Describe how the feudalism works, and explain how it began, following the fall of rome

Feudalism is a system of land ownership and duties. ... With feudalism, all the land in a kingdom was the king's. However, the king would give some of the land to the lords or nobles who fought for him. These gifts of land were called manors. Feudalism arose in Europe because of the need for a way to pull society back together after the Roman Empire collapsed in the West. ... In feudalism, a leader “owned” the service of his followers. They had to help him militarily whenever he asked. In return, they were given power over certain areas of land.During the years of the Roman Empire, the poor people were protected by the soldiers of the emperor. When the empire fell, there were no laws protecting them, so they turned to the lords to keep the peace and to act on their behalf. This willingness to be ruled by the lords led to the beginnings of feudalism.
