Answer:
1. Hundred Years' War 2. Bubonic Plague 3. Politics/Magna Carta
Explanation:
1. Hundred Years' War
In order to succeed, feudalism needed lots of manpower. Vassals and serfs worked the manor, bound by law to a lifetime of labor until war broke out between England and France in 1337. This marked the start of the Hundred Years' War.
2. Bubonic Plague
The bubonic plaque was a deadly and highly contagious disease that caused millions of deaths. Ten years after the Hundred Years' War began, the plaque spread like wildfire. The bubonic plaque claimed at least a third of Western Europe's total population. The conditions were so bad that laborers ran away to larger cities, an act that would have once been punishable by law.
3. Politics/Magna Carta
Feudalism was a insistent system that granted very few individual liberties. Ancient laws forced peasants to land, making their labor obligatory. However, over time, concepts of individual rights gained traction. The 12th century reforms of Henry II, for instance, expanded the legal rights of a person facing trial. In 1215, King John was forced to approve the Magna Carta, a document obligating the crown to uphold common law.
