The Haratin , also spelled Haratine or Harratin, are an ethnic group found in western Sahel and southwestern Maghreb. The Haratin are mostly found in modern Mauritania (where they form a plurality), Morocco, Western Sahara, and Algeria. In Tunisia and Libya, they are referred to as Shwashin.
The Haratin speak Maghrebi Arabic dialects as well as various Berber languages. They have traditionally been characterised as the descendants of former Sub-Saharan slaves
The Haratin form an ethnic group distinct from Arab and Tuareg populations, as well as from the contemporary ethnic groups of sub-Saharan Africa. In Mauritania, however, where there are nearly 1.5 million Haratin, they have developed a separate sense of ethnic identity.
During the Roman occupation of Mauretania, the Godala Berber tribe fled to the south towards the Draa oasis and enslaved the local Haratin population. They have historically inherited their slave status and family occupation, have been endogamous, and socially segregated. Some communities differentiated two types of slaves, one called 'Abid or "slave" and Haratin or "freed slave". However, per anthropologist John Shoup, both 'Abid and Haratin were not free to own land or had equivalent property rights. Regardless of whether they were technically free or not, they were treated as socially inferior in the communities they lived in. Being denied the right and the ability to own any land, they historically survived by accepting a patron-client serf relationship either as domestic servant or as share-cropping labor (khammasin).
They became a common target of mandatory conscription by the Moroccan ruler Ismail Ibn Sharif as he sought to build a military that had no social or cultural attachment to any other Arab or Berber group in Maghreb. He conscripted the majority of able-bodied male Haratin and 'Abid that were present in Morocco at the time. This army was then commonly coerced into a series of wars in order to consolidate Ibn Sharif's power
