Chiba Sadatane

Chiba Sadatane, eleventh head of the Chiba clan, was the son of the tenth head Tanemune and took his name from the Hōjō regent Sadatoki. In 1312 he succeeded as shugo of Iga and Shimōsa. In 1333 he abandoned the Hōjō to join Nitta Yoshisada's attack on Kamakura, and from 1335 he fought his cousin Tanesada for the headship.

His heir fell in January 1336; that October Sadatane surrendered in Echizen, then defected to the Northern Court. He fought at Shijōnawate in 1348 and died in Kyoto in 1351.
