Emperor Go-Yōzei
At the time, the battle was considered only an internal conflict between Toyotomi vassals. However, after Ieyasu was named "shōgun" in 1603 by Emperor Go-Yōzei, a position that had been left vacant since the fall of the Ashikaga shōgunate 27 years earlier, the battle was perceived as a more important event. In 1664, Hayashi Gahō, Tokugawa historian and rector of Yushima Seidō, summarised the consequences of the battle: "Evil-doers and bandits were vanquished and the entire realm submitted to Lord Ieyasu, praising the establishment of peace and extolling his martial virtue. That this glorious era that he founded may continue for ten thousands upon ten thousands of generations, coeval with heaven and earth."
