The Emirate of Transjordan (Arabic: إمارة شرق الأردن Imārat Sharq al-Urdun), also hyphenated as Trans-Jordan and previously known as Transjordania or Trans-Jordania, was a British protectorate established in April 1921. There were many urban settlements beyond the Jordan River, one in Al-Salt city and at that time the largest urban settlement east of the Jordan River. There was also a small Circassian community in Amman.
Transjordan had been a no man's land following the July 1920 Battle of Maysalun, and the British in neighbouring Mandatory Palestine chose to avoid "any definite connection between it and Palestine" until a March 1921 conference at which it was agreed that Abdullah bin Hussein would administer the territory under the auspices of the British Mandate for Palestine with a fully autonomous governing system.
The Hashemite dynasty ruled the protectorate, as well as the neighbouring Mandatory Iraq. On 25 May 1946, the Emirate became the "Hashemite Kingdom of Transjordan", achieving full independence on 17 June 1946 when in accordance with the Treaty of London ratifications were exchanged in Amman. In 1949 the country's official name was changed to the "Hashemite Kingdom of Jordan". |
