Spanning the greater part of the thirteenth century, the career of the Mamluk sultan of Egypt and Syria, al-Mansur Qalawun, is of great interest for the light it sheds on the major themes of early Mamluk history: the emergence of a new political and administrative structure, characterized by increased militarization and mamlukization; the role of the caliphate and the nature of sultani authority; the problem of succession; Mamluk factionalism; Egyptian-Syrian relations; relations with Mongols and Crusaders; and the importance, not to mention the strategic and complex nature, of international trade in the Mamluk realm. Not only does this work fill a gap in knowledge of the early Mamluk period, complementing the studies we have of Baybars's and al-Nasir Muhammad's reigns, but it goes further than most in analyzing the institutions of the period, and uses hitherto neglected materials to illuminate theoretical and practical questions of Mamluk rule.
