## History

Shimokita District was part of ancient Kita County (北郡, Kita-gun), established by the Northern Fujiwara. During the Edo period, the area was part of the Morioka han feudal domain of the Nanbu clan, with a daikansho located in Tanabu (now part of the city of Mutsu.
The Nanbu clan sided with the Ōuetsu Reppan Dōmei during the Boshin War of the Meiji Restoration and were punished by the new Meiji government by loss of their northern territories. In November 1869, Kita-gun and neighboring Sannohe District became part of the newly created Tonami Domain (斗南藩, Tonami-han), a 30,000 koku holding created to resettle the dispossessed Matsudaira clan from Aizu-Wakamatsu. In July 1871, with the abolition of the han system, Tonami Domain became Tonami Prefecture, and was merged into the newly created Aomori Prefecture in September 1871.
During the early Meiji period administrative reorganization of Japan on July 22, 1878, Shimokita and Kamikita were divided from former Kita County, and Shimokita was divided into 33 villages. In the cadastral reform of April 1, 1889, the number of villages was reduced through consolidations and mergers to nine.
