Human occupation of Jackson County began about 11,500 years ago. Extensive documentation of the area’s indigenous peoples is ongoing. Exploration from the European explorers began with the Joliet-Marquette exploration along the Mississippi River. It was not until the 18th and 19th century when pioneer farmers began to settle in the area’s inexpensive land along the Mississippi River and in the forested Shawnee hills with its one-hundred-foot trees.

As early as 1810 William Boone and his indentured servant Peter mined coal from the banks along Big Muddy River. This was Illinois’ first coal mine. By 1813, Conrad Will, namesake of Will County, conducted a large salt extraction operation using slave labor on the banks of the Big Muddy River, south of today’s Murphysboro. As this was in the “free” Northwest Territory, Will had to have a legal exemption to own slaves. Jackson County, Illinois’ ninth county to be organized, was organized in 1816, having been carved out of Randolph County, Illinois on the north and Johnson County, Illinois on the South. It was named for Andrew Jackson, who had just defeated the British Army at the Battle of New Orleans. Brownsville, located near Will’s salt works, was established as the county seat. When the courthouse burned in 1843, the county voted to move the county seat to a more central location. Murphysboro, located on land owned by Dr. John and Elizabeth (Jenkins) Logan, became the second county seat in September 1843. It was named after William C. Murphy, one of the three Commissioners appointed to select the site.

Civil War Major General John A. Logan, Dr. John and Elizabeth Logan’s son, was born in what is now Murphysboro on February 9, 1826. During the Civil War he moved to Carbondale, about 10 miles (16 km) east of his birthplace. He moved to Chicago in 1871. During his residence in Carbondale, he took part in a Memorial Day observation at that city’s Woodlawn Cemetery. In 1868, Logan, as Commander of the Grand Army of the Republic, issued General Order No. 11 which established Memorial Day as a national holiday.

On 18 March 1925, the great Tri-State Tornado ripped through Jackson County, leaving devastation in its path. The villages of Gorham and De Soto and the city of Murphysboro were hit especially hard.

The county courthouse is in downtown Murphysboro. The current reinforced concrete courthouse, completed in 1928, replaced earlier brick structures.
