The term "Samurai" refers to a member of the Japanese warrior class that existed from approximately 12th century until the mid-19th century. The Samurai were known for their strict code of honor, called Bushido, which emphasized virtues such as courage, loyalty, and self-discipline. They served as military officers and administrators in Japan's feudal society, and many became skilled warriors who devoted themselves to the art of swordsmanship. The Samurai played a significant role in Japanese history, particularly during periods of civil unrest and political upheaval.
