Descent-based slavery is a system where individuals inherit slave status from their ancestors and are forced to work for their masters for life. This practice is prevalent in West African countries like Niger, Mauritania, and Mali, where deeply ingrained cultural norms perpetuate the exploitation of vulnerable groups. Real-life stories illustrate the severe abuses faced by individuals, particularly young girls, under this system, as well as the efforts of various organizations working to combat and end this form of slavery.
