The story
It was established as a merger of the former municipalities of Farum in Frederiksborg County and Værløse in Copenhagen County on 1 January 2007 as a consequence of the Municipal Reform. The counties (Danish plural amtskommuner, singular amtskommune, literally county municipality) were abolished 1 January 2007 and replaced by regions, which are not municipalities.
