The parish of Hurum was historically located in Buskerud and Jarlsberg og Laurvig counties and it including land on both sides of the Drammensfjorden which was the dividing boundary between the two counties. The western side was called Strømmen (later changed to Strømm) and it was in Jarlsberg og Laurvig, which the eastern side of Hurum was in Buskerud. On 1 January 1838, the formannskapsdistrikt law went into effect and it made each parish into a civil municipality, but the new municipalities had to be in one county only. Because of this, Strømmen was established as its own municipality located wholly within Jarlsberg og Laurvig county. The town of Svelvik (population: 1,201) was established as a separate municipality on 1 January 1845 when it was separated from Strømm Municipality. This left Strømmen with 794 residents. During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, the town of Svelvik (population: 1,188) was merged with Strømm Municipality (population: 2,618) to form the new Svelvik Municipality.[6]
Name
The municipality (originally the parish) is named after the old Strømmen farm (Old Norse: Straumr) which is now where the town of Svelvik is located. The name is derived from the word straumr which means "stream" or "current". This is referring to the strong current in the narrow strait in the Drammensfjorden between Svelvik and Hurum.[7] Historically, the name of the municipality was spelled Strømmen. On 3 November 1917, a royal resolution changed the spelling of the name of the municipality to Strømm, removing the definite form ending -en.[8]
The municipal council(Herredsstyre) of Strømm was made up of 21 representatives that were elected to four year terms. The tables below show the historical composition of the council by political party.
