The Meiji Restoration (明治維新, Meiji Ishin), also known as the Meiji Ishin, Renovation, Revolution, Reform, or Renewal, was a chain of events that restored practical imperial rule to Japan in 1868 under Emperor Meiji. Although there were Emperors before Meiji Restoration, the events restored practical abilities and consolidated the political system under the Emperor of Japan.
The goals of the restored government were expressed by the new emperor in the Charter Oath. The Restoration led to enormous changes in Japan's political and social structure, and spanned both the late Edo period (often called Late Tokugawa shogunate) and the beginning of the Meiji period. The period spanned from 1868 to 1912 and was responsible for the emergence of Japan as a modernized nation in the early twentieth century.(Wikipedia)
