teaching the course "Negro History and Culture" in the fall of 1937. It was the first time this course was offered within the City Colleges of New York. During the Rapp-Coudert hearings, informers reported that his class was "liberal and progressive." Yergan was denied re-appointment and dismissed for his politics. The Cold War led him to become disillusioned with Communism and ultimately to become strongly hostile to Communism. In 1948, Yergan was ousted as the director of Council on African Affairs following disputes with other members, causing his turn to the right. In 1952, he spoke against Communism on a visit to South Africa at the Bantu Men's Social Center in Johannesburg, claiming the main anti-apartheid group, the African National Congress was controlled by the South African Communist Party. In 1955, Yergan again visited South Africa where he praised apartheid and denied that South African blacks were suffering from apartheid. The same year, he also visited the Portuguese colony of Angola, where he praised Portuguese rule as "just and efficient". In 1961, Yergan became president of the American Committee for Aid to Katanga Freedom Fighters (ACAKFF), a conservative group that lobbied the United States to recognise Katanga. Yergan was recruited by a conservative activist Marvin Liebman who founded the ACAKFF and wanted a black man as its president to offset charges of racism as Katanga was known to be a sham. Yergan claimed that the Congolese government had been taken over by Communists and praised the Katangan men for wanting to "defend themselves, their wives, their children and places of work". Despite his claims, most of the soldiers fighting for Katanga were not Katangans, but rather white mercenaries from Europe, South Africa, Southern Rhodesia and the United States. The mercenaries were known to the Congolese as "les affreux" ("the frightful ones") on account of their brutality to blacks. In 1962, Yergan wrote a letter to the Secretary of State, Dean Rusk, expressing his fury that the United States had denied Moïse Tshombe a visa to visit the United States while the Kennedy administration had "ceremoniously welcomed...Nikita Khrushchev, Fidel Castro, the late Patrice Lumumba, and Holden Roberto". In 1964, Yergan praised aspects of the South African governments "separate development" plan. In 1966, he became co-chairman together with William Rusher of the conservative American-African Affairs Association, which lobbied the United States to recognize the white minority government of Rhodesia.
