History
Fort Branch takes its name from a frontier military outpost that was established in the area during the early nineteenth century, reflecting the town's origins during Indiana's formative settlement period. The surrounding Gibson County region was developed largely through agricultural settlement following Indiana's statehood in 1816, and the town grew as a local market center serving nearby farming families. Over the decades, Fort Branch developed its own municipal identity, incorporating as a town and eventually growing into the small city it remains today.
