The Tichitt Culture, or Tichitt Tradition, was created by proto-Mande peoples, namely the ancestors of the Soninke people. In 4000 BCE, the start of sophisticated social structure developed among herders amid the Pastoral Period of the Sahara. Saharan pastoral culture was intricate. By 1800 BCE, Saharan pastoral culture expanded throughout the Saharan and Sahelian regions. The initial stages of sophisticated social structure among Saharan herders served as the segue for the development of sophisticated hierarchies found in African settlements, such as Dhar Tichitt. After migrating from the Central Sahara, proto-Mande peoples established their civilization in the Tichitt region of the Western Sahara. The Tichitt Tradition of eastern Mauritania dates from 2200 BCE to 200 BCE.
