The Treaty of London was signed between the United Kingdom and the Emirate of Trans-Jordan on 22 March 1946 and came into force on 17 June 1946.

However, the United Kingdom controlled financial matters and most foreign policy issues.

Transjordan's impending independence was recognised on 18 April 1946 by the League of Nations during the last meeting of that organisation.

When King Abdullah applied for membership in the newly formed United Nations, his request was vetoed by the Soviet Union, citing that the nation was not "fully independent" of British control.

Despite this, Jordan only became a full member of the United Nations on 14 December 1955 as part of a wider compromise in which 16 countries joined on the same day.
