Okay kiddo, let me explain what an Edict of Toleration is in a way a five-year-old can understand!
Picture this: You have a bunch of friends who all like different toys. One friend likes cars, another likes dolls, and another likes action figures. But, sometimes they argue because they don't all like the same toys.
Now, imagine if a grown-up came in and said, "Hey, it's okay for you all to like different toys! You don't have to argue about it anymore!" That grown-up is kind of like the ruler of a country or empire.
An Edict of Toleration is like that grown-up's announcement. It's a special order that says everyone in the country or empire is allowed to have their own beliefs and opinions, even if they're different from other people's beliefs or opinions.
Sometimes, in the past, rulers or leaders didn't let people practice their own religion or beliefs. They may have punished people who didn't believe the same things as the ruler or leader. But with an Edict of Toleration, everyone can believe in what they want without fear of punishment.
So, that's what an Edict of Toleration is! It's like a grown-up telling all their friends that it's okay to like different things and they don't have to argue about it anymore.
