In 1864, Fort Blakeley, which was a Confederate earthworks and log fortification was established in Blakeley, which was at the one the county seat of Baldwin County, Alabama. On April 9, 1865, Fort Blakeley was attacked and captured by Union forces in the Battle of Fort Blakeley, which was the end of the Mobile Campaign and the last major battle of the U.S. Civil War.
In 1813, Blakeley, Alabama was founded by Josiah Blakeley, “an entrepreneur and adventurer from Connecticut” who moved to Mobile in 1806. He purchased 7,000 acres of land in the northeastern portion of Mobile Bay. In 1813 he hired a surveyor to lay out the town of Blakeley and sold the first 10 lots. Eventually, the town of Blakeley would become the county seat of Baldwin County.
Baldwin County was established on December 21, 1809, ten years before Alabama became a state. Previously, the county had been a part of the Mississippi Territory until 1817, when the area was included in the separate Alabama Territory.
