The Code of Chivalry
Chivalry, or the Chivalric Code, is the traditional code of conduct associated with the medieval institution of knighthood. Essentially, a chivalric knight is a Christian military soldier. Chivalry arose from an idealized German custom. It was originally conceived of as an aristocratic warrior code — the term derives from the French term for horseman — involving honor, gallantry, and individual training and service to others. Over time its meaning has been refined to emphasize more ideals such as knightly virtues, honor, courtly love, courtesy, and less martial aspects of the tradition.
The Code of Chivalry can be summarized in ten "commandments":
The Knight's Code of Chivalry was a moral system that stated all knights should protect others who can not protect themselves, such as widows, children, and elders. All knights needed to have the strength and skills to fight wars in the Middle Ages. Knights not only had to be strong but they were also extremely disciplined and were expected to use their power to protect the weak and defenseless. Knights vowed to be loyal, generous, and "of noble bearing". Knights were required to tell the truth at all times and always respect the honour of women. Knights not only vowed to protect the weak but also vowed to guard the honor of all fellow knights. They always had to obey those who were placed in authority and were never allowed to refuse a challenge from an equal. Knights lived by honor and for glory. Knights were to fear God and maintain His Church. Knights always kept their faith and never turned their back on a foe. Knights despised pecuniary reward. They persevered to the end in any enterprise begun.
