Emperor Kōgon
A puppet emperor installed by samurai warlords, his brief reign ignited a 60-year schism that split the Japanese imperial line in two.
1313–1364 (age 51)·Japanese Northern Emperor from 1331 to 1333·Birthday: August 1
Biography
Emperor Kōgon's accession was not a celebration but a symptom of collapse. In 1331, as the Kamakura shogunate sought to crush the rebellious Emperor Go-Daigo, they plucked Prince Kazuhito from the imperial family and placed him on the throne as Kōgon. His three-year reign was entirely orchestrated by military rulers, a hollow performance of legitimacy. When Go-Daigo briefly restored imperial power in the Kenmu Restoration, Kōgon was deposed. But the schism proved permanent. After samurai forces drove Go-Daigo south, they reinstalled Kōgon in 1336, creating the Northern Court in Kyoto, while Go-Daigo established a rival Southern Court in Yoshino. Thus began the turbulent Nanboku-chō period. Kōgon, though a political pawn, became the progenitor of this Northern line. He eventually abdicated and entered monastic life, a former emperor who had witnessed the throne become a prize for warlords.
