The Eighteen Christian Centuries

A chronological survey traces Christianity's development and its interaction with political, legal, and cultural institutions from the early Roman period through the early modern age. Presented as consecutive century-by-century chapters, it outlines imperial governance and persecutions, the church's establishment and spread, the transformation of Roman structures into medieval polities, the growth of papal and monastic influence, the emergence of feudal and scholastic orders, military and doctrinal conflicts, and later reformations and state-centered religious changes. Emphasis rests on institutional continuities and disruptions, major movements and controversies, and lists of notable figures and dates to orient the reader.
