William the Conqueror is credited with changing the common law after the Norman Conquest in 1066, which is when socially systematic feudalism in medieval England is thought to have started (Douglas 1939, 28). Under William the Conqueror, the Norman conquest of England was finished over a five-year period from 1066 CE to 1071 CE (Malmesbury 1998, 12). The Norman elite took over the country's territories after the conquest, replacing the Anglo-Saxons; the church was reorganized; and new architectural styles were adopted (Malmesbury 1998, 12). The Norman invasion marked a significant turning point in English history because of the spread of feudalism (Douglas 1939, 28). I learned that feudalism emerges in areas with a disorganized government and a high level of violence after exploring the city and attempting to blend in with various social classes (Malmesbury 1998, 12). Three distinct social classes exist in a feudal society based on the king, the noble class, which is made up of nobles, priests, and princes, and the peasant class (Douglas 1939, 28). In the past, the king owned all of the available lands and gave them to his nobles to rule (Malmesbury 1998, 13). Farmers were then rented the land by the nobles. In exchange for production and military service, the peasants paid the nobles, who in turn paid the king (Malmesbury 1998, 13). Everyone liked the king, at least on the surface, and everything was supported by the peasants' labor (Douglas 1939, 29). Peasant families that had held small farms were forced to become laborers as a result of the Norman aristocracy seizing property (Malmesbury 1998, 12). They also owed the landlords their allegiance and a portion of their harvest (Malmesbury 1998, 12). On the other hand, the Church experienced a comparable reform which led to there were only two Anglo-Saxon bishops left by 1087 (Douglas 1939, 27). William was able to exert much stronger administrative and military control over the Church throughout England by putting the bishops closer to the nation's urban populations (Malmesbury 1998, 15). Lastly, William imposed substantial taxes during his rule, and as a result, Winchester's treasury was well-stocked. Despite the fact that William offered his loyal followers land, they rarely received any political influence in return (Douglas 1939, 28). The government was not physically centralized because William wanted to roam his kingdom and frequently visit Normandy (Malmesbury 1998, 12).
