Question

Why was feudalism developed?

A. There was a need for a clear successor to the crown.
B. Centralized power was lost in the face of invasion.
C. The church was losing power and failed to protect the lords.
D. Lords decided to reform society by establishing chivalry.

Answer 1

I believe it is B

Step-by-step explanation:

Because it is when the nobility held lands from the Crown in exchange for military service, and vassals were in turn tenants of the nobles and it would only really be needed in a time of war or an invasion.
