Rugby was founded in 1886 at a junction on the Great Northern Railway, where a branch line to Bottineau met the main line. The railroad promoters initially platted the town as Rugby Junction, getting the name Rugby from the town of Rugby in Warwickshire, England.[6] It was one of several sites along the Great Northern's transcontinental route between Devils Lake and Minot that were named after places in England (the others were Berwick, Leeds, Knox, Norwich, Penn, Surrey, Churches Ferry, Tunbridge, and York). When the community became a city, the Junction was dropped from the name.

Larimore had its start in the year 1881 by the building of the railroad through that territory. It is named for N. G. Larimore, who owned a large farm in the area
