During the Civil War, the Jackson Purchase region of Kentucky, including Mayfield, was the area of strongest support for the Confederate cause. On May 29, 1861, a group of Southern sympathizers from Kentucky and Tennessee met at the Graves County Courthouse to discuss the possibility of aligning the Purchase with West Tennessee. Most records of the event were lost, possibly in an 1887 fire that destroyed the courthouse. In 1907, Fulton County judge Herbert Carr declared in a speech that the Mayfield Convention adopted a resolution for secession, and a historical marker in front of the courthouse also proclaims this as fact. However, the surviving records of the meeting, authored by a Union sympathizer, make no mention of this resolution, and historian Berry Craig opines that the convention believed the whole of Kentucky would eventually secede and make a resolution for the Purchase to break away unnecessary. Records do show that the convention adopted resolutions condemning President Lincoln for "waging a bloody and cruel war" against the South, urging Governor Beriah Magoffin to resist Union forces and praising him for refusing to answer Lincoln's call for soldiers, and condemning the provision of "Lincoln guns" to Union sympathizers in Kentucky. The convention also nominated Henry Burnett to represent Kentucky's First District in Congress. The Mayfield Convention was a precursor to the later Russellville Convention, which formed the provisional Confederate government of Kentucky.
