Death of Fujiwara no Michinaga and political upheaval

Timeline

1. 1002Heian-kyo · KinkiKampaku Fujiwara no Michitaka died in the twelfth month of Choho 4, at only thirty-seven years old. Since serving as Kampaku from the Chotoku era, Michitaka had been extremely powerful, with his sons holding key offices, forming the prominent Michitaka house political bloc.
2. 1002Heian-kyo · KinkiAfter Michitaka's death, the Kampaku post was temporarily held by his brother Fujiwara no Michikane, but Michitaka's sons were young and their power unestablished, creating a power vacuum in court governance. Fujiwara no Michinaga (Michitaka's brother) and the Michitaka line began a covert struggle for power.
3. 1002–1003Heian-kyo · KinkiThe Michitaka house's power declined with the loss of its leader, while Michitaka's brother Fujiwara no Michinaga gradually expanded his influence, laying the foundation for his daughter Fujiwara no Shoshi's later entry into the palace and the Michinaga line's dominance of court politics, turning the mid-Heian sekkan political order.
