Jinshin War
The Jinshin War (壬申の乱, jinshin no ran) was the war of succession in Japan during the Asuka period of the Yamato state. It broke out in 672 following the death of Emperor Tenji. The name refers to the jinshin (Ch. renshen 壬申) or ninth year of the sexagenery cycle, corresponding to the Gregorian year 672. Tenji had originally designated his brother, Prince Ōama, as his successor, but later changed his mind in favor of his son, Prince Ōtomo.
