Although the treaty was brought to the court in Kyoto by roju Masayoshi HOTTA, it was not signed due to a struggle of succession concerning the heir of the 13th shogun Iesada TOKUGAWA between the Nanki group (Yoshitomi loyalists from the Kishu-Tokugawa family) and the Hitotsubashi group (Yoshinobu loyalists from the Hitotsubashi-Tokugawa family). 老中堀田正睦はこれを京都の朝廷に上奏したが勅許を得られず、13代将軍徳川家定の将軍継嗣問題とも関係して南紀派、一橋派の抗争となる。 |
