Wolof people
The Wolof people are a West African Muslim ethnic group found in northwestern Senegal, The Gambia, and southwestern coastal Mauritania. In Senegal, the Wolof are the largest ethnic group (~ 39%), and their combined population exceeds 6 million. The Wolof people, like other West African ethnic groups, have historically maintained a rigid, endogamous social stratification that included nobility, clerics, castes and slaves. The Wolof caste system has existed at least since the 15th-century.
