The municipality of Stjørdalen was established on 1 January 1838 (see formannskapsdistrikt). In 1850, the municipality of Stjørdalen was divided into Øvre Stjørdal (population: 5,100) and Nedre Stjørdal (population: 6,543).[5]
Name
The municipality (originally the parish) is named after the Stjørdalen valley (Old Norse: Stjórardalr). The first element is the genitive case of the local river name Stjór (now called the Stjørdalselva river). The meaning of the river name is unknown. The last element is dalr which means "valley" or "dale".[6]
