Provides a theoretically guided and historically sensitive account of the geopolitical relations of medieval Latin Christendom. This book develops an historically sensitive conceptual framework for understanding geopolitical conflict and war more generally.

Viewing the late Middle Ages (1250-1550) through the lens of what he calls the "historical structure of war", Andrew Latham provides a fresh conceptualization of the geopolitics of late medieval Latin Christendom, emphasizing neither "feudalism" nor "heteronomy", but rather the emergence of the "corporate-sovereign state", the "corporate-sovereign Church" and "Hobbesian-Lockean anarchy". He goes on to demonstrate how this distinctive historical structure of war gave rise to a constellation of public and religious wars that was unique to late medieval Latin Christendom.

"Latham's book deserves a wide readership. It is the first of its kind to engage with a literature that is probably unfamiliar to most students of international relations. It integrates historical interpretations of medieval politics with reflections on principal theories of international relations, and specifically with constructivist scholarship. ... Not the least of the reasons for welcoming this study, which is a courageous and innovative one by any standard, is that it stimulates large questions about the relationship between the medieval and modern international orders and about how to characterise and explain the main continuities and discontinuities. Theorising Medieval Geopolitics is essential reading for those who are interested in the historical development of the modern European state and states-system. It is invaluable for those who wish to understand what is at stake theoretically in attempting to understand the relationship between the 'medieval' and 'modern' eras." - Andrew Linklater, Aberystwyth University, e-International Relations
