The Victoria Falls Conference took place on 26 August 1975 aboard a South African Railways train halfway across the Victoria Falls Bridge on the border between the unrecognised state of Rhodesia (today Zimbabwe) and Zambia. It was the culmination of the "détente" policy introduced and championed by B. J. Vorster, the Prime Minister of South Africa, which was then under apartheid and was attempting to improve its relations with the Frontline States to Rhodesia's north, west and east by helping to produce a settlement in Rhodesia. The participants in the conference were a delegation led by the Rhodesian Prime Minister Ian Smith on behalf of his government, and a nationalist delegation attending under the banner of Abel Muzorewa's African National Council (UANC), which for this conference also incorporated delegates from the Zimbabwe African National Union (ZANU), the Zimbabwe African People's Union (ZAPU) and the Front for the Liberation of Zimbabwe (FROLIZI). Vorster and the Zambian President Kenneth Kaunda acted as mediators in the conference, which was held on the border in an attempt to provide a venue both sides would accept as neutral. The conference failed to produce a settlement, breaking up on the same day it began with each side blaming the other for its unsuccessful outcome. Smith believed the nationalists were being unreasonable by requesting preconditions for talks—which they had previously agreed not to do—and asking for diplomatic immunity for their leaders and fighters. The nationalists contended that Smith was being deliberately intransigent and that they did not believe he was sincere in seeking an agreement if he was so adamant about not giving diplomatic immunity. Direct talks between the government and the Zimbabwe African People's Union followed in December 1975, but these also failed to produce any significant progress. The Victoria Falls Conference, the détente initiative and the associated ceasefire, though unsuccessful, did affect the course of the Rhodesian Bush War, as they gave the nationalist guerrillas significant time to regroup and reorganise themselves following the decisive security force counter-campaign of 1973–74. A further conference would follow in the Geneva Conference in 1976 . Background After the Wind of Change of the early 1960s, the British government under Harold Wilson and the predominantly white minority government of the self-governing colony of Rhodesia, led by the Prime Minister Ian Smith, were unable to agree terms for the latter's full independence. Rhodesia unilaterally declared independence on 11 November 1965.
