Gautier’s Ten Commandments of chivalry are:
Thou shalt believe all that the Church teaches and thou shalt observe all its directions.
Thou shalt defend the Church.
Thou shalt respect all weaknesses, and shalt constitute thyself the defender of them.
Thou shalt love the country in which thou wast born.
Thou shalt not recoil before thine enemy.
Thou shalt make war against the infidel without cessation and without mercy.
Thou shalt perform scrupulously thy feudal duties, if they be not contrary to the laws of God.
Thou shalt never lie, and shalt remain faithful to thy pledged word.
Thou shalt be generous, and give largesse to everyone.
Thou shalt be everywhere and always the champion of the Right and the Good against Injustice and Evil.[14]
Though these ten commandments are often accepted to be what knights would use, they would not necessarily be what a knight actually followed in the medieval era. This code was created by Leon Gautier in 1883, long after the knight had ceased to exist in its traditional form. Chivalry in a historical sense was more of a subjective term, these laws would likely be seen as a good code for a clergyman, however, others would hold different ideas on what chivalry truly was.
