The empire characterized by its feudal system and samurai warriors is the Japanese Empire, particularly during the feudal period known as the Sengoku period (15th to 17th centuries). This era saw the rise of powerful daimyōs (feudal lords) who ruled over territories with loyalty to the shogun. Samurai, as the warrior class, held a code of honor known as Bushido and played crucial roles in maintaining order and executing the will of the daimyōs. The system was highly hierarchical, defining social structure, governance, and cultural practices in Japan until the Meiji Restoration in the late 19th century.
