British rule of Colonial Nigeria ended in 1960, when the Nigeria Independence Act 1960[2] made the federation an independent sovereign state.

Elizabeth II remained head of state as the Queen of Nigeria, as well as other dominions and commonwealth realms.

Three people held the office of governor-general during the whole existence of the Federation of Nigeria: Sir Abubakar Tafawa Balewa held office as prime minister (and head of government).

The Federal Republic of Nigeria came into existence on 1 October 1963.

Following the abolition of the monarchy, former Governor-General Nnamdi Azikiwe became President of Nigeria, as a ceremonial post under the 1963 constitution.
