In November 1965, livid over sanctions imposed by the United Nations and chagrined that their "kith and kin" in Britain appeared to share Wilson's hostility to the secessionist regime in Salisbury, Smith and his followers opted for a Unilateral Declaration of Independence (UDI). At the time of UDI, Rhodesian whites numbered approximately a quarter of a million souls constituting a mere 5 percent of the overall population. Rhodesian whites insisted that the Great Zimbabwe was the workmanship of the Phoenicians or Portuguese, any people other than the indigenous blacks. As far as the Olympics were concerned, the Rhodesian quandary manifested itself even before UDI. The National Olympic Committee of Rhodesia had been a constituent part of the National Olympic Committee of the Federation of Rhodesia and Nyasaland. Support for Rhodesia and Brundage emanated from some surprising quarters, among them the little known National Front of Liberation of Romania. Rhodesia's expulsion was patently unfair.
