Maurice Bishop held de facto government control for most of the People's Revolutionary Government period (from 13 March 1979 until 14 October 1983). On 14 October 1983 Bishop was deposed by Bernard Coard and Bishop was killed on 19 October. Coard held power only briefly before military government was declared. After the invasion of Grenada by the United States, the pre-revolutionary system of government and the office of Prime Minister were restored on 4 December 1984. The Grenadian government acknowledges Bishop as a former prime minister, but not Coard nor any other individual who held de facto or de jure power in this period.[35]
Rhodesia (1965–1970)
Ian Smith was Prime Minister of Rhodesia following a unilateral declaration of independence on 11 November 1965. Although Rhodesia considered Elizabeth II to be Queen of Rhodesia,[36] this title was not accepted by her. Acting in his vice-regal capacity and under direction from the UK government, the Governor of Southern Rhodesia, Humphrey Gibbs, dismissed the prime minister and his government but this action was ignored by Smith. The state remained unrecognised by the United Kingdom and the wider international community. Following a referendum, Rhodesia declared itself a republic on 2 March 1970. Smith remained in office throughout this period.
