Nagoya was a major trading city and political seat of the Owari lords, the most important house of the Tokugawa clan. They encouraged trade and the arts under their patronage, especially Tokugawa Muneharu, the 7th lord, who took a keen interest in drama and plays and lived lavishly. Under his rule, actors and actresses began to visit Nagoya. Arts and culture was further supported by the city's wealthy merchants. Culture flourished after the feudal Edo period and the beginning of the Meiji era. During World War II many old buildings and artefacts were destroyed. The region's economic and financial power in the post-war years rekindled the artistic and cultural scene.
