The community was founded in 1792. Located near a route from Louisville to Frankfort, Kentucky, Shelbyville grew to a population of 262 by 1800. For much of its early history, most residents were employed directly in support of the surrounding agriculture-based economy.
On August 24, 1864 a group of Confederate soldiers attacked the courthouse, attempting to seize a cache of weapons there. They were fought off by locals, killing three of the soldiers in the process. The town later supported Union efforts under Gen. John Palmer to track down Confederate guerrillas in surrounding counties.
