In orthodox Serer religion and custom, interfaith and interracial marriages are forbidden. Banishment and disinheritance may be levied against a Serer who fails to follow these customary teachings. The Serer-Noon (a sub-group of the Serer people) strongly adhere to these teachings. It was for this reason that the first Senegalese president Léopold Sédar Senghor did not receive support from the Serer community, especially the ultra—traditional Serer. Although born to an aristocratic Serer family, he did not receive support from the Serer community due to his marriage to his French wife (see below). Instead, he was supported by other ethnic groups such as the Wolof and Fula. In return, Senghor failed to develop Serer villages and towns.
