The area of present-day Kitakami was part of ancient
Mutsu Province, and has been settled since at least the
Jōmon period by the
Emishi people. The area was a stronghold for the Emishi chieftain
Aterui until his death at the hands of
Sakanoue Tamuramaro. During the later portion of the
Heian period, the area was ruled by the
Abe clan, and became a battleground during the
Former Nine Years War. The Abe were followed by the
Northern Fujiwara clan. During the
Sengoku period, the area came under the control of the
Nanbu clan. The area was part of
Morioka Domain during the
Edo period, under the
Tokugawa shogunate, with the exception of two villages on its southeastern border, which were under
Sendai Domain. The town of Kurosawajiri was established by the
Meiji period creation of the modern municipalities system on April 1, 1891. The modern city of Kitakami was founded on April 1, 1954, by the merger of the town of Kurosawajiri, with the villages of Iitoyo, Futako, Saraki, Oniyanai, Aisari and Fukuoka. On April 1, 1991 Kitakami absorbed the neighboring village of Ezuriko and town of Waga (both from
Waga District). ==Government==
