Traditional history[change | change source]

Before he became the monarch, this prince's personal name (imina) was Ate (安殿).[4]

Heizei was the eldest son of the Emperor Kammu.[5]

He had three empresses and seven sons and daughters.[6]

Events of Heizei's life[change | change source]

Before he became the monarch, he was Crown Prince for over twenty years.

  • 785 (Enryaku 4, 11th month): Heizei was appointed Crown Prince at the age of 12.[6]
  • 9 April 806 (Daidō 1, 17th day of the 3rd month): In the 25th year of Kammu's reign, the emperor died; and the succession (senso) was received by his son. A short time later, Emperor Heizei is said to have acceded to the throne (sokui).[7] This was confirmed in ceremonies.[8]
  • 809 (Daidō 4, 1st month): After a reign of four years, Heizei fell ill and he feared that he would die. Heizei abdicated in favor of his younger brother who would be known as Emperor Saga. After abdicating, Heizei moved to Nara; and he was known as the "Emperor of Nara" (Nara no Mikado).[9]
  • 18 May 809 (Daidō 4, 1st day of the 4th month): Emperor Saga was enthroned at age 24.[9]
  • 5 August 824 (Tenchō 1, 7th day of the 7th month): Heizei died at 14 years after his abdication.[11]

According to the Imperial Household Agency, the mausoleum (misasagi) of Heizei is in Nara. The emperor is traditionally venerated at a memorial Shinto shrine at this location.[1] The site can be visited by the public.[12]

The years of Heizei's reign are identified by only one era name (nengō).[13]
