The Azuchi–Momoyama period is the final phase of the Warring States period (戦国時代 Sengoku jidai?) in Japan. These years of political unification led to the establishment of the Tokugawa shogunate. It spans the years from c. 1573 to 1600, during which time Oda Nobunaga and his successor, Toyotomi Hideyoshi, imposed order upon the chaos that had pervaded since the collapse of the Ashikaga shogunate.
Although a start date of 1573 is often given, this period in broader terms begins with 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 – shogun of the Ashikaga shogunate. The era 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.
During this period, a short but spectacular epoch, Japanese society and culture underwent the transition from the medieval era to the early modern era.
The name of this period is taken from two castles: Nobunaga's Azuchi Castle (in Azuchi, Shiga) and Hideyoshi's Momoyama Castle (also known as Fushimi Castle, in Kyoto).
