Since the former Emperor Go-Komyo's adopted son, Prince Satohito (later called Emperor Reigen) was too young to succeed to the Imperial Throne, Prince Nagahito was soon enthroned as Emperor Gosai for the meantime; the Emperor ordered his Prince Arisugawa no miya Yukihito to take over Takamatsu no miya so that his original name as a court noble was changed to Arisugawa no miya (the name came from Prince Yoshihito's temporary palace in Arisugawa, Kyoto).
やがて良仁親王が後西天皇として即位することになるが、これは先代後光明天皇の養子・識仁親王（後の霊元天皇）が幼少であったための中継ぎであり、後西天皇は自分の皇子・有栖川宮幸仁親王に高松宮を継がせて、宮号を有栖川宮（幸仁親王の別荘所在地である京都・有栖川に由来）に改めた。
