The gens Cassia was a Roman family of great antiquity. The earliest members of this gens appearing in history may have been patrician, but all those appearing in later times were plebeians. The first of the Cassii to obtain the consulship was Spurius Cassius Vecellinus, in 502 BC. He proposed the first agrarian law, for which he was charged with aspiring to make himself king, and put to death by the patrician nobility. The Cassii were amongst the most prominent families of the later Republic, and they frequently held high office, lasting well into imperial times. Among their namesakes are the Via Cassia, the road to Arretium, and the village of Cassianum Hirpinum, originally an estate belonging to one of this family in the country of the Hirpini.
