サアド朝
From the 11th to the 19th centuries, Western Sahara was one of the links between the Sub-Saharan and North African regions. During the 11th century, the Sanhaja tribal confederation allied with the Lamtuna tribe to found the Almoravid dynasty. The conquests of the Almoravids extended over present-day Morocco, Western Algeria, and the Iberian peninsula to the north and Mauritania and Mali to the south, reaching the Ghana Empire. By the 16th century, the Arab Saadi dynasty conquered the Songhai Empire based on the Niger River. Some Trans-Saharan trade routes also traversed Western Sahara.
