Denmark
Denmark was divided into counties (amter) from 1662 to 2006. On 1 January 2007 the counties were replaced by five Regions. At the same time, the number of municipalities was slashed from 271 to 98.
The counties were first introduced in 1662, replacing the 49 fiefs (len) in Denmark–Norway with the same number of counties. This number does not include the subdivisions of the Duchy of Schleswig, which was only under partial Danish control. The number of counties in Denmark (excluding Norway) had dropped to c. 20 by 1793. Following the reunification of South Jutland with Denmark in 1920, four counties replaced the Prussian Kreise. Aabenraa and Sønderborg County merged in 1932 and Skanderborg and Aarhus were separated in 1942. From 1942 to 1970, the number stayed at 22. The number was further decreased by the 1970 Danish municipal reform, leaving 14 counties plus two cities unconnected to the county structure; Copenhagen and Frederiksberg.
In 2003, Bornholm County merged with the local four municipalities, forming the Bornholm Regional Municipality. The remaining 13 counties were abolished on 1 January 2007 where they were replaced by five new regions. In the same reform, the number of municipalities was slashed from 270 to 98 and all municipalities now belong to a region.
