Medieval ruin In
Old Norse the island was known as
Burgundaholmr, and in
ancient Danish especially the island's name was
Borghand or
Borghund; these names were related to Old Norse
borg 'height' and
bjarg/berg 'mountain, rock' because it is an island that rises high from the sea. Other names known for the island include
Burgendaland (9th century),
Hulmo /
Holmus (
Gesta Hammaburgensis ecclesiae pontificum),
Burgundehulm (1145), and
Borghandæholm (14th century). The Old English translation of Orosius uses the form
Burgenda land. There are scholars who believe that the
Burgundians are named after Bornholm. The Burgundians were a
Germanic people who were settled in the
Rhone region by the Romans, and who the region of
Burgundy in
France is named after.
Modern Bornholm was pawned to
Lübeck by
Frederick I of Denmark for 50 years starting in 1525, in payment for its support in his acquisition of the Danish throne. Its first militia,
Bornholms Milits, was formed in 1624. Swedish forces conquered the island during the
Torstenson War in 1645, but returned the island to Denmark in the
following peace settlement. After the war in 1658, Denmark ceded the island to Sweden under the
Treaty of Roskilde along with the rest of the
Skåneland,
Bohuslän and
Trøndelag, and it was occupied by Swedish forces.
A revolt broke out the same year, culminating in Villum Clausen's shooting of the Swedish commander
Johan Printzensköld on 8 December 1658. After the revolt, the inhabitants handed back their island to the Danish kings. Bornholm attracted many famous artists at the beginning of the 20th century, forming a group now known as the
Bornholm school of painters. In addition to
Oluf Høst, they include
Karl Isaksson (1878–1922) from Sweden, and the Danes
Edvard Weie (1879–1943),
Olaf Rude (1886–1957),
Niels Lergaard (1893–1982), and
Kræsten Iversen (1886–1955).
World War II In the early morning of 9 April 1940, German forces
occupied Denmark and began the invasion of Norway (
Operation Weserübung). On 22 August 1942 a
V-1 flying bomb crashed on Bornholm during a test – the warhead was a dummy made of concrete. The wreckage was photographed and sketched by the Danish Naval Officer-in-Charge on Bornholm, Lieutenant Commander Hasager Christiansen. When reported to British Intelligence, it was one of the first signs of Germany's aspirations to develop flying bombs and rockets, which were to become known as V-1. The Bornholm rocket turned out to be from
Peenemünde. The Soviet bombing of the two main towns on 7-8 May 1945 prepared the
landing of Soviet troops at Bornholm. Danish radio was not allowed to broadcast the news because it was thought it would spoil the liberation festivities in Denmark. 8 May 1945 was the
Victory in Europe Day. On 9 May, Soviet troops landed at Bornholm, and after a short fight, the German garrison (about 12,000 strong) surrendered. Soviet forces would leave the island on 5 April 1946. Later research found that the Soviet bombing of Bornholm resulted in approximately three thousand Danish civilians in
Rønne becoming homeless, while damaging a majority of the houses in
Nexø, fully destroying roughly one-tenth. Ten Danes were killed and thirty-five wounded, considered a low number, because many civilians were evacuated to shelters on the outskirts of the respective towns before the worst raids hit. It was not until 5 April 1946, that Soviet troops finally left Bornholm. After the war, Bornholm received aid from Sweden to rebuild Rønne and Nexø.
Cold War After the evacuation of their forces from Bornholm, the Soviets took the position that the stationing of foreign troops on Bornholm would be considered a declaration of war against the Soviet Union, and that Denmark should keep troops on it at all times to protect it from such foreign aggression. This policy remained in force after
NATO was formed, with Denmark as a founding member. The Soviets accepted the stationing there of Danish troops, which were part of NATO but viewed as militarily inferior elements of the alliance, but they strongly objected to the presence of other NATO troops on Bornholm, US troops in particular. On 5 March 1953, the day of
Stalin's death, Polish pilot
Franciszek Jarecki defected from the Eastern Bloc and landed a
MiG-15 fighter on the island. He was later granted asylum and rewarded for providing Western intelligence with the then-newest Soviet jet fighter. In 2017, Denmark's
Defence Intelligence Service decided to build a listening tower near
Østermarie, almost 90 meters high, to intercept radio communications across the Baltic Sea and in parts of Russia. == Municipality ==
