後醍醐天皇
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.
