Sultan Ahmad al-Mansur (1578-1603) was one of the most important rulers in the history of Morocco, which to this day bears the mark of his twenty-five year rule in the sixteenth century. Though famed for his cunning diplomacy in the power struggle over the Mediterranean, and his allegiance with Britain against Spain in the conquest for the newly discovered Americas, he was more than a political and military tactician. A descendent of the Prophet Muhammad himself, al-Mansur was a charismatic religious authority with ambitions to become Caliph and ruler of all Muslims. Spanning four continents, Dr. Garcia-Arenal places this fascinating figure in a context of political intrigue, discovery and military conquest. With insightful analysis, a glossary and a guide to further reading, this book is the ideal introduction to a multifaceted figure who fully deserves the epithet "Maker of the Muslim World".
