  Dhar Tichitt and Oualata were prominent among the early urban centres, dated to 2000 BC, in present-day Mauritania. About 500 stone settlements littered the region in the former savannah of the Sahara. Its inhabitants fished and grew millet. It has been found that the Soninke of the Mandé peoples were responsible for constructing such settlements. Around 300 BC, the region became more desiccated and the settlements began to decline, most likely relocating to Koumbi Saleh. From the type of architecture and pottery, it is believed that Tichit was related to the subsequent Ghana Empire. Old Jenne (Djenne) began to be settled around 300 BC, producing iron and with sizeable population, evidenced in crowded cemeteries. The inhabitants and creators of these settlements during these periods are thought to have been ancestors of the Soninke people.
