Manoralism is the economic and political relations between landlords and their peasant laborers. Consequently, it's easy to understand how this is one part of a building block for the basic political and societal structure of medieval times. In addition, another part of the building block was fuedalism. This social organization created by exchanging grants of land in return for loyalty and military service would also become a foundation during these times.

Eventually, this would lead to a population growth, which would in turn spur the economy. With the increase in population came the increase in new markets. Growing trade then allowed for new towns to expand. Consequently, landlords wanted to cultivate more land so they needed the serfs, who were then given some freedom and many became free peasants. The pace of this economic life created less rigid social structures and more commercial, market oriented economies. Lastly, urban areas developed and literacy, language, new religions and education increased. All of which profoundly impacted the social structure of these times.

It was a powerful tool for a king to use because the king could make political alliances and arrange marriages to enlarge their estates.
