ロンドン条約
On 25 May 1946 the Transjordan became the "Hashemite Kingdom of Transjordan" when the ruling 'Amir' was re-designated as 'King' by the parliament of Transjordan on the day it ratified the Treaty of London. 25 May is still celebrated as independence day in Jordan although officially the mandate for Transjordan ended on 17 June 1946 when in accordance with the Treaty of London the ratifications were exchanged in Amman and Transjordan gained full independence.
