Minamoto no Yoshinaka, also known as Kiso Yoshinaka, was a Japanese samurai lord mentioned in the epic poem The Tale of the Heike.

The Heiji rebellion was a short civil war between rival subjects of the cloistered Emperor Go-Shirakawa of Japan in 1160 fought in order to resolve a dispute about political power. It was preceded by the Hōgen Rebellion in 1156. Heiji no ran is seen as a direct outcome of the earlier armed dispute; but unlike Hōgen no ran, which was a dispute between Emperors in which members of the same clan fought on different sides, this was rather a struggle for power between two rival samurai clans. It is also seen as a precursor of a broader civil war.
