, on July 24, 1922, it was reduced in order to create Transjordan because they had neglected to take into consideration that an Arab complained, wanting his own kingdom. Britain reduced the National Home by 77%. We accepted the piece left, anyway. The pre 1967 Israel amounted to 20,770 square km or, 8,019 square miles. The width is only 12 miles.
