A more thorough explanation:

Aid of the King

Aid of the King is a historical term used to describe a request made by a tenant to the king for relief from another person's demand for rent.

For example, if a tenant was unable to pay rent to their landlord, they could appeal to the king for help. The tenant would make a formal request for the "aid of the king" to avoid being evicted or facing other penalties.

Another example would be if a tenant was being charged an unfair amount of rent by their landlord. The tenant could ask the king for assistance in negotiating a fair rent or for relief from the excessive charges.

The examples illustrate how the "aid of the king" was used as a legal remedy for tenants who were facing financial difficulties or unfair treatment from their landlords. By appealing to the king, tenants could receive relief from rent demands and avoid being evicted from their homes. This practice was common in medieval England and was an important way for tenants to protect their rights and interests.
