The Meitoku Reconciliation: How Yoshimitsu Ended a Fifty-Year Division

On the fifth day of the leap tenth month of 1392 (Meitoku 3), in Kyoto. Emperor Go-Kameyama of the Southern Court transferred the Three Sacred Treasures to Emperor Go-Komatsu of the Northern Court.

Fifty-six years after Emperor Go-Daigo had opened the Southern Court at Yoshino in 1336, the 'Nanboku-chō period' — in which two imperial lines stood in parallel in Japan — ended on this single day.

The Nanboku-chō began after Emperor Go-Daigo's Kenmu Restoration (1333-1336) was overthrown by Ashikaga Takauji, and Go-Daigo fled to Yoshino to open the Southern Court.

In Kyoto stood the Northern Court of Emperor Kōmyō, whom Takauji had raised up, and the two courts stood in parallel over the legitimacy of the Japanese imperial line.

This division greatly constrained the governing capacity of the Muromachi shogunate, and local warrior classes used both courts to conduct private strife.

Yoshimitsu advanced unification negotiations with the Southern Court from the 1380s.

The core condition was 'ryōtō tetsuritsu' — alternating imperial succession between the Southern and Northern lines.

This plan allowed the Southern Court to hand the Sacred Treasures to the Northern Court in a form that ostensibly 'recognized their legitimacy.

' The settlement of the fifth of the leap tenth month of 1392 was a diplomatic achievement of Yoshimitsu at thirty-five, at the peak of his power.

After Yoshimitsu's death, however, the shogunate did not keep the promise of alternating succession, and the imperial position was succeeded only by the Northern line (the imperial family that continues to the present).

Descendants of the Southern Court launched sporadic revolts as the 'Later Southern Court,' but after the Ōnin War they disappeared from the historical stage.

The Meitoku Reconciliation, contemporary scholarship evaluates, was in substance the absorption of the Southern Court by the Northern.

But the fact itself of politically resolving a division of more than fifty years does not move.
