Independence day is the National Holiday of Jordan and is celebrated annually on 25 May.
Known as 'Eid al-Istiklaal', the holiday marks the independence of Jordan on 25 May 1946 when British control ended and Jordan was declared a Kingdom
After the end of World War I, the emirate of Transjordan was officially formed from the British Mandate of Palestine in 1922 and was officially recognised by the Council of the League of Nations in 1922. As-Sayyid Abdullah bin al-Husayn was nominated as Emir, but many aspects of the rule of the country remained under British control.
Following World War 2, the British pushed for an end to their mandate in the region and on 25 May 1946, the United Nations approved the end to the British Mandate and Jordan became an independent sovereign state officially known as the Hashemite Kingdom of Transjordan.
The Transjordanian Parliament declared as-Sayyid Abdullah bin al-Husayn as King Abdullah I, the first monarch of the Hashemite Empire.
After capturing parts of Jerusalem and the West Bank during the 1948 Arab–Israeli War, King Abdullah I took the title King of Jordan. The name of the state was changed to The Hashemite Kingdom of Jordan on 1 December 1948.
