This book focuses on the Man??riyya regiment, the mamluks of sultan al-Man??r Qal?w?n. It traces the lives of these mamluks during the career of their master Qal?w?n (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-N??ir Mu?ammad b. Qal?w?n (1310–1341). Based on dozens of contemporary Arabic sources, the book traces the political and military events of the turbulent Man??riyya period, as well as the basic military-political principles and socio-political practices that evolved during this period. It suggests that the Man??riyya period marks the beginning of the demilitarization, or politicization, of the Mamluk sultanate.
