Lit. "Warring States period." The period began with the outbreak of the Ōnin Wars (Ōnin no ran 応仁の乱, 1467-77) and lasted up to the entrance of the great unifier Oda Nobunaga 織田信長 (1534-82) into Kyoto in 1568. The term is used to refer to the Late Muromachi period *Muromachi jidai 室町時代 kōki 後期, when many areas of the country were locked in civil war. One source also suggests 1491 as a beginning for the period, that being the year in which Hōjō Sōun 北条早雲 (1432-1519) destroyed the Horikoshi 堀越. Others include with it the subsequent Momoyama period *Momoyama jidai 桃山時代. The period of 100 years (1467-1568) devastated the city of Kyoto destroying countless numbers of art treasures during the fighting. The term "Warring States" was adopted from the Chinese Zhanguo (Jp: Sengoku 戦国) period. The most memorable artistic trend of the period is the early Kano style developed by Kano Masanobu 狩野正信 (1434-1530) and Kano Motonobu 狩野元信 (1476-1559). Motonobu's greatest surviving work is at Reiun'in 霊雲院 built in 1543 in Myōshinji 妙心寺. Kano artists decorated large screens *byōbu 屏風 and sliding door panels *shōhekiga 障壁画 in shogunal residences and temples, many of which were destroyed in the century-long skirmishes mentioned above.
