 Romans did explorations toward this area and probably reached, with Suetonius Paulinus, the area of Adrar.There is evidence (coins, fibulas) of Roman commerce in Akjoujt and Tamkartkart near Tichit.Berbers moved south to Mauritania beginning in the 3rd century, followed by Arabs in the 8th century, subjugating and assimilating Mauritania's original inhabitants.
