The UAE National Day is celebrated yearly on 2 December to commemorate the formation of the United Arab Emirates. The seventh emirate, Ras Al Khaimah, was added to the federation on 10 February 1972 making it the last emirate to join.
Prior to the formation of the UAE, the emirates were part of the Trucial States, a British protectorate established through truce treaties in 1820, 1853 and 1896. In 1968, the British government under the Prime Minister Harold Wilson declared its intention to withdraw its forces east of the Suez, which included its forces in the Trucial States. The British, and Americans according to leaked diplomatic cables, encouraged some type of union between the emirates, which were seen as weak and surrounded by regional powers in Iran and Saudi Arabia, both of whom have territorial disputes with some of the emirates. The proposed union was at one point set to include Qatar and Bahrain, but those efforts were abandoned with Bahrain declaring independence August 1971, and Qatar in September 1971. Days prior to the expiration of British treaties on 1 December, the Iranian army supported by the Iranian naval forces occupied the islands of Abu Musa and the Lesser and Greater Tunbs. The UAE declared independence the day after the expiry of the treaties on 2 December, albeit without the emirate of Ras Al Khaimah, which had sided with Saudi Arabia in some of its disputes with the other emirates, and had grievances with the union for establishing relations with Iran despite its occupation of Abu Musa and the Lesser and Greater Tunbs. However, Ras Al Khaimah later joined the union on 10 February 1972. Sheikh Zayed bin Sultan Al Nahyan, was the federation’s first president and is regarded as the country’s founding father. Recently, the UAE National Day holiday with the Emirati Martyrs’ Day on November 30.
