Feudalism was created in the 9th century to eliminate social chaos and bring order to social classes. Kings also used it to expand their lands. In exchange, they would get protection, money, crops and judicial duties. It was also used in war to force knights to fight. They centralized the government to organize power and land. Feudalism was used to give land by the king, organize social status and obtain military services and protection in return. Feudalism was a set of political and military customs in medieval Europe that flourished between the 9th and 15th centuries ("feudalism"). “The feudal system was not planned but rather developed and grew in response to the social chaos that followed the fall of the Western Roman Empire. He restored order where there was none and created new chains of command to replace those that had disappeared” (James 58). Feudalism was introduced by King William I into England; this system organized power, land and divided people into classes. The king, who owned all the land, gave part of it to the church and the barons in exchange for large blocks of land. The barons promised to fight for the king. Land lent to knights and also to common people (Susie 5). The test of feudalism was also to defend itself against invaders (John 32). In the absence of centralized government authority, people look to personal relationships to unite society. An individual with military might to offer offered his services to a feudal lord (Hay 170). Feudalism was created to bring order to society, land and power. In the economic system, owners forced workers to work on the lord's manor for his benefit (Medieval 65). Feudalism cultivated many aspects of Europe that remained in place (Hay 39). “The feudal system was invented by lawyers and legal historians of the 16th and 17th centuries who were investigating the origins of the most common form of noble land ownership in their time (The Brown Reference Group 64). The feudal system was used in many ways to simplify society and the country. Before the king ceded his lands to the barons, they had to take an oath of loyalty. The Nobel property was subdivided among a multitude of co-shareholders. The feudal system was based on a more or less complicated hierarchy of barons and vassals, united by bonds of homage and loyalty by a sworn oath and by certain obligations defined in the contract..
