why was the tokugawa period given its name
Edo period The Edo period (江戸時代, Edo jidai) or Tokugawa period (徳川時代, Tokugawa jidai) is the period between 1603 and 1868 in the history of Japan, when Japanese society was under the rule of the Tokugawa shogunate and the country's 300 regional daimyō. The period was characterized by economic growth, strict social order, isolationist foreign policies, a stable population, "no more wars", and popular enjoyment of arts and culture. The shogunate was officially established in Edo on March 24, 1603, by Tokugawa Ieyasu. The period came to an end with the Meiji Restoration on May 3, 1868, after the fall of Edo.
Convention of Kanagawa The final article, Article Twelve, stipulated that the terms of the treaty were to be ratified by the President of the United States and the "August Sovereign of Japan" within 18 months. At the time, shōgun Tokugawa Iesada was the de facto ruler of Japan; for the Emperor to interact in any way with foreigners was out of the question. Perry concluded the treaty with representatives of the shogun, led by plenipotentiary Hayashi Akira (林韑) and the text was endorsed subsequently, albeit reluctantly, by Emperor Kōmei.[10] The treaty was ratified on 21 February 1855.[11]
