Mauritania Banned Slavery in 1981. It Didn't Become a Crime There Until 2007.

Mauritania holds a distinction no country wants: it was the last nation in the world to formally abolish slavery, doing so by presidential decree in 1981. That date alone understates how limited the abolition actually was in practice. The 1981 decree ended slavery’s legal status but created no criminal penalty for anyone who continued holding people in bondage, meaning slaveholding carried no legal consequence at all until Mauritania passed a dedicated anti-slavery law in 2007, 26 years later, that finally made the practice a prosecutable crime, punishable by five to ten years in prison.

The population most affected by this gap between legal abolition and actual criminalization is the Haratine, an ethnic group descended from West Africans historically enslaved by Mauritania’s Arab-Berber Moor population, who today make up an estimated 30 to 40 percent of the country’s total population. The term “Haratine” itself carries contested and layered meaning within Mauritanian society, referring variously to formerly enslaved people, their descendants regardless of current legal status, or a broader social category tied to both ancestry and ongoing economic and political marginalization, distinctions that researchers studying the term note complicate any simple headcount of how many Haratine remain in conditions of actual bondage today.

Despite the 2007 law, rights organizations including Minority Rights Group and Anti-Slavery International have continued documenting slavery’s persistence in Mauritania well into the 21st century, estimating tens of thousands of people, some assessments running as high as 90,000, still living in conditions that meet international definitions of slavery, generally in rural, agricultural, or domestic servitude settings where legal enforcement rarely reaches. Prosecutions under the 2007 law have remained rare relative to the scale of the documented problem, and rights groups have repeatedly criticized Mauritanian courts and law enforcement for treating slavery cases as private civil disputes over labor or family matters rather than as the criminal offenses the 2007 law formally defines them as.

Mauritanian civil society organizations advocating against slavery, including groups founded and led by Haratine activists themselves, have faced their own legal and political obstacles, with some anti-slavery organizers facing arrest or prosecution for their activism even as the government maintains that slavery has been legally eliminated. The persistent gap between Mauritania’s formal legal position, that slavery ended in 1981 and has been criminal since 2007, and the documented reality that forms of hereditary bondage continue affecting tens of thousands of people, remains one of the most extensively documented cases anywhere in the world of a legal abolition failing to translate into an actual end to the practice it outlawed.
