Strategically located in the Baltic Sea, Bornholm has been fought over for centuries.
It has usually been ruled by Denmark, but also by Lübeck and Sweden.
The island is situated between 54/59/11 and 55/17/30 northern latitude and 14/45 and 15/11 eastern longitude.
Directly west of Bornholm across the Baltic Sea mostly on the island of Sjælland are several municipalities of Region Sjælland: Stevns, Faxe, Næstved (the part that used to be the municipality of Fladså) and Vordingborg, including Møn, which is around 135 kilometres (84 miles) across the Baltic Sea.
From 1 January 2007 all counties were abolished, and Bornholm became part of Region Hovedstaden whose main responsibility is the health service.
The municipality still retains its name Bornholm Regional Municipality.
They will be reduced to 23 from 1 January 2018 (election November 2017).
The merger was approved in a law by the Folketing 19 March 2002, transferring the tasks of the abolished county and old municipalities to the new Bornholm Regional Municipality.
These islands, which do not belong to a municipality or region, are administered by the Danish Ministry of Defence. This makes the dialect difficult to understand for some Danish speakers.
However, Swedish speakers often consider Bornholmian to be easier to understand than standard Danish.
The island had 22 municipalities until March 1970, of which 6 were market towns and 16 parishes.
In addition to supervising parish municipalities, which was the responsibility of the counties in all of Denmark, the market town municipalities of Bornholm were supervised by Bornholm County as well and not by the Interior Ministry as was the case in the rest of Denmark.
It is the result of a merger of the five former (1 April 1970 until 2002) municipalities on the island (Allinge-Gudhjem, Hasle, Nexø, Rønne and Aakirkeby) and the former Bornholm County.
