Both systems together illustrated the legal, economic, and social aspects of the Middle Ages, were known as the guidelines for the proprietors of the time, and were closely interconnected; nevertheless, they are still known as two separate systems with a few significant disparities, mainly their distinct concepts. The primary difference between the two was that Feudalism was a diplomatic and military framework, while Manorialism was a fiscal framework for the feudal estates of society, and it did not have the military component present in Feudalism. An example of this is how Feudalism included the concept of a fief, which was the agreement between the lord and the vassal to give the vassal land and his protection in exchange for his service.
