This book focuses on the Man?uriyya regiment, the mamluks of sultan al-Man?ur Qalawun. It traces the lives of these mamluks during the career of their master Qalawun (ca. 1260-1290), the period they ruled the Sultanate of Egypt and Syria de jure or de facto (1290-1310), and their aftermath, during the third reign of sultan al-Na?ir Mu?ammad b. Qalawun (1310-1341). Based on dozens of contemporary Arabic sources, the book traces the political and military events of the turbulent Man?uriyya period, as well as the basic military-political principles and socio-political practices that evolved during this period. It suggests that the Man?uriyya period marks the beginning of the demilitarization, or politicization, of the Mamluk sultanate.
