The culmination of a protracted dispute between the British and Rhodesian governments regarding the terms under which the latter could become fully independent, it was the first unilateral break from the United Kingdom by one of its colonies since the United States Declaration of Independence nearly two centuries before . The UK, the Commonwealth and the United Nations all deemed Rhodesia's UDI illegal, and economic sanctions, the first in the UN's history, were imposed on the breakaway colony . Amid near - complete international isolation, Rhodesia continued as an unrecognised state with the assistance of South Africa and Portugal . </P> <P> The Rhodesian government, which mostly comprised members of the country's white minority of about 5%, was indignant when, amid decolonisation and the Wind of Change, less developed African colonies to the north without comparable experience of self - rule quickly advanced to independence during the early 1960s while Rhodesia was refused sovereignty under the newly ascendant principle of "no independence before majority rule" ("NIBMAR"). Most white Rhodesians felt that they were due independence following four decades' self - government, and that the British government was betraying them by withholding it . This combined with the colonial government's acute reluctance to hand over power to black nationalists--the manifestation of racial tensions, Cold War anti-communism and the fear that a dystopian Congo - style situation might result--to create the impression that if the UK did not grant independence, Rhodesia might be justified in taking it unilaterally . </P>
