What was the knights obligation to the lord?

Knights had a primary obligation to provide military service to their lord, typically serving for a specified number of days each year in exchange for land or financial support. This service included defending the lord's territory and participating in battles or campaigns as needed. Additionally, knights were expected to demonstrate loyalty and uphold the lord's honor, often participating in courtly duties and supporting the lord in various capacities. In return, lords granted knights land (fiefs) and protection.
