The book emphasizes dynastic legitimacy, the methods rulers use to cement authority, such as constructing genealogies and strategic marriages. It also investigates succession crises, recurring periods of instability leading to civil wars and fragmentation.
The book uniquely examines the inherent contradictions of dynastic power, arguing that the pursuit and maintenance of such power, while intended to ensure stability, often leads to long-term instability. This is due to the suppression of dissent, concentration of resources, and cyclical succession crises.
Through case studies ranging from the Roman Empire to European monarchies, the book offers a comparative analysis of diverse dynastic systems. It progresses by first establishing a theoretical framework, then moves to specific historical examples, comparative analyses, and finally, the long-term consequences of dynastic systems.
