What would eventually render the feudal system obsolete explain?

The plague rendered the feudal system.

The black plague was a dangerous and notably infectious disease which influenced all of Europe. It presumably was carried to Italy on a ship, expanding North and West Europe completely, including England. This disease was induced by the bacteria from rats and fleas.  This event was declared as the "Black Death" because the inflammation on the skin was blue or black. This virus was spread from fleas and it would feed off of infected mammals like rats due to the dirty contingencies of people.

This disease transformed the feudal system remarkably. It destroyed 1/3 of the European people, and half of the Chinese people as well. The deaths of all these people influenced the commercial and political structure of Europeans, trade, and commerce diminished, and its economy needed to be reconstructed. After the plague desisted, there was a shift among the control of a common person and nobles. However various peasant uprisings were also busted out after the plague as well.
