Marianna, the seat of Jackson County, was founded in 1828 on the Chipola River by Scottish entrepreneur Scott Beveridge, also spelled Beverege, who named it for his daughters Mary and Anna. The next year it became the county seat, drawing businesses away from the former seat, Webbville, which faded away. Planters from North Carolina moved to Jackson County to develop plantations on its fertile soil, relying on the labor of enslaved African Americans brought from the Upper South.
More about Marianna
Marianna was home to Florida's Civil War governor, John Milton, a major planter who owned the Sylvania Plantation. On September 27, 1864, a Federal force of about 700 cavalry from Pensacola under General Alexander Asboth arrived to forage and enlist Black recruits. A few hundred Confederate home guards, many of them boys, older men and wounded soldiers, barricaded the streets and held off the first assault but surrendered when they were outflanked. Confederate casualties were 26 and Federal about 55; the town was spared, but St. Luke's Episcopal Church, in the middle of the fighting, was burned. On April 1, 1865, as the Confederacy collapsed, Governor Milton was found dead of a gunshot wound at Sylvania; the New York Times called it suicide, while a local paper reported a hunting accident. He is buried in St. Luke's churchyard.
During Reconstruction, Ku Klux Klan violence flared in Marianna and the surrounding county, much of it aimed at Black freedmen who were gaining ownership of farmland. Today Marianna is home to Chipola College and calls itself "The City of Southern Charm."
