Topic - Medieval Times

For our topic we have been learning about the medieval times. There was a rank of power and obviously the King was on top. Then came the Bishop and Baron, they both have the same amount of power. The Knights then come then Merchants. Then at the bottom are peasants. But I would also want to learn about the sports they played back then. For example jousting, gladiators and sword fighting and a lot more. And for fun activities I don't really have any great ideas.
