Irwin County is a county located in the U.S. state of Georgia. As of the 2010 census, the population was 9,538. The county seat is Ocilla. The county was created on December 15, 1818. It was named for Governor Jared Irwin.
In the last years of the American Civil War, Irwin County gained the nickname of the Republic of Irwin due to the Unionism of many of its residents. The location where Jefferson Davis was captured  is located in Irwin County near Irwinville.
The territories of Appling, Irwin, and Early counties were land newly ceded in 1814 and 1818. These counties were created by a legislative act on December 15, 1818. All or portions of Irwin's five adjacent counties were created from Irwin county along with all of Cook, Colquitt, Lanier, Lowndes, counties and portions of Atkinson, Brooks, Echols, Wilcox, and Worth counties. Irwin was divided into 16 districts of 20 miles and 10 chains square with lots of 70 chains square containing 490 acres according to the Act of 1818. In 1820 each lot was priced at $18, but by 1831 the price was down to $5 per lot.
At the time of the 1820 census, when it included much of central south Georgia, Irwin County had a white population of 372 whites and 39 slaves. In 1825, Lowndes County was formed out of the 8th, 9th, 10th, 11th, 12th, 15th, and 16th land districts in what was then the southern half of the county. In 1830, the county had 1,066 whites, 109 slaves, and 5 free people of color. In 1840, Irwin County had 1,772 whites and 266 slaves. In 1850. Irwin County had 2,874 whites, 459 slaves, and 1 free person of color. In 1853, Worth County was formed out of part of Irwin County. In 1854, Coffee County was also formed from Irwin. In 1860, Irwin County had 1,453 whites and 246 slaves. It was one of a few counties in Georgia outside of mountainous northern Georgia with slaves accounting for a small percentage of its population.
During the American Civil War, like the United States in general, Irwin County was also ideologically divided. The county was one of the poorest at the time in Georgia. It was home to a number of Southern Unionists who opposed secession and the Confederacy. The county also provided several regiments to the Confederate Army including:
In May 1863, several companies of Duncan Lamont Clinch Jr's Fourth Georgia Cavalry were charged with searching Irwin County for deserters. They spent a month searching the county, but were only able to find twenty-two deserters on May 22, the day they arrived. The deserters were sent to Savannah for enlistment or prosecution.
A prominent Unionist in the county was Willis Jackson Bone. He lived west of Irwinville, near the Alapaha River. He was a miller and operated a steam-powered mill on what was then Bones Pond and presently Crystal Lake. Because he was a gristmill operator, Bone was exempt from conscription. During the Civil War, he helped a number of escaped slaves, Confederate deserters, and escaped Union prisoners hide in the swamps along the river. In February 1865, Bone and a large assembly of others gathered in Irwinville. Those assembled declared Irwin County part of the Union again. A lieutenant of the local militia protested the action, but was knocked down with a musket by Bone. Three cheers for Abraham Lincoln followed. The assembly then took after the lieutenant and the enrolling officer Gideon Brown. They and other Confederate sympathizers were chased out of town and threatened with death if they should return. Willis Jackson Bone was hanged near his pond in late April 1865 after he killed a local justice of the peace named Jack Walker while Bone was bringing food to an escaped slave named Toney. Walker had tried to take Toney into custody.
A few months later, Irwinville became the site of the capture of Confederate President Jefferson Davis. Davis was on his way from the capital of the Confederacy at Richmond, Virginia to board a ship with his family and flee to safety in England, Davis stopped at a hotel in Irwinville owned by Doctor G.E. White on the evening of May 9, 1865. There he conversed and socialized with the locals and no one had suspected that they were in the presence of a man of such esteem. Davis and his family moved to an encampment beside a nearby creek bed only a couple of miles from the hotel after they were done talking with the citizens of Irwinville and sometime in the early morning of May 10, the encampment was alarmed by the sound of gunfire. Davis tried to escape towards the creek wearing an overcoat and his wife had tied her scarf around his shoulders, but members of the First Wisconsin and Fourth Michigan Cavalry Regiments captured him. He was taken to Fortress Monroe, Virginia and held for two years. The location is now the Jefferson Davis Memorial Historic Site.
