The Battle of Tolbiac was fought between the Franks, who were fighting under Clovis I, and the Alamanni, whose leader is not known. The date of the battle has traditionally been given as 496, though other accounts suggest it may have been fought in 506. The site of "Tolbiac", or "Tulpiacum", is usually given as Zülpich, North Rhine-Westphalia, about 60 km east of what is now the German-Belgian frontier. The Franks were successful at Tolbiac and established their dominance over the Alamanni.
