Rise of the Taira (after the Heiji Rebellion)

Timeline

1. 1160Kyoto · KinkiAfter the Heiji Rebellion, Taira no Kiyomori was appointed grand chancellor for his merit in suppressing the rebellion, becoming the first person of warrior status to hold the post. This broke the court nobles' monopoly on the highest office and marked warrior power's formal entry into the top tier of court power.
2. 1160–1170Japan · JapanKiyomori's sons Taira no Shigemori, Taira no Munemori, and others successively took key posts, with the Taira clan occupying nearly half the seats of the court nobility. The Taira held vast estates in the western provinces and controlled Japan–Song trade, their economic and military power expanding in tandem, creating a situation where "the Taira clan was the court."
3. 1160Eastern provinces · Eastern provincesAfter Minamoto no Yoshitomo's defeat, his son Minamoto no Yoritomo was exiled to Izu in the east, and Minamoto no Yoshitsune, Minamoto no Yoshii, and others scattered in various directions. The Minamoto's power at court nearly collapsed, but Yoritomo gradually accumulated strength in the eastern provinces, laying the groundwork for the Genpei War twenty years later.
