Template:Distinguish Template:Distinguish Template:Use mdy dates

Template:Nihongo, also known as Heijō-tennō, was the 51st emperor of Japan,<ref name="kunaichō">Emperor Heizei, Yamamomo Imperial Mausoleum, Imperial Household Agency</ref> according to the traditional order of succession.<ref>Ponsonby-Fane, Richard.

Traditional narrativeEdit

Heizei was the eldest son of the Emperor Kanmu and empress Fujiwara no Otomuro.<ref>Varley, p. 151; Brown, p. 279.</ref> Heizei had three empresses and seven sons and daughters.<ref name="b279">Brown, p. 279.</ref>

Heizei is traditionally venerated at his tomb; the Imperial Household Agency designates Template:Nihongo3, in Nara, as the location of Heizei's mausoleum.<ref name="kunaichō" /> The site is publicly accessible.<ref>Nara City Sightseeing Information Center (Narashikanko): Heizei's misasagi, map Template:Webarchive</ref> Although one of the largest kofun monuments in Japan, archaeological investigations in 1962–1963 indicate that it was constructed in the early 5th century, and that portions of it were destroyed during the construction of Heijō-kyō, calling into question the designation by the Imperial Household Agency.

Events of Heizei's lifeEdit

Before he ascended to the throne, his liaison with Fujiwara no Kusuko, the mother of his one consort, caused a scandal. Because of this scandal his father considered depriving him of the rank of crown prince.

785: (Template:Nihongo foot): Heizei was appointed Crown Prince at the age of 12.<ref>Brown and Ishida, p. 279</ref>
April 9, 806 <ref>Julian dates derived from NengoCalc</ref> (Template:Nihongo foot): In the 25th year of Emperor Kanmu's reign, he died; and despite an ensuing dispute over who should follow him as sovereign, contemporary scholars then construed that the succession (senso) was received by his son. Shortly thereafter, Emperor Heizei is said to have acceded to the throne (sokui).<ref>Titsingh, p. 95; Brown and Ishida, p. 279; Varley, p. 44; a distinct act of senso is unrecognized prior to Emperor Tenji; and all sovereigns except Jitō, Yōzei, Go-Toba, and Fushimi have senso and sokui in the same year until the reign of Emperor Go-Murakami.</ref>

His title Heizei was derived from the official name of the capital in Nara, Heizei Kyō.

During Heizei's reign, the bodyguards were reorganized; the existing Imperial Bodyguards became the Left Imperial Bodyguards, while the Middle Bodyguards became the Right Imperial Bodyguards.<ref name="b280">Brown and Ishida, p. 280</ref> Both sides were given a new Senior Commander; at this time Heizei appointed Sakanoue no Tamuramaro (758–811) as Senior Commander of the Imperial Bodyguards of the Right.<ref name="b280"/> Under Emperor Kanmu, Tamuramaro had been appointed as shōgun of a military expedition against the Emishi.<ref>Brown and Ishida, p. 279; Varley, p. 272; Titsingh, p. 99.</ref>

809 (Template:Nihongo foot): After a reign of four years, Heizei fell ill; and fearing that he would not survive, Heizei abdicated in favor of his younger brother, who would later come to be known as Emperor Saga.<ref name = "b280"/> After abdicating, Heizei moved to Nara and was henceforth known as Nara no Mikado, the "Emperor of Nara".<ref name = "b280"/>
May 18, 809 (Template:Nihongo foot): Emperor Saga was enthroned at age 24.<ref name = "b280"/>
810 (Kōnin 1): In Heizei's name, the former emperor's ambitious third wife, Template:Nihongo, and her brother Nakanari organized an attempted rebellion, but their forces were defeated. Kusuko died in poison and her brother was executed. Heizei took the tonsure and became a Buddhist monk.<ref name="ponsonby318">Ponsonby-Fane, p. 318. Brown and Ishida, pp. 281</ref>
August 5, 824 (Template:Nihongo foot): Heizei died at age 51, 14 years after he had abdicated due to illness.<ref>Brown and Ishida, p. 280; Varley, p. 151.</ref>

Era of Heizei's reignEdit

The years of Heizei's reign are encompassed within one era name (nengō).<ref>Titsingh, p. 96.</ref>

Daidō (806–810)

KugyōEdit

Template:Nihongo is a collective term for the very few most powerful men attached to the court of the Emperor of Japan in pre-Meiji eras.<ref>Furugosho: Kugyō of Heizi-tennō</ref>

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 Heizei's reign, this apex of the Daijō-kan included:

Sadaijin (not appointed)
Udaijin, Miwa-no-Oh or Miwa-no-Ohkimi (神王), 798–806.<ref name="b279"/>
Udaijin, Fujiwara no Uchimaro (藤原内麿), 806–812.<ref name="b280"/>
Naidaijin
Dainagon, Fujiwara no Otomo (藤原雄友), 806–807

When the daughter of a chūnagon became the favored consort of the Crown Prince Ate (later known as Heizei-tennō), her father's power and position in court was affected. Kanmu disapproved of Template:Nihongo, former wife of Fujiwara no Tadanushi; and Kanmu had her removed from his son's household. After Kanmu died, Heizei restored this one-time favorite as part of his household; and this distinction had consequences.<ref name="ponsonby318"/>

Chūnagon, Fujiwara no Tadanushi<ref name="ponsonby318"/>
