Central government was largely reestablished by Oda Nobunaga and Toyotomi Hideyoshi during the Azuchi–Momoyama period. Although a start date of 1573 is often given, in more broad terms, the period begins with Oda Nobunaga's entry into Kyoto in 1568, when he led his army to the imperial capital in order to install Ashikaga Yoshiaki as the 15th, and ultimately final, shōgun of the Ashikaga shogunate, and it lasts until the coming to power of Tokugawa Ieyasu after his victory over supporters of the Toyotomi clan at the Battle of Sekigahara in 1600. Tokugawa received the title of shōgun in 1603, establishing the Tokugawa shogunate. The Edo period from 1600 to 1868 characterized early modern Japan. The Tokugawa shogunate was a feudalist regime of Japan established by Tokugawa Ieyasu and ruled by the shōguns of the Tokugawa clan. The period gets its name from the capital city, Edo, now called Tokyo. The Tokugawa shogunate ruled from Edo Castle from 1603 until 1868, when it was abolished during the Meiji Restoration in the late Edo period (often called the Late Tokugawa shogunate). Society in the Japanese "Tokugawa period" (Edo society), unlike the shogunates before it, was based on the strict class hierarchy originally established by Toyotomi Hideyoshi. The daimyōs (feudal lords) were at the top, followed by the warrior-caste of samurai, with the farmers, artisans, and traders ranking below. The country was strictly closed to foreigners with few exceptions with the Sakoku policy. Literacy among the Japanese people rose in the two centuries of isolation. In some parts of the country, particularly smaller regions, daimyōs and samurai were more or less identical, since daimyōs might be trained as samurai, and samurai might act as local lords. Otherwise, the largely inflexible nature of this social stratification system unleashed disruptive forces over time. Taxes on the peasantry were set at fixed amounts which did not account for inflation or other changes in monetary value. As a result, the tax revenues collected by the samurai landowners were worth less and less over time. This often led to numerous confrontations between noble but impoverished samurai and well-to-do peasants. None, however, proved compelling enough to seriously challenge the established order until the arrival of foreign powers. Korean dynasty In 1392, General
