The importance of the emperor: Lothar I and the Frankish civil war, 840–843

Lothar I's perspective on the Frankish civil war has not previously been explored. Close analysis of the distribution and wording of the most significant body of evidence produced by Lothar's circle, his charters, casts new light on the politics of the civil war. The imperial title and questions of legitimate inheritance emerge as factors of crucial importance, which shape not only Lothar's self-presentation in the charters, but also Nithard's influential account of the war, and negative portrayal of Lothar.
