Interregnum (Transjordan) in the context of "San Remo conference"

Establishment of the Emirate of Transjordan refers to the government that was set up in Transjordan on 11 April 1921, following a brief interregnum period.

Abdullah, the second son of Sharif Hussein (leader of the 1916 Great Arab Revolt against the Ottoman Empire), arrived from Hejaz by train in Ma'an in southern Transjordan on 21 November 1920. His stated aim was fighting the French in Syria, after they had defeated the short-lived Arab Kingdom of Syria during the Battle of Maysalun on 24 July 1920.

The Emirate of Transjordan (Arabic: إمارة شرق الأردن, romanized: Imārat Sharq al-Urdun, lit. 'the emirate east of the Jordan'), officially the Amirate of Trans-Jordan, was a British protectorate established on 11 April 1921, which remained as such until achieving formal independence as the Kingdom of Transjordan in 1946.

After the Ottoman defeat in World War I, the Transjordan region was administered within OETA East; after the British withdrawal in 1919, this region gained de facto recognition as part of the Hashemite-ruled Arab Kingdom of Syria, administering an area broadly comprising the areas of the modern countries of Syria and Jordan. Transjordan became a no man's land following the July 1920 Battle of Maysalun, during which period the British in neighbouring Mandatory Palestine chose to avoid "any definite connection between it and Palestine". Abdullah entered the region in November 1920, moving to Amman on 2 March 1921; later in the month a conference was held with the British during 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.
