In June 1961, Kuwait became independent with the end of the British protectorate and the Sheikh Abdullah Al-Salim Al-Sabah became Emir of Kuwait. Kuwait's national day, however, is celebrated on 25 February, the anniversary of the coronation of Sheikh Abdullah (it was originally celebrated on 19 June, the date of independence, but concerns over the summer heat caused the government to move it). Under the terms of the newly drafted Constitution, Kuwait held its first parliamentary elections in 1963. Kuwait was the first of the Arab states of the Persian Gulf to establish a constitution and parliament.
