Gratian is the single most influential figure in the history of the Western just war tradition. This is a bold claim, but it is securely based upon the fact that Gratian’s law book, the Concordia discordantium canonum “A concordance of discordant canons”, is the foundational text of the Western just war corpus. More commonly known as the Decretum Gratiani, or simply Decretum, Gratian’s law book created for the first time a truly systematic analysis of the relationship between war and justice. Furthermore, the Decretum’s influence extends far beyond the field of just war studies - it helped to shape the entire Western legal tradition.
