Which code instructed loyalty of samurai to their daimyo?

The Bushido code was a set of ethical principles followed by the samurai that emphasized loyalty to their daimyo (feudal lord) above all else. This code governed the behavior and mindset of samurai warriors, who were expected to serve their daimyo faithfully and to prioritize their lord's needs and wishes over their own personal interests. Adherence to the Bushido code was seen as a way for samurai to demonstrate their honor, courage, and commitment to their feudal obligations.
