While the origin of the village remains disputed, the establishment of the Serer in the area is assumed to have begun when the advance of the Almoravids in the 11th century forced them to leave the Sénégal River valley, occupying the Petite Côte and the region of the Sine River. Another theory claims that Joal and Fadiouth have been founded by the Guelowar when they were expelled from the kingdom of Kaabu. Both of these theories find their validation by observing the frequency of certain surnames, indicating ethnic group in the region.

In the early 17th century, until around 1635, a community of Portuguese Jewish traders lived in the village, trading with West Africa, Portugal and the Netherlands. Protected by the local chief, they were allowed to openly profess their religion, to the annoyance of the Portuguese (Catholic) government.

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.

It was during that time that the passage of El Hadj Umar Tall was commemorated by building a mosque for his appraisal. The important architectural legacy recalling this memorable passing is in danger of deterioration.
