Rhodesia's Unilateral Declaration of Independence (UDI) was a statement adopted by the Cabinet of Rhodesia on 11 November 1965, announcing that Rhodesia (previously Southern Rhodesia)[n 1] a British territory in southern Africa that had governed itself since 1923, now regarded itself as an independent sovereign state. 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 in 1776. 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 (until 1974) Portugal.
The Rhodesian government, which mostly comprised members of the country's white minority of about 5%, was indignant when, amid the UK colonial government's Wind of Change policies of decolonisation, 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 of self-government, and that the British government was betraying them by withholding it.
A stalemate developed between the British and Rhodesian prime ministers, Harold Wilson and Ian Smith respectively, between 1964 and 1965. The dispute largely surrounded the British condition that the terms for independence had to be acceptable "to the people of the country as a whole"; Smith contended that this was met, while the UK and African Nationalist Rhodesian leaders held that it was not. After Wilson proposed in late October 1965 that the UK might safeguard future black representation in the Rhodesian parliament by withdrawing some of the colonial government's devolved powers, then presented terms for an investigatory Royal Commission that the Rhodesians found unacceptable, Smith and his Cabinet declared independence. Calling this treasonous, the British colonial governor, Sir Humphrey Gibbs, formally dismissed Smith and his government, but they ignored him and appointed an "Officer Administering the Government" to take his place.
While no country recognised the UDI, the Rhodesian High Court deemed the post-UDI government legal and de jure in 1968. The Smith administration initially professed continued loyalty to Queen Elizabeth II, but abandoned this in 1970 when it declared a republic in an unsuccessful attempt to win foreign recognition. The Rhodesian Bush War, a guerrilla conflict between the government and two rival communist-backed black Rhodesian groups, began in earnest two years later, and after several attempts to end the war Smith concluded the Internal Settlement with non-militant nationalists in 1978. Under these terms the country was reconstituted under black rule as Zimbabwe Rhodesia in June 1979, but this new order was rejected by the guerrillas and the international community. The Bush War continued until Zimbabwe Rhodesia revoked its UDI as part of the Lancaster House Agreement in December 1979. Following a brief period of direct British rule, the country was granted internationally recognised independence under the name Zimbabwe in 1980.
