The economic and political system of feudalism arose after the fall of the Roman Empire. In the political and military vacuum created by Rome’s fall from power, there was a large number of people and groups contending for power. It was a time of brutal violence and great instability. To try to create stability, various rulers began to offer portions of land, or “fiefdoms,” to lesser rules, who could then have serfs work the land to provide food and income. The system of feudalism was effective because it promoted stability in a very violent time and offered protection in exchange for loyalty and subservience.
