From Wikipedia, the free encyclopedia

Nin'an (仁安 ?), also known as Ninnan, was a Japanese era name (年号, nengō, ?, lit. "year name") after Eiman and before Kaō. This period spanned the years from 1166 through 1169. The reigning emperors were Rokujō-tennō (六条天皇 ?) and Takakura-tennō (高倉天皇 ?).[1]


Change of era

  • February 3, 1166 Nin'an gannen (仁安元年 ?): The new era name was created to mark an event or series of events. The previous era ended and a new one commenced in Eiman 2, on the 27th day of the 8th month of 1166.[2]

Events of the Nin'an era

  • 1168 (Nin'an 3, 2nd month ): Rokujō was deposed at age 5, and he received the title Daijō-daijin tennō.[3]
  • March 30, 1168 (Nin'an 3, 19th day of the 2nd month): In the 3rd year of Rokujō-tennō 's reign (六条天皇3年), the emperor was deposed by his grandfather, and the succession (‘‘senso’’) was received by his cousin, the third son of the retired-Emperor Go-Shirakawa. Sometime thereafter, Emperor Takakura is said to have acceded to the throne (‘‘sokui’’), and he is proclaimed emperor.[4]
  • April 29, 1168 (Nin'an 3, 20th day of the 3rd month): Takakura succeeds Rokujo on the Chrysanthemum Throne.[5]
