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.
Shinto The Meiji Restoration reasserted the importance of the emperor and the ancient chronicles to establish the Empire of Japan, and in 1868 the government attempted to recreate the ancient imperial Shinto by separating shrines from the temples that housed them. During this period, numerous scholars of kokugaku believed that this national Shinto could be the unifying agent of the country around the Emperor while the process of modernization was undertaken with all possible speed. The psychological shock of the Western "Black Ships" and the subsequent collapse of the shogunate convinced many that the nation needed to unify in order to resist being colonized by outside forces.
