What support Ahidjo did enjoy among the Bamileke largely came from his pro-business policies. When the president resigned in 1982, his replacement, Paul Biya, sent his representative, Moussa Yaya, to reassure the West's businessmen that he would not prove unfriendly to their interests. Yaya mistrusted Biya, however, and only exacerbated Bamileke reservations. The Bamum, as well, were reluctant to see Cameroon's presidency change from a Muslim to a Christian. Much Bamileke and Bamum resentment for the Biya administration dates to this period.
