## History

In 1878, the district split off at the Tone River, forming Higashigunma and Nishigunma Districts. Since Higashigunma District areas was smaller, Higashigunma merged with Minamiseta District in 1896 to form Seta District. At the same time, Nishigunma merged with Kataoka District and renamed to Gunma District. In 1949, Kitagunma District was created out from Gunma District.
On October 1, 2006, the town of Haruna was merged into the expanded city of Takasaki. Therefore, Gunma District was dissolved as a result of this merger.
