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.
