First Horizon Bank, historically known for many decades as First Tennessee Bank, was founded in Memphis in 1864 during the height of the American Civil War. Established to provide essential commercial banking services, currency stabilization, and economic reconstruction support in a deeply divided region, the institution demonstrated extraordinary resilience and steady growth. Over a century and a half of continuous operation, it expanded its branch network across the state and the broader American South, evolving into a premier regional financial services company while retaining its historical charter and headquarters in Tennessee.
