How were the samurai and daimyo related?

The samurai were the warrior class in feudal Japan, serving as military retainers to the daimyo, who were powerful landholding lords. The daimyo provided land and protection to the samurai in exchange for their loyalty and military service. This relationship was based on a feudal system where the samurai upheld the honor and interests of their daimyo, often engaging in battles to expand or protect their lord's territory. Thus, the samurai and daimyo were interconnected through a bond of loyalty, service, and mutual benefit.
