Fujiwara No Fuhito

Fujiwara no Fuhito (藤原 不比等: 659 – September 13, 720) was a powerful member of the imperial court of Japan during the Asuka and Nara periods. Second son of Fujiwara no Kamatari (or, according to one theory, of Emperor Tenji), he had sons by two women, and those sons were the founders of the four principal lineages of the Fujiwara clan: the South, North, Ceremonial, and Capital lineages. Also, he had four daughters by two other women. three by Kamohime, one by Tachibana no Michiyo. One daughter by Kamohime became Emperor Mommu's wife Miyako, who in turn gave birth to Emperor Shōmu. The daughter by Michiyo became the empress of his grandson Shōmu, Empress Kōmyō.

During the reign of Emperor Mommu, the government ordered that only the descendants of Fuhito could bear the Fujiwara surname and could be appointed in the Office of Dajokan, the center of administratives.
