Knights were peasants' overlords. Peasants owed them service (they would farm and work for them) in return for their land. Peasants were effected by what kind of overlord the Knight was, whether he was fighting, meaning he was away, or saving up to go on crusade, meaning he might need more money.
Some knights were called sirs as they were knighted by a king/Queen for different reasons.
