Nationalism was everywhere in the 19th century, and people all over the world carved new nation-states out of old empires. Nationalist leaders changed the way people thought of themselves and the places they lived by reinventing education, military service, and the relationship between government and governed. In Japan, the traditional feudal society underwent a long transformation over the course of about 300 years to become a modern nation-state. Host John Green follows the course of Japanese history from the emergence of the Tokugawa Shogunate to the Meiji Restoration. He also covers nationalism in many other countries along the way.
