His Highness Sheikh Zayed bin Sultan Al Nahyan served as President of the United Arab Emirates since the formation of the Federation on 2 December 1971 and as Ruler of the Emirate of Abu Dhabi since 1966.
Sheikh Zayed’s enthusiasm for the Federation was a key factor in the formation of the UAE, he won support for the way in which he sought consensus and agreement among his fellow rulers. Sheikh Zayed was elected by these rulers to serve as the first President of the UAE, a post to which he was successively re-elected at five-year intervals.
