What was the main obligation a knight owed to the lord from whom he held land?
Բացատրություն
The whole point of granting land to a fighting man was to have soldiers on call, so his duty was to turn out armed, with his own horse and equipment, for a customary period whenever the lord summoned him. The idea of unlimited lifelong service fails because custom set a firm limit, and a lord who wanted men beyond it had to pay them or bargain for it.
