Jordan was not a member of the United Nations when the vote on the United Nations Partition Plan for Palestine was taken in November 1947, but following the establishment of the state of Israel on 14 May 1948, Jordan, then known as Transjordan, was one of the Arab League countries that invaded the former Palestinian Mandate territory precipitating the 1948 Arab–Israeli War. By war’s end, Jordan was in control of the West Bank and East Jerusalem (including the Old City). It expelled its Jewish population, and formally annexed the territories in 1950. After the Fedayeen attacks from Jordan decreased after Israel's victory in the 1956 Suez War, the tense relations between Israel and Jordan following the 1948 war eased.
