What were knights for?

Most people think that knights were just men who rode on horses all

day, but that is incorrect. The medievil knights can be compared to todays modern

tank. They were covered in multiple layers of armor and could plow through anyone

standing in their way. Knights were the wealithest of soldiers. It was expensive to be

a knight, all their armor shields and weapons cost a lot of money. The knights horse

could be compared in price to buying a small plane today.
