The fall of the Roman Empire in 476 AD made a political vacuum in Europe. There was rigorous political turmoil in the Western Europe. The invasions of Magyars, Vikings and Muslims caused great horror in Europe. The central authority became useless and people start to look for the protection towards the local rulers who could fight the invaders. These people who had local armies gained the political strength. The foreign invasions of Europe can be cited between 850-950 AD. In the midst of this turmoil arose the system of feudalism where lands were controlled by the feudals. The system was mainly based on mutual obligations. The feudal would provide military protection and land or fief to the vassals. As an outcome, the ordinary people got protection from the invaders. The vassals were bound to propose services as knights. The castles of these Lords were termed as manors. These lords themselves might become the vassals of a great Lord. In a completed feudal system, the king was at the top with his lands and under him were vassals up to the peasants who were serfs. The peasants were responsible for giving food to the Lord. In short, feudalism touched political, social and economic life of the Europe throughout the middle ages.
