Knights were specially trained fighters in the middle ages.
They were usually the sons of Lords or Kings.
They were the backbone of the medieval army.
At seven, they became pages.
They learned good manners, music, dancing, horse riding and helped the lady of the castle.
At fourteen, they became squires. They helped the Lord dress for jousts and battles.
At twenty-one, they were dubbed knights by their Lord.
The knight followed the code of Chivalry which was to promise to be truthful, generous and loyal, to be courteous to the poor and to protect women and children.
The Lords and knights divided up their land into manors.
A knight kept some of the land for his own use [called Demesne] and rented the rest to people called peasants. they were treated like servants.
The knights used bailiffs or stewards to run the manors.
