Conquests and victories brought innumerable slaves into Rome. The slaves had no rights of citizenship. They were the private property of their owners. Slaves were also sold. Sometimes, under special circumstances, they were granted freedom. Romans at times used these Slaves as gladiators. They amused at the combat of the gladiators from the amphitheatre. A majority of slaves and prisoners lost their lives in such fights. At times the slaves also rose in rebellion.
