Abe no Sadato

• Birth: 1019
• Death: 1062
• Significance: Samurai of the Abe clan in Mutsu province
• Japanese: 安倍貞任 (Abe no Sadatou)

Abe no Sadatô was the second son of Abe no Yoritoki, from whom he received ????. His older brother was Abe no Munetô. Because Mutsu province was so removed from the capital, the Abe clan were able to get away with not paying taxes, being expansionistic, and generally rebellious against the Imperial court.

The Imperial court finally sent Minamoto no Yoriyoshi and Minamoto no Yoshiie in 1051 to hold the Abe clan accountable. This began the Former Nine Years War, which lasted from 1051 to 1062.
