There were many reasons for the downfall for the Middle Ages, but the most crucial ones were the decline of the feudal system, and the declination of the Church's power over the nation-states. In feudal society, everyone had a definite place and a definite role, with the power resting in the hands of the local lords (instead of a central government). The lords, or nobles, lost power after the Crusades, when the Europeans came into contact with the more advanced civilizations of the Byzantine Empire and the Muslims. That spurred the growth of trade, which in turn gave rise to a money system. The money system in turn caused the birth of a middle class, which didn't fit anywhere into the feudal system. It was made up of the serfs and peasants that left the feudal system in search of making money in trade. For the middle class, the king granted

While t his money economy grew, the feudal lords were put into an economic squeeze. As one may see, that didn't leave much of a place for the nobles, who were rapidly losing power. Another thing that contributed to their loss of power was the enforcement of Common Law, which applied throughout the kingdom.

Conflicts between the papacy and the monarchy over political matters resulted
