"Chariot racing was the oldest entertainment in Rome. It was also the most popular venue by far. Chariot racing dated all the way back to the monarchy and founding of Rome. The Greeks also held chariot races and had a large influence on the Roman tradition. Chariot racing was not the only event held in the circuses. Wrestling and gladiator combats were also held in some cases, but chariot racing was the most common."
