Political crisis in the late Heian period of Japan

Timeline

1. 1103–1105Heian-kyō · KinkiShirakawa's cloistered rule continued; Emperor Horikawa reigned but real power was divided between the retired emperor and the sesshō-kampaku houses. Fujiwara no Tadazane served as regent, and court appointments and policy had to accommodate the In no Chō's wishes; courtiers repeatedly quarreled over estate interests and office distribution, and central decision-making was inefficient.
2. 1104–1106Kinai and the provinces · JapanTemple-shrine and courtier estates continued to expand, weakening provincial offices' control over land tax and labor. Local magnates and warriors were ordered to campaign or armed themselves to protect estates; the court could not centrally deploy forces, and security and finances were under double pressure.
3. 1105–1107Heian-kyō · KinkiWarrior clans such as the Minamoto and Taira were permitted to enter the capital for posts through subjugation and guard duties, gradually obtaining positions like provincial governors and kebiishi. The court relied on warriors to compensate for aristocratic military weakness, inadvertently raising their political weight and breaking the balance of Heian aristocratic politics.
