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.
