Knights were very highly trained soldiers who lived by thecode of chivalry. Examples of the code involved not picking onanything weaker or littler then themselves, protecting womenand children, and always being loyal. These were just a few of the laws that they lived by.
The knights armor changed dramatically through the years and by the end were very, very heavy. It was hard to believe that men could actually fight with all of this equipment. First they wore a quilted coat for padding and protection against the heat that would be made from the hot sun touching the metal. Then they wore chain mail and metal plates . Last of all they would wear full metal armor that equaled about 80-120 pounds. To tell the knights apart they would wear a coat of arms that had their names on it.
A quintain was used for training the knights. Other devices used back then for fighting included maces, battering ram, siege tower, and a battering ram.
