The community of Bloomington was settled in June 1854 but was not called as such until April 1855 when Harrison Burson applied to the U.S. Government for a post office. Within eight months of the area being settled some 530 settlers were in the area that would become Bloomington-Clinton. The people of Bloomington were greatly anti-slavery and helped slaves escape through the Underground Railroad. In early 1857, the north half of Bloomington was moved to a new location and the south portion of the community was renamed Winchester.
