the family. Because of the sudden death of Emperor Shijō at the age of 10, the question of succession arose. Because the expectations of the court nobility and the Bakufu conflicted, the issue was bitterly contested. Kujō Michiie and the court nobility supported Prince Tadanari (忠成王), a son of Retired Emperor Juntoku, but the shikken Hōjō Yasutoki was opposed to the sons of Juntoku because of his involvement in the Jōkyū War. Michiie instead supported Tsuchimikado's son Prince Kunihito as a neutral figure for Emperor. During these negotiations, there was a vacancy on the throne of 11 days. 11 February 1242 (Ninji 3, 10th day of the 1st month): In the 10th year of Shijō-tennō 's reign (四条天皇10年), the emperor died suddenly; and despite a dispute over who should follow him as sovereign, contemporary scholars then construed that the succession (senso) was received by the second son of former Emperor Tsuchimikado. 19 April 1242 (Ninji 3, 18th day of the 3rd month): Emperor Go-Saga is said to have acceded to the throne (sokui). In 1242, Prince Kunihito became emperor. In 1246 he abdicated to his son, Emperor Go-Fukakusa, beginning his reign as cloistered emperor. In 1259, he compelled Emperor Go-Fukakusa to abdicate to his younger brother, Emperor Kameyama. Imperial Prince Munetaka became shōgun instead of the Hōjō regents. Henceforth, the shōguns of the Kamakura Bakufu came from the imperial house. Still, the Hōjō regents increased their control of the shogunate, setting up the system of rule by regents. The descendants of his two sons contested the throne between them, forming into two lines, the Jimyōin-tō (Go-Fukakusa's descendants) and the Daikakuji-tō (Kameyama's descendants). Their lines would eventually lead to the split between the Northern and Southern Courts. In 1272, Go-Saga died. Go-Saga's final resting place is designated as an Imperial mausoleum (misasagi) at Saga no minami no Misasagi at Tenryū-ji in Kyoto. Kugyō is a collective term for the very few most powerful men attached to the court of the Emperor of Japan in pre-Meiji eras. Even during those years in which the court's actual influence outside the palace walls was minimal, the hierarchic organization persisted. In general, this elite group included only three to four men at a time. These were hereditary courtiers whose experience and background would have brought them to the pinnacle of a life's career. During Go-Saga's reign, this apex of the Daijō-kan included: Kampaku, Konoe Kanetsune,
