Why did samurai go to war?

Samurai went to war primarily to uphold their honor, loyalty, and the feudal obligations to their daimyo (feudal lords). Warfare was often driven by the need to defend territory, expand influence, or settle disputes among rival clans. Additionally, engaging in battle provided opportunities for personal glory and the demonstration of martial skills, which were central to a samurai's identity and code of conduct known as bushido. Ultimately, war was a means of maintaining social order and reinforcing the hierarchical structure of Japanese society.
