Feudalism emerged in Western Europe as a response to the collapse of centralized authority following the fall of the Roman Empire. As Roman institutions crumbled in the 5th century, Europe descended into a period of instability and fragmentation. Without the protection and infrastructure once provided by Rome, people turned to local leaders for safety and organization. These leaders—often wealthy landowners or military figures—became the foundation of a new social and political structure that emphasized land ownership, loyalty, and mutual obligation.

The early roots of feudal practices can be traced to the relationships that formed during this chaotic period. In the absence of a strong central government, powerful individuals began offering protection to those around them in exchange for service or labor. Over time, this informal system developed into a structured hierarchy, with clearly defined roles and responsibilities. Lords granted land, known as fiefs, to their vassals, who in return pledged loyalty and military support. This mutual dependency became the backbone of medieval society and formalized the relationships that had organically formed during the earlier periods of uncertainty.

Localized power became the defining feature of feudal Europe. With no single empire to unify the continent, authority became decentralized. Kings often ruled in name only, while real control rested in the hands of regional lords and nobles. These lords governed their own territories, enforced laws, and maintained private armies. In turn, they depended on the support of lesser vassals and knights, who managed smaller portions of land and fulfilled military duties. This layered structure ensured that each level of society relied on those above and below, creating a rigid yet stable social order.
