The settlement in the area now known as Davenport was established in 1838 when the U.S. military set up Fort Davenport during the Second Seminole War, about 12 miles north of the present site of Davenport. The fort was one of a number built at 20 mile intervals along a trail from Fort Brooke to Fort Mellon. The fort only lasted a few years. The fort was named for Colonel William Davenport, who served as the local U.S. commander in the war. There is no known documentary evidence to support an alternative claim that the city was named for a railroad conductor.
