Okay kiddo, so you know that in England, they have a royal family, right? And the Queen is like the leader of the family. But when the Queen can’t be the leader anymore, maybe because she’s very old or sick or something, somebody else has to take her place. This is called succession to the British throne.
But it’s not just anybody who can take the Queen’s place. There are rules and laws that say who gets to be the next leader of the royal family. These rules say that the Queen’s oldest son, Prince Charles, will be the next leader when the Queen can’t be anymore. That means he’ll be the king!
But wait, there’s more! If Prince Charles can’t be the king for some reason, like if he dies or decides he doesn’t want to be king anymore, then his oldest son, Prince William, will become the king instead of him! And if William can’t be the king for some reason, then it’ll be his oldest son, Prince George, who will be the next king.
So, basically, the rules say that the people who get to be the leaders of the royal family are the Queen’s children first, then her grandchildren, and so on. And if there’s nobody left in the family to be the leader, then the rules might change or something different might happen, but we don’t need to worry about that for now.
