The study of ideas about power in Merovingian Gaul undertaken in the book made it possible to clarify the main trends and periodization of the Romano-Germanic synthesis. Thanks to the analysis of various sources, it was possible to show: the differing perceptions of political phenomena by early medieval authors coincided as follows. During this period, power was based on agreement between rulers, nobility and church hierarchy. With the change in the historical situation in hagiographic literature, a new topos arose: the kings acquired the sacred functions of the patrons of the church. At the same time, court protocols recorded an important transformation of the political representation of the Frankish sovereigns. During the period of weakening power, the Merovingians first actualized their own role as patrons of the church, and only then - the judicial function inherent in all barbarian rulers. The book is addressed to medieval historians and a wide range of readers.
