A former Minister of Health who had earned a reputation as a humanitarian while serving as an administrator in a U.S.-funded anti-yaws campaign, François Duvalier (known as ""Papa Doc"") soon established another dictatorship. His regime is regarded as one of the most repressive and corrupt of modern times, combining violence against political opponents with exploitation of Vodou to instill fear in the majority of the population. Duvalier's paramilitary police, officially the Volunteers for National Security (Volontaires de la Sécurité Nationale – VSN) but more commonly known as the Tonton Macoutes, named for a Vodou monster, carried out political murders, beatings, and intimidation. An estimated 30,000 Haitians were killed by his government. Duvalier employed rape as a political tool to silence political opposition. Incorporating many "houngans" into the ranks of the Macoutes, his public recognition of Vodou and its practitioners and his private adherence to Vodou ritual, combined with his reputed private knowledge of magic and sorcery, enhanced his popular persona among the common people and served as a peculiar form of legitimization.
