The Mamluks are Mozenrath's undead underlings from the Aladdin TV series.
They are the only other inhabitants of Mozenrath's kingdom the Land of the Black Sand: a desolated and hostile land that was once ruled by an evil sorcerer Destane, who adopted Mozenrath. At some point, likely when he felt that Destane had nothing left to teach him, he killed him and turned him into one of his undead mamluks, before taking over his throne. The Mamluk soldiers have secure control over the Land of the Black Sand, but they are not powerful enough to conquer the other kingdoms that Mozenrath wants to rule.
