Okay kiddo, let me explain to you about what happened long, long ago in Ancient Rome. You know how we live in a place where we can believe in whatever religion we want and nobody can hurt us for it, right? Well, it wasn't always like that in Rome. In those days, people believed in a variety of gods and goddesses and some of them were different than what others believed.
People who followed religions that were different from the ones that the rulers followed were often not liked very much. They were accused of being bad people or even trying to cause problems for the government. Sometimes, people who had powerful positions in the government even made laws that made it illegal for people to believe in certain religions. This meant that if you were someone who believed in a religion that was not approved of, you could get in trouble with the law.
The punishment for breaking these laws could be really scary. Sometimes, people were thrown in jail or even killed for believing in a different religion, and this happened to many people. Christians, for example, were one group who were persecuted because they believed in only one god, while the rulers believed in many. This happened over a very long period of time and sometimes got better, but sometimes got worse.
It's really hard for us to imagine what it was like because we are so lucky to have the freedom to choose what we believe in. The world has changed a lot since then, and now we have many rules that protect our right to believe what we want, but we must always remember that this wasn't always the case, and we should be grateful we have these rights today.
