Lancaster House Agreement: An independence agreement for Rhodesia is signed in London by Lord Carrington, Sir Ian Gilmour, Robert Mugabe, Joshua Nkomo, Bishop Abel Muzorewa and S.C. Mundawarara.

The Lancaster House Agreement is an agreement signed on 21 December 1979 in Lancaster House, following the conclusion of a constitutional conference where different parties discussed the future of Zimbabwe Rhodesia, formerly known as Rhodesia. The agreement effectively concluded the Rhodesian Bush War. It also marked the nullification of Rhodesia's Unilateral Declaration of Independence, as British colonial authority was to be restored for a transition period, during which free elections under supervision by the British government would take place. Crucially, ZANU and ZAPU, the political wings of ZANLA and ZIPRA, would be permitted to stand candidates in the forthcoming elections. This was however conditional to compliance with the ceasefire and the verified absence of voter intimidation.

Rhodesia, officially the Republic of Rhodesia from 1970, was an unrecognised state in Southern Africa that existed from 1965 to 1979. Rhodesia served as the de facto successor state to the British colony of Southern Rhodesia following a unilateral declaration of independence issued by the ruling white-minority government. Throughout this fourteen-year period, Rhodesia faced internal conflict and political unrest. Following the Lancaster House Agreement in 1979, the territory returned to British political control and then subsequently gained internationally recognised independence as Zimbabwe in 1980.

Peter Alexander Rupert Carington, 6th Baron Carrington, Baron Carington of Upton, was a British Conservative Party politician and hereditary peer who served as Defence Secretary from 1970 to 1974, Foreign Secretary from 1979 to 1982, chairman of the General Electric Company from 1983 to 1984, and Secretary General of NATO from 1984 to 1988. In Margaret Thatcher's first government, he played a major role in negotiating the Lancaster House Agreement that ended the conflict in Rhodesia and enabled the creation of Zimbabwe. Carington later served as the Chairman of the Steering Committee for the Bilderberg Group's meetings from 1990 to 1998.
