Fiji was a British Crown Colony from 1874 to 1970, and an independent Dominion in the Commonwealth from 1970 to 1987. During this period, the Head of State was the British Monarch, but in practice his or her functions were normally exercised locally by the Governor prior to independence (on 10 October 1970), and by the Governor-General prior to the proclamation of a republic on 7 October 1987.
Note that from 1877 to 3 July 1952, Governors of Fiji were also High Commissioners for the Western Pacific.
