What was the feudalism of Knights and samurai?

Feudalism of knights in medieval Europe and samurai in Japan was a hierarchical social system where land was exchanged for loyalty and military service. Knights served lords in exchange for land (fiefs) and protection, while samurai pledged allegiance to daimyos, local warlords, receiving land and status in return. Both systems emphasized loyalty, honor, and martial prowess, with knights adhering to chivalric codes and samurai following bushido principles. Despite their cultural differences, both systems were characterized by a decentralized political structure and a focus on warrior aristocracy.
