During the colonial period, Joal became one of the largest trading posts in Western Senegal. The setting up of European posts during the triangular trade made the village one of the regions that was penetrated by missionaries as early as the 17th-century. The proselytisation however was met by strong resistance by the local population, delaying large-scale evangelising by the Europeans to the 19th-century when Senegal became a French colony. In 1850, a mission was finally established in the village, the first priest was ordained there in 1885.
