Between the 3 rd and 4 th centuries, barbarian tribes seeking more regular food sources and better climate began to rapidly expand and began to migrate further to Europe. During this period, conquest of barbarians and immigrants made the savage tribe customs and traditions the foundation of European society. Most of these tribes are Germanic and the most influential tribe is the Frank tribe. In 486 Frankish Chish Clovis defeated the last Roman governor Gaul and founded Frank Kingdom in Europe.
Charlemagne was born in 742 and ruled the Kingdom of Frank from 800 to 814. Charlemagne is the son of King Pepin, which was regarded as the founder of the Carolingian dynasty. The control of Charlemagne in Western Europe is remembered today for expansion and unification throughout the region. After the collapse of the Western Roman Empire, the Frank empire under the rule of Charlemagne was one of the first countries to take over the role as the leading and leading powerhouse of Western Europe. Charlemagne extends his influence and the power of Frankish Empire to most of Western Europe and Central Europe. He also has the responsibility to successfully conquer a part of Italy.
In the year 742 AD, Charlemagne (768 - 814) became the ruler of the Kingdom of Frank. During his reign, the Frank empire, including northern Italy, France and Central Europe, had a larger total area than the Roman Empire. In 800 years, this powerful ruler crowned as a Holy Roman emperor. Charlemagne is considered to have introduced a new way of working in society. This system is called the feudal system. Charlemagne dominated Frankish Empire by providing land to those who promised to be true to him. He also helped the Frank tribe become leaders of the church bishops, counties, aristocratic families. This concept of supporting the king in exchange for land and benefits is thought to lay the foundation of feudalism. This early social order introduced by Charlemagne later spread throughout Europe during Europe.

The feudalism of Western Europe appeared in the 9th century and the Frankish empire of the 10th century. It appeared because they were able to gain ownership of the land after Frank and soldiers settled. And feudalism is a viable alternative to the new social environment as the social structure of the era before Rome has collapsed in Western Rome. That is why it spread rapidly to other parts of Europe. After the William conquerors invaded Norman in the 11th century, UK feudalism was brought to this country. After the invasion, William replaced Norman French nobility who started using feudalism and the popular Anglo-Saxon aristocracy. After conquest, William occupied all the land of England and then divided it into his own soldier and aristocrat. In the feudal system, farmers can acquire land ownership and cultivate and live to provide landowners' labor.
