History of Japan
During the Edo period, Japan had many small rulers. There were about 200 of them. They were called daimyo, and they were all ruled by the Tokugawa shogunate which was leaded by the Tokugawa clan. The shoguate's capital was relocated to Edo. This place was at modern-day Tokyo. Fifteen shoguns controlled the Tokugawa shogunate during the Edo Period.
