The Thirteenth-Century Inter-Lordly System.

This book offers a pioneering answer to a puzzle shared by scores of medieval historians: how to make sense of the late medieval inter-lordly politics? Taking the Angevin-Piast dynastic marriage of 1320 as a case study, Kozłowski surveys international politics in Latin Christendom across the 13th century in a powerful attempt to develop and substantiate an alternative approach to medieval politics. Drawing on IR theoretical discourses and exploring essential elements of medieval political culture, the book introduces a concept of “lordly identity” as an analytical tool for determining lords’ political motivations, and discusses the basic structure of a system, wherein inter-lordly relations occurred.
