TRUE or FALSE Feudalism concerned the lower classes?

TRUE! Feudalism is a series of complicated lord-and-vassal relationships between nobles, but the living conditions of serfs under the feudal system are hugely important to Western history. The overall squalor of the lives of the serfs (lower classes) contributed to the rapid spread of diseases like the black plague, the eventual re-emergence of major population centers, and the prevalence and importance of the Catholic church.
