Jousting is likely the most famous pastime of the medieval era.
Royalty and nobility often held jousting tournaments for both their knights and those from the surrounding area. A large field would be marked off with partitions, forming the lists. A pair (or in some tournaments, several pairs) of knights would enter these lists on horseback. They would then charge at each other, attempting to knock down the other with a blunted lance. (In some tournaments, the lance was not blunted, thus creating a greater risk of death.) The first to unhorse the other was deemed the victor.
