The Gambia achieved independence on 18 February 1965, as a constitutional monarchy within the Commonwealth, with Elizabeth II as Queen of the Gambia, represented by the Governor-General. Shortly thereafter, the national government held a referendum proposing that the country become a republic. This referendum failed to receive the two-thirds majority required to amend the constitution, but the results won widespread attention abroad as testimony to the Gambia's observance of secret balloting, honest elections, civil rights, and liberties.
On 24 April 1970, the Gambia became a republic within the Commonwealth, following a second referendum. Prime Minister Sir Dawda Kairaba Jawara assumed the office of President, an executive post, combining the offices of head of state and head of government.
