Samurai allows you to take control of Japan. In medieval Japan, the central government of the emperor was dissolved. He become a powerless figurehead while various clans competed to take control of the country.
These clans were similar to the noble houses of Europe; and their leaders the equivalent of medieval Dukes, Barons, Counts, and the like.
Using formldable samurai warriors, the clans waged endless wars across the major islands of the Japanese archipelago.
