turned their attention to rebuilding, first physically, and then politically. Their political influence grew stronger through peaceful means, and the warrior monks played only very minor roles in the wars of the 13th and 14th centuries. Violent conflict between the temples still occurred on occasion, once again over political and spiritual appointments, and related matters. During the wars of the Nanboku-chō period, Mount Hiei took in the rebel Emperor Go-Daigo, and offered him sanctuary. Emperor Go-Daigo, along with his son, and the help of the sōhei of Mount Hiei, launched a brief rebellion against the Kamakura shogunate. The Ashikaga shogunate took power shortly afterwards, and supported Zen over the other Buddhist sects, drawing the ire of the warrior monks. Over the course of the 1340s–1360s a number of conflicts erupted between the Tendai sect temples, and those of Zen, especially Nanzen-ji. Sengoku-jidai and the rise of the Ikkō-Ikki The Ōnin War, starting in 1467, was the prelude to over a century of civil war in Japan, and the stimulus for a reorganization of the warrior monks. Unlike the Jōkyū War and Mongol invasions of the 13th century, the Ōnin War was fought primarily in Kyoto, and thus the warrior monks could no longer remain non-violent and neutral. In addition, a new breed of warrior monks was forming in the countryside. Where the monks of Mount Hiei had subscribed to the teachings of the Tendai sect, these new groups, calling themselves Ikkō-ikki, followed the dictates of the Jōdo Shinshū sect of beliefs. They were essentially coalitions of religious fundamentalist priests, farmers, and families, who were willing to literally fight for their beliefs. Ikkō-ikki translates to something like "devoted league", but also had the connotation of "single-minded riots". In 1488, their leader Rennyo, incited an uprising against samurai rule, and secured Kaga Province for the Ikkō-ikki. From there they spread, establishing themselves in Nagashima, Ishiyama Hongan-ji, and Mikawa Province. Their growing power base was eventually to attract the attention of warlords like Oda Nobunaga and Tokugawa Ieyasu, who recognized their opposition to samurai rule, their determination, their strength, and their numbers. Tokugawa Ieyasu attacked the Ikkō-ikki of Mikawa in 1564, in the Battle of Azukizaka, and failed to defeat the Ikkō-ikki, but returned shortly afterwards with a contingent of warrior monks from his own religious sect, Jōdo-shū, and, after defeating the Ikkō adherents in battle, burned all their temples to the ground.
