Blackfoot is the principal city of the Blackfoot, ID Micropolitan Statistical Area, which includes Bingham County.
The first general store was built in 1874 by Fredrick S. Stevens and Major Danilson after learning that a railroad was to be built in the area. They were hoping that a station would be built there because it was just outside the Fort Hall Indian Reservation, which speculation paid off four years later. October 10, 1878 a post office was established with Theo T. Danilson as Postmaster. November 10, 1878 track was laid through town, with the track running right up behind the Stevens Store to take advantage of the store's loading platform (which was originally used to unload freight wagons). The name of the town was changed to Blackfoot March 20, 1879.
On January 13, 1885 Bingham County was established with Blackfoot as its county seat. Originally the county seat was to be Eagle Rock (now called Idaho Falls). However, the night before its final passage men from Blackfoot bribed a clerk to erase Eagle Rock and write in Blackfoot. The measure went through without opposition and was signed by the governor.
Blackfoot was incorporated as a town in 1907
