Okay kiddo, so first let's talk about what gypsies are. They are a group of people who travel around a lot and don't have a permanent home. They have their own language and culture and like to keep to themselves.
Now, the king of the gypsies is like the leader of the gypsies. You know how sometimes you play a game with your friends and one person is the leader and tells everyone else what to do? It's kind of like that.
But being the king of the gypsies is a big deal because they don't have a country or government of their own. So the king has to make sure everything is going okay and help settle any disputes that come up. It's a big responsibility!
Some gypsy groups have their own king, but there isn't one king of all gypsies. It's more like each group has their own leader, kind of like how different schools have their own principals.
Does that make sense, kiddo?
