Jordan, officially the Hashemite Kingdom of Jordan is an Arab kingdom in Western Asia, on the East Bank of the River Jordan. The country borders Saudi Arabia to the east and south-east, Iraq to the north-east, Syria to the north and the West Bank and Israel to the west, sharing control of the Dead Sea with the latter. Jordan's only port is at its south-western tip, at the Gulf of Aqaba, which is shared with Israel, Egypt, and Saudi Arabia. Over half of Jordan is covered by the Arabian Desert. However, the western part of Jordan is arable land and forests. Jordan is part of the Fertile Crescent. The capital city is Amman. According to the CIA World Factbook, Jordan has the second highest life expectancy in the Middle East, after Israel. The average life expectancy is one position behind the United Kingdom, although the age remains exactly the same (80.05 years). The precursor to modern Jordan was founded in 1921 as the Hashemite Emirate, and it was recognized by the League of Nations as a state under the British Mandate for Palestine in 1922 known as The Emirate of Transjordan. In 1946, Jordan became an independent sovereign state officially known as the Hashemite Kingdom of Transjordan. After capturing the West Bank area of Cisjordan during the1948–49 war with Israel, Abdullah I took the title King of Jordan and Palestine, and he officially changed the country's name to the Hashemite Kingdom of Jordan in April 1949.
