The correct relationship between the daimyo and the samurai is that the samurai were the vassals who worked for the daimyo.
In the feudal system of Japan, the daimyo were powerful lords who controlled large territories and had significant authority. The samurai, on the other hand, were the warrior class who served the daimyo. They pledged loyalty to their daimyo in exchange for land, protection, and the right to govern the lands they were granted. This relationship was characterized by a system of obligations and mutual support, where samurai provided military service and other assistance to the daimyo in exchange for rewards and status.
