يوسف بن تاشفين
Yusuf ibn Tashfin had in the meantime brought the large area of what is now known as Morocco, Western Sahara, and Mauritania into complete subjection. In 1062 he founded the city of Marrakech. In 1080, he conquered the kingdom of Tlemcen (in modern-day Algeria) and founded the present city of that name, his rule extending as far east as Oran.
