What was the king required to do for his Lords?

The king was required to provide protection and governance for his lords, ensuring their safety and upholding their rights within the realm. In return, the lords were expected to offer military support, loyalty, and counsel to the king. This reciprocal relationship helped maintain the feudal system, where the king relied on his lords for stability and the lords depended on the king for authority and security. Additionally, the king was responsible for administering justice and overseeing the land granted to his lords.
