It was the lords responsibility to manage his land and defend his land and the people who worked it. The lord appointed knights to make sure villagers carried out their task, which included farming for the lords, land and paying rent in the form of crops. Lords are also acted as judges in manor courts and had the power to fine and punish those who disobeyed the law. Some lords held post in the kings government in times of war lords fought for their own higher ranking lords or at least supplied them with a well trained fighting force.
