Caliphate: The History of an Idea

What is a caliph? Is it a religious office, a political title, or something in between? For over thirteen centuries, Muslims have debated this question, and the answers have shaped empires, revolutions, and the modern Middle East. Hugh Kennedy tells this epic story with unmatched clarity and authority.

Caliphate: The History of an Idea is a landmark work by one of the world’s foremost historians of the Islamic world. Hugh Kennedy traces the evolution of the caliphate from its origins in the tumultuous years after the Prophet’s death in 632 to its modern‑day incarnations and distortions.

The book is structured chronologically and thematically, covering:

• The “Rightly Guided” caliphs and the early debates over succession
• The Umayyad dynasty in Damascus and the shift to hereditary rule
• The Abbasid revolution and the golden age of Baghdad
• The fragmentation of political power and the rise of rival caliphates (Fatimid, Umayyad in Spain)
• The Ottoman claim to the caliphate and its role in the empire’s legitimacy
• The abolition of the caliphate in 1924 and the colonial manipulation of the idea
• The resurgence of caliphate rhetoric in modern Islamist movements, including ISIS

Kennedy shows that there has never been a single, fixed definition of caliphate. Instead, the concept has been constantly debated, adapted, and sometimes weaponized. He contrasts the tolerant, pragmatic rule of early caliphs like ʿUmar with later authoritarian and utopian visions, and exposes how modern extremists have selectively mined history to justify violence.
