Slavery in Mauritania
Slavery has been called "deeply rooted" in the structure of the northwest African country of Mauritania and estimated to be "closely tied" to the ethnic composition of the country, although it has also been estimated that "Widespread slavery was traditional among ethnic groups of the largely nonpastoralist south, where it had no racial origins or overtones; masters and slaves alike were black", despite the cessation of slavery across other African countries and an official ban on the practice since 1905. The French colonial administration declared an end to slavery in Mauritania in 1905, but did little to enforce that ban.
