The year was 73 B.C. Rome was stirred with the news of a vast gladiator army running free through the Italian countryside. For centuries the Romans had held gladiator competitions, pitting men against animals as well as other men. Gladiators were usually drawn from slaves, people whom the Romans captured in their various conquests. Today one of the most iconic and recognizable monuments of Rome are the remains of the Roman Colosseum, where perhaps thousands perished in the name of blood sport.
