Shimazu Tadamune

Shimazu Tadamune (1251–1325) was the fourth head of the Shimazu clan and a Kamakura shogunate vassal. He fought beside his father Hisatsune in Kyushu during the Mongol invasions and succeeded as clan head in 1284.

He later served under the Kyushu deputy Hōjō Sanemasa. In 1317 he was made steward of estates in Hyūga and Hizen, which he parcelled out among his sons; these grants founded several Shimazu branch houses. He died in 1325 and was succeeded by Sadahisa.
