 The foundation of Thurii is assigned by Diodorus to the year 446 BC; but other authorities place it three years later, 443 BC, and this seems to be the best authenticated date.The protection of the Athenian name probably secured the rising colony from the assaults of the Crotoniats, at least we hear nothing of any obstacles to its progress from that quarter; but it was early disturbed by dissensions between the descendants of the original Sybarite settlers and the new colonists, the former laying claim not only to honorary distinctions, but to the exclusive possession of important political privileges.These disputes at length ended in a revolution, and the Sybarites were finally expelled from the city.
