Chariot racing was the oldest and most popular entertainment in the Roman world, dating back to at least the monarchy and in legend to the founding of Rome itself .... Chariot racing was very expensive and was run for profit as a highly organized business. There were four racing factions in Rome, the blues, greens, whites and reds, which were the colors worn by the charioteers. Successful charioteers became rich and famous, and portrayals of them in sculpture, mosaic, and molded glassware have survived, sometimes with their names. There was great rivalry among the factions, sometimes leading to violence among their supporters, but the greens and blues were usually the favorites.Barbara McManus provides a thorough account of chariot racing from its origins among the Etruscans to a description of a day at the races in the Circus Maximus. Included at her site is additional information about the chariots, charioteers, and racing factions. Go Big Blue!
