2. what responsibilities did knights have in the feudal system?

the feudal system worked through a series of exchanges. kings received loyalty from their nobles, protection from the knights, and food/services from the peasants. they gave land to the lords, which they could rule as manors with employable knights and peasants in the surrounding countrysides.

maybe you need to work on the pipes in the house. i am just saying this because you did not give any details.

herodotus taught this. herodotus was an ancient greek historian who was born in halicarnassus in the persian empire. he is known for having written the book the histories, a detailed record of his "inquiry" on the origins of the greco-persian wars.
