 The Mandara society developed into a socially stratified system, with Sultan and royalty, farmers, horse breeders, artisans, iron workers and smiths forming a distinct endogamous occupation-inheriting castes.The caste system among the Mandara people integrated the concept that the strata have innate pollution and therefore they are stigmatized, however there is no evidence that their Islamic belief integrated the differences between the socially differentiated castes in their society to have been divinely sanctioned.The Mandara people also featured an endogamous slave strata.
