The pivotal conflict that induced the rise of feudalism in medieval Europe was the fall of the Roman Empire. Following the Empire’s collapse, societal structures eroded, leading to a power vacuum. Local lords began to consolidate power and resources, establishing a hierarchical system based on land ownership and loyalty. Feudalism emerged as a means of providing security and stability amidst chaos, with vassals receiving land in exchange for military service. This system resulted in rigid social classes and governance by local authorities, significantly influencing the political and economic landscape of medieval Europe for centuries.
