History
Amidon was founded in 1910 at the anticipated terminus of a Milwaukee Road branch line that diverged from the railroad's Pacific Extension in McLaughlin, South Dakota. The line was ultimately never built farther west of New England, North Dakota, making Amidon one of the few surviving North Dakota cities never to have been served by a rail line. The original county courthouse was built in 1915. It was also the last county seat in the state to get electricity when Slope Electric Cooperative extended their distribution lines into Amidon in 1950.
Amidon is named after Charles F. Amidon, a federal judge for the United States District Court for the District of North Dakota.
