Origins & Early Life

Prince Moriyoshi (護良親王, Moriyoshi Shinnō) (1308 – August 12, 1335) was a Japanese prince, military leader and monk. He was the son of Emperor Go-Daigo and his consort Minamoto no Chikako. Moriyoshi was named by his father as the head abbot of the Enryaku-ji temple on Mount Hiei. Go-Daigo attempted to seize power in 1331 during the Genkō War. Prince Moriyoshi joined forces with Kusunoki Masashige.

Career & Major Achievements

Moriyoshi tenaciously defended Mount Yoshino. Masashige's heroics defending Chihaya, together with Moriyoshi's efforts to rally troops, brought a large number of warriors to the loyalist cause. By 1333, the rival warlords Ashikaga Takauji and Nitta Yoshisada had both joined the cause; Yoshisada would lay siege to Kamakura in the same year. When the city finally fell, Regent Hōjō Takatoki fled to Tōshō temple, where he and his entire family committed suicide. This marked the end of Hōjō power.

Enduring Legacy & Impact

Restored to the throne, Go-Daigo started the Kenmu Restoration. After refusing to appoint Ashikaga Takauji to the post of sei-i taishōgun, Go-Daigo gave it to Prince Morinaga instead. Go-Daigo made the double mistake of giving the title to his sons Moriyoshi and Norinaga, two civilians, thus alienating Takauji and the warrior class, who felt he, as a military man and a descendant of the Minamoto clan, should have been shōgun instead. Takauji seized Moriyoshi in Yoshino "on imperial warrant", after rumors attributed to Go-Daigo's consort Renshi, that he was preparing an attack. Moriyoshi was then sent to Takauji's brother Ashikaga Tadayoshi in Kamakura.
