This book takes us on a journey through one of the most exciting phases in Islamic history: the Umayyad state. From the moment of its founding by Muawiyah ibn Abi Sufyan, amidst an atmosphere of great strife, chapters of conflict and politics begin, recounting the tragedy of Hussein. Then, the banner of opposition is raised with the Zubayrid movement, in a scene where ambitions and principles intermingle. We move to the heart of power, where severity is practiced as a method, and its features are evident in politics and society, before setting out with the armies of conquest to the ends of the earth, from Khurasan in the east to Andalusia in the west. Between the sword and the pen, another face of the state emerges: that of justice and reform, and the beginnings of administrative organization, followed by a remarkable urban boom encompassing cities, mosques, and palaces. In the background, the features of Umayyad society take shape, with its diverse cultures and tribal systems, while literature flourishes, and poems of pride, satire, and wisdom are written. Then, in the final chapter of the conflict, the inevitable end arrives, with the state falling at the Battle of the Zab, and the page of the Umayyads is turned. This book offers a fascinating analytical account based on solid historical sources, reshaping our understanding of one of the most vibrant and exciting periods in Arab and Islamic history.
