From 1496, the Spanish conquered numerous possessions on the North African coast, which had been captured since 1496: Melilla (1496), Mers El Kébir (1505), Oran (1509), Bougie (1510), Tripoli (1510), Algiers, Shershell, Dellys, and Tenes. The Spaniards later led numerous unsuccessful expeditions to take Algiers in the Algiers expedition in 1516, another in 1518 and another failed expedition in 1541.
