Despite the Almoravid domination of Spain in the 11th and 12th centuries, there seems to be little evidence of contact during that time between Mauritania and Europe. The inhospitable coastline of Mauritania continued to deter voyagers until the Portuguese began their African explorations in the 15th century. The area of Mauritania was of little interest to either Arab or European conquerors; the existence of gold reserves in the interior was not yet known, and the important trade routes passed the territory well to the east, through Timbuktu. The Saadi dynasty conquered much of the Saharan interior but did not show interest in expanding their territory westward.
