What factors contributed to the weakening and decline of medieval Europe?

My answer:
In the 14th century, there were many factors that weakened and contributed to the decline of Medieval Europe. The peasants of the land went to decline; they had realized that they didn't have to work constantly, and be under the law of the authority of the land. In exchange, they then moved into towns where they could become free. Then, the black death had washed over everyone in Europe. making labor in the land desperately needed. Feudalism in Medieval Europe was over by the time that King Henry the 8th clashed with the Pope. And as a result, England declined from the catholic church of central Rome.

I think you're missing some things/events that really contributed to changes in life in the 1400s and afterward.

~ Invention of the printing press
~ Martin Luther's 95 Theses (nailed up on a church door!)
~ Literacy rate began to climb once there were Bibles in print.
~ Catholic Church began to be seen very differently once people could read the Bible for themselves
~ Artists and architects began to branch out and work in non-religious themes and realms.
... and many others.

To elaborate on the factors that contributed to the weakening and decline of medieval Europe:

1. Decline of the Peasantry: The serfs, who were bound to the land and obligated to serve the nobility, started to realize that they had alternatives. The growing availability of opportunities outside of agricultural work led many peasants to abandon their obligations and move to towns, where they could enjoy more freedom and become economically independent. This shift weakened the agricultural system that relied on peasant labor, impacting the feudal structure of medieval society.

2. The Black Death: The bubonic plague, commonly known as the Black Death, struck Europe in the mid-14th century. This pandemic had a devastating impact, wiping out a significant portion of the population. The loss of lives caused an acute labor shortage, disrupting agricultural production, trade, and overall economic stability. The scarcity of labor, coupled with the sudden decrease in demand, led to a decline in agricultural productivity and weakened the overall economy of medieval Europe.

3. Decline of Feudalism: Feudalism, the social, political, and economic system that characterized medieval Europe, gradually lost its hold during this period. The rise of centralized monarchies led by powerful kings, like King Henry VIII of England, challenged the authority of feudal lords and the Church. The conflicts between monarchs and nobility, as well as religious disputes such as the Protestant Reformation, fragmented the power structures of medieval Europe. As a result, feudalism lost its effectiveness as a governing system.

4. Fragmentation and Decline of the Catholic Church: The authority of the Catholic Church, which held significant influence over people's lives and played a central role in medieval society, also weakened. The Protestant Reformation, initiated by Martin Luther in the early 16th century, challenged the Church's teachings and practices. The subsequent religious conflicts and divisions further weakened the Church's power and authority, leading to a decline in its socio-political influence.

These factors, among others, played a significant role in the weakening and decline of medieval Europe. It is important to note that this period also marked the transition to the Renaissance and the beginnings of modern Europe.
