Syagrius
Syagrius (died 486/487) was the leader of an isolated Roman community based in Soissons which still existed after the Roman empire lost control over the region around it. Modern historians refer to his state as the Kingdom of Soissons, because the 6th-century writer, Gregory of Tours referred to Syagrius as a "King of Romans" (Latin: rex Romanorum), while the Chronicle of Fredegar calls him a Roman patrician.
