Norway was formed in 1792 immediately after the creation of Herkimer County. Norway was originally a very large town, and it was subsequently broken up, directly or indirectly, into about 36 new towns in several bordering counties. In Herkimer County, the towns of Fairfield (1796), Russia (1806), Ohio (1823), Wilmurt (now defunct), and Webb (1836) were made by dividing Norway. Part of Newport was taken from Norway in 1806. The creation of Oneida County, Lewis County, Clinton County, Hamilton County, and St. Lawrence County from Herkimer County accounts for the remaining towns derived from Norway.
