Takauji, who had occupied Kyōto, enthroned there a Jimyō-in prince as the Emperor Kōmyō, and established his shōgunate at Muromachi in the capital. The Emperor Godaigo shortly after repaired to Yoshino, about fifty miles south of Kyōto. For fifty-seven years subsequent to this event (1336-1393) two emperors reigned simultaneously, one at Kyōto and the other at Yoshino. The former was of the Jimyō-in line and the latter of the Daikaku-in line, now known respectively as the Northern and Southern dynasties (_hoku-chō_ and _nan-chō_).[2] It was a period of perpetual conflict between the supporters of the two imperial houses. Among the partisans of the Southern dynasty the most puissant and popular were Nitta Yoshisada and Kitabatake Akiiye, of whom the former had his headquarters in Echizen, where he guarded the heir-apparent of the South, while the latter, under the auspices of Prince Yoshinaga, held Mutsu under control. Soon, however, the armies of Ashikaga overran Echizen, and Yoshisada fell in battle. This was followed by the death of the Southern emperor, Godaigo (1339), who on his deathbed summoned all the imperial princes to his side, and laid upon them his earnest injunctions never to rest until the imperial power had been restored. He was succeeded by Prince Yoshinaga, who ascended the throne as Gomurakami. A series of reverses now overtook the imperialists. One after another their armies were defeated in the provinces, until Kitabatake Chikafusa alone remained unconquered in Hitachi. But he, too, was soon overpowered by the shōgun's forces. He effected his escape to Yoshino, and the emperor issued a summons to the warriors of Chiugoku and Nankai to reinforce the imperial army in Kiushū. The southern island was thus once more brought under the imperial sway, and this success encouraged Chikafusa at Yoshino, who now made one supreme effort. Assembling a force in Kyōto and its neighborhood, he attempted to reoccupy the city, and the suddenness of his effort seemed to him a temporary advantage. But Takauji dispatched large forces to attack the temporary palace at Yoshino, the defenders of which saw themselves utterly outnumbered. Kusunoki Masatsura, son of the great Masashige, had hitherto guarded the palace with stubborn bravery. But now he and his captains bade a final farewell to the sovereign, and, marching out to encounter the foe, fought their last battle at Shijōnawate, and fell fighting. After this victory, the shōgun's army burned the temporary palace at Yoshino, and the emperor escaped to Anau in Yamato.
