The romans liked to watch gladiators for entertainment.
Gladiators were people who fought wild animals chained to stumps of wood and other gladiators but sometimes slaves. The place that gladiators fought was called an Erna but the huge one in Rome was called the coliseum. It was very dangerous because the animals were very really quite fierce. They fought tigers, lions and bears. It was very risky being a gladiator and often ended in death.
