Answer
The Tokugawa shogunate was the ruling military government of Japan during the Edo period, lasting from 1603 to 1868. The shogun, who was the de facto ruler of the country, held the title of征夷大将軍 (Sei-i Taishōgun), "Great General Who Subdues the Barbarians". The daimyo, the powerful territorial lords, were subject to the shogun and owed him loyalty and military service.
