The flag of Jordan, officially adopted on 16 April 1928, is based on the 1916 flag of the Arab Revolt against the Ottoman Empire during World War I. The flag consists of horizontal black, white, and green bands that are connected by a red chevron. The colours are the Pan-Arab Colors, respectively representing the Abbasid, Umayyad, and Fatimid or Rashidun caliphates. The red chevron is for the Hashemite dynasty, and the Arab Revolt.

The Emirate of Transjordan, officially known as the Amirate of Trans-Jordan, was a British protectorate established on 11 April 1921, which remained as such until achieving formal independence in 1946.
Herbert Samuel's proclamation in Salt, August 1920, for which he was admonished by Curzon
12 March 1921 British memorandum explaining the situation of Transjordan: "His Majesty's Government have been entrusted with the Mandate for 'Palestine'. If they wish to assert their claim to Trans-Jordan and to avoid raising with other Powers the legal status of that area, they can only do so by proceeding upon the assumption that Trans-Jordan forms part of the area covered by the Palestine Mandate. In default of this assumption Trans-Jordan would be left, under article 132 of the Treaty of Sèvres, to the disposal of the principal Allied Powers."
25 March 1921 proposal, approved a week later, to include Transjordan via Article 25: "On the assumption that ... provision is made in some way in final political arrangements as regards Trans-Jordania for its inclusion within the boundaries of Palestine as eventually fixed, but under a form of administration different from that of Palestine, however undesirable it may be for His Majesty's Government themselves to propose alterations of the mandates at this stage, they were inclined to view that when the "A" mandates come to be considered by the Council of the League it would be wise in this case to propose to that body the insertion...after article 24 of the Palestine mandate..."
The first general election in Transjordan took place on 2 April 1929
