Settled as early as 1796, Springboro was founded in 1815 by Jonathan Wright, as "Springborough." Jonathan Wright's father Joel was a surveyor who plotted Columbus and Dayton, Ohio and Louisville, Kentucky. Springboro was predominantly Quaker during its early years.
By the 1830s, two mills and a woolen factory in Springboro had been built up on the abundant springs for which the town was named.
As a stop on the Underground Railroad, Springboro played a significant role by providing hiding places for escaping slaves. On October 17, 1999, Springboro was the first city to erect an Ohio Underground Railroad Historic Marker. The dedication was part of the 4th Annual Ohio Underground Railroad Summit.
Today Springboro is one of the most important exurbs in the Cincinnati-Dayton metro area due to its stronghold on the growth between the two major cities. The mayor of Springboro is John H. Agenbroad, who was reelected in 2011.
