The area was first settled by farmers who located their farms along the wooded streams near present-day Nixa. The area became a crossroads, as it was a half-day ride with a team of horses from Springfield. Teamsters found it a convenient stopover site when hauling freight between Springfield and Arkansas. The village became known as Faughts. An early resident, Nicholas A. Inman, was a blacksmith from Tennessee, who set up a shop in 1852. When a post office was opened, a town meeting was held to decide on a name for the new community.
