Battle of Achelous (Byzantine Empire vs Bulgarian Empire)

The Battle of Achelous between forces of Eastern Roman Empire (Byzantine Empire) and Bulgarian Empire took place on 20 August 917, on the Achelous River near the Bulgarian Black Sea coast. The battle, which was one of the biggest and bloodiest battles of the European Middle Ages, was one of the worst disasters ever to befall a Eastern Roman army, and conversely one of the greatest military successes of Bulgaria. The Bulgarians obtained a decisive victory which not only secured the previous successes of Simeon I, but made him de facto ruler of the most of the Balkan Peninsula. Some of the significant consequences of the battle was the official recognition of the Imperial title of the Bulgarian monarchs as Tsar (Caesar), and the affirmation of Bulgarian Tsar equality vis-à-vis with Eastern Roman Emperor.
