In a country where surveys of the religious composition estimated the Buddhist majority to be between 70% and 90%,[99][100][101][102][103][104][105] Diệm's policies generated claims of religious bias. Diem was widely regarded by historians as having pursued pro-Catholic policies that antagonized many Buddhists. Specifically, the government was regarded as being biased towards Catholics in public service and military promotions, as well as the allocation of land, business favors, and tax concessions.[106] Diệm also once told a high-ranking officer, forgetting that he was a Buddhist, "Put your Catholic officers in sensitive places. They can be trusted." Many officers in the Army of the Republic of Vietnam converted to Catholicism in the belief that their military prospects depended on it.[107] The distribution of weapons to village self-defense militias intended to repel Việt Cộng guerrillas saw weapons only given to Catholics. Some Buddhist villages converted en masse to Catholicism in order to receive aid or to avoid being forcibly resettled by Diệm's regime,[108] with Buddhists in the army being denied promotion if they refused to convert to Catholicism.[109] Some Catholic priests ran their own private armies,[110] and in some areas forced conversions, looting, shelling, and demolition of pagodas occurred.[111]
