Nikephoros I ruled the Eastern Roman Empire, now usually called Byzantium. The campaign account comes mainly from Theophanes, who is critical of the emperor. Taking the capital did not settle the war: Bulgar resistance continued. The proposed area of the defeat is not a securely identified map point. Led the Byzantine campaign in 811. His army captured and burned Pliska. Died when the retreating army was defeated. His campaign distinguishes capturing a capital from achieving a lasting military victory.
