After the destructive decades following the fall of the Safavid Empire, the Qajar dynasty inherited a weakened state and the growing threat of European imperial powers, culminating in two wars with Russia. In this book, Maziar Behrooz provides a history of the Qajar dynasty's navigation of this difficult period, beginning with the reign of Aqa Muhammad Shah and ending with that of Fath Ali Shah. Examining the key decisions taken by Qajar, Russian, British and other actors, the book argues that a reevaluation of the early-Qajar period is required, one which acknowledges the failures of its rulers, while recognising the external constraints they were under, and their successes in reuniting a formerly fragmented state in the face of overwhelming technological, economic and military firepower.
