Nanboku-chō period
In 1392, the Southern court stopped fighting; and the Northern Court seemed to have won the long struggle. However, the claims of the Kyoto pretenders were undermined by scholars and historians.  The so-called "emperors" in Kyoto did not have of the essential Imperial regalia until after 1392.  The succession (senso) was not passed to them from Emperor Go-Daigo.  The pretenders were not confirmed with valid ceremonies (sokui).
