What era were the samurai in?

The samurai were prominent during the feudal era of Japan, which is typically considered to span from the late 12th century to the 19th century. This period includes the Kamakura (1185-1333), Muromachi (1336-1573), and Edo (1603-1868) periods, during which the samurai served as the military nobility and enforced the social order. The samurai class was formally abolished in the late 19th century during the Meiji Restoration, which marked the transition to a modern nation-state.
