Zengi: The Architect of Jihad and the Counter-Crusade

On Christmas Eve 1144, the walls of Edessa collapsed in fire and the medieval world changed forever. A Muslim army had recaptured a Crusader capital for the first time since the First Crusade, sending shockwaves from the Euphrates to Rome and launching the catastrophic Second Crusade. The man responsible was Imad al-Din Zengi, warlord, oath-breaker, political genius, and the most consequential figure in the history of the medieval Counter-Crusade.

This book tells the full story of Zengi's extraordinary career: from the execution of his father and his flight as a ten-year-old to the city of Mosul, through three decades of military apprenticeship and political calculation, to the construction of the trans-regional Zengid state that transformed the fractured Islamic world of the twelfth-century Levant into a unified military power capable of reversing the Crusader advance.

Drawing on Islamic, Latin, Armenian, and Syriac sources, and engaging seriously with the critical scholarship of Carole Hillenbrand and others, this book argues that Zengi deserves recognition not as the pious champion of jihad that medieval court literature celebrated, but as something rarer and more interesting: the architect of a historical transformation he never lived to complete, built by methods he would never apologise for, in service of goals he never quite admitted were his own.
