Okay, so imagine you and your friends are playing a game, and one person is in charge of keeping track of the rules and making sure everyone plays fair. This person is called the Praetor.
In ancient Rome, the Praetor was someone who had a really important job. They were a judge who helped keep order and make important decisions about legal cases. They were kind of like the boss of the court.
When someone had a problem, like maybe their neighbor was being mean and wouldn't give back their ball, they could go to the Praetor and ask for help. The Praetor would listen to both sides and then make a fair decision about what should happen next.
So, in short, the Praetor was someone who made sure that everyone played by the rules and helped keep things fair and just in ancient Rome.
