Direct British rule of the Uganda Protectorate ended in 1962 with the Uganda Independence Act, which granted independence of the protectorate under the name "Uganda" but retained the British monarch, Elizabeth II, as nominal head of state and Queen of Uganda. Her constitutional roles as head of state were mostly delegated to the Governor-General of UgandaSir Walter Coutts, who was the only holder of the office.
In 1963, Uganda adopted a new constitution which abolished the links with the British monarchy. Uganda became a republic within the Commonwealth. However, the new Ugandan state was deliberately referred to as a state rather than a republic, and the constituent native kingdoms (such as Buganda) continued in existence. The description "State" implied that the country was not a republic but instead a federation of tribal kingdoms. Following the proclamation of the State of Uganda on 9 October 1963, the Kabaka (King) of Buganda, Edward Mutesa II, became the first President of Uganda. Uganda did not become a republic de jure until 1966 with Obote's conflict with President Edward Mutesa II.
