What happened
In 794 Emperor Kammu moved the capital to Heiankyo (modern Kyoto), beginning the Heian period. Real political power soon shifted away from the throne to the Fujiwara clan, who repeatedly married their daughters to emperors and then governed as regent, sessho, while an emperor was a child, and as kampaku, chief advisor, once he came of age. Many Fujiwara statesmen served as regent across three or four emperors' reigns during a single career. The family's power peaked under Fujiwara no Michinaga, who married four daughters to four different emperors and ended up with an unprecedented four emperors as his own grandsons, prompting him to boast, "No waning in the glory of the full moon, this world is indeed my world!"
Why it matters
The Fujiwara regency created a durable pattern in Japanese politics: an emperor who reigns with religious and symbolic authority while a separate power holder actually rules, a template later shoguns would reuse for centuries. It also produced the wealthy, leisured court culture, centered on aristocratic women's own writing, that gave the world the Tale of Genji.
How we know
The Fujiwara regency and Michinaga's reported words survive through Heian-period court chronicles and diaries, cross-referenced with the imperial genealogical record showing the marriages themselves.
