Kingdom of Soissons
The Kingdom of Soissons is the name given by modern scholars to the fifth-century "kingdom" of Romans ruled by Syagrius, which was based in Soissons in what is now northern France. There is disagreement among scholars as to both its extent, how long it existed, and whether it was considered a kingdom by contemporaries. In one of the only mentions of him, Syagrius was referred to as "king of the Romans" by the 6th-century historian Gregory of Tours, and both he and the population he ruled are generally understood to have been Gallo-Roman.
