The first full study of the most remarkable history of the early popes and their relationship with Rome, the Liber pontificalis.

Valla (1407-1457) was the most important theorist of the humanist movement. His most famous work is the present volume, an oration in which Valla uses new philological methods to attack the authenticity of the most important document justifying the papacy's claims to temporal rule.

When the British thought of themselves as a Protestant nation their natural enemy was the pope and they adapted their view of history accordingly. In contrast, Rome's perspective was always considerably wider and its view of Britain was almost invariably positive, especially in comparison to medieval emperors, who made and unmade popes, and post-medieval Frenchmen, who treated popes with contempt. As the twenty-first-century papacy looks ever more firmly beyond Europe, this new history examines political, diplomatic and cultural relations between the popes and Britain from their vague origins, through papal overlordship of England, the Reformation and the process of repairing that breach.
