During the 1948 Arab-Israeli War, Transjordan’s Arab Legion attempted to capture the entire city of Jerusalem, shelling it and cutting off its Jewish residents from the coastal plain. Western portions of Jerusalem came under Israel’s control only after Israeli forces broke the Arab siege of the city. In the first four weeks of Arab attacks, 200 Jewish civilians were killed and over 1,000 were wounded in Jerusalem. But, defending themselves, Israeli forces managed to capture some suburbs and villages from the Arabs.

The Israeli defenders were not as successful in protecting the Jewish community of eastern Jerusalem. On May 28, 1948, the Jewish Quarter of the Old City fell to the Arab Legion. After 10 months of fighting, an armistice agreement was signed on April 3, 1949, dividing Jerusalem along the November 1948 ceasefire lines of Israeli and Transjordanian forces, with several areas of no-man’s land. The armistice line served as a temporary border between what had formerly been two mixed communities. Western Jerusalem became Israel’s capital city, while eastern Jerusalem, including the holy sites, was occupied by Transjordan, which in 1949 became the Hashemite Kingdom of Jordan. The city was essentially divided between two armed camps separated by barbed wire, concrete walls, minefields and bunkers.
