At the outset of World War II in September 1939, Denmark declared itself neutral, but that neutrality did not prevent Nazi Germany from occupying the country almost immediately after the outbreak of war; the occupation lasted until Germany's defeat. The decision to occupy Denmark was taken in Berlin on 17 December 1939.^[1] On 9 April 1940, Germany occupied Denmark in Operation Weserübung. The Danish government and king functioned in a relatively normal manner until 29 August 1943, when Germany placed Denmark under direct military occupation, which lasted until the Allied victory on 5 May 1945. Contrary to the situation in other countries under German occupation, most Danish institutions continued to function relatively normally until 1945. Both the Danish government and king remained in the country in an uneasy relationship between a democratic and a totalitarian system until 1943 when the Danish government stepped down in protest against German demands that included instituting the death penalty for sabotage.

Just over 3,000 Danes died as a direct result of the occupation.^[2] A further 2,000 volunteers of Free Corps Denmark and Waffen-SS, most of whom originated from the German minority of southern Denmark, died fighting on the Eastern Front^[3] while 1,072 merchant sailors died in Allied service.^[4] Overall, this represents a very low mortality rate compared to other occupied countries and most belligerent countries. Some Danes chose to collaborate during the occupation by joining the National Socialist Workers' Party of Denmark, Schalburg Corps, HIPO Corps and Peter Group (often with considerable overlap between the participants of the different groups). The National Socialist Workers' Party of Denmark participated in the 1943 Danish Folketing election, but despite significant support from Germany it only received 2.1% of the votes.^[5] In Denmark, the occupation period is known as Besættelsen (Danish for "the Occupation").^[6]

A resistance movement developed over the course of the war, and the vast majority of Danish Jews were rescued and sent to neutral Sweden in 1943 when German authorities ordered their internment as part of the Holocaust.^[7]

The occupation of Denmark was initially not an important objective for the German government. The decision to occupy its small northern neighbour was taken to facilitate a planned invasion of the strategically more important Norway, and as a precaution against the expected Allied response. German military planners believed that a base in the northern part of Jutland, specifically the airfield of Aalborg, would be essential to operations in Norway, and they began planning the occupation of parts of Denmark. However, as late as February 1940 no firm decision to occupy Denmark had been made.^[8] The issue was finally settled when Adolf Hitler personally crossed out the words die Nordspitze Jütlands ("the Northern tip of Jutland") and replaced them with Dä, a German abbreviation for Denmark.

Although the Danish territory of South Jutland was home to a significant German minority, and the province had been regained from Germany as a result of a plebiscite resulting from the Versailles Treaty, Germany was in no apparent hurry to reclaim it. In a much more vague and longer-term way, some Nazis hoped to incorporate Denmark into a greater "Nordic Union" at some stage, but these plans never materialized. Officially, Germany claimed to be protecting Denmark from Anglo-French attacks.^[9]

At 4:15 on the morning of 9 April 1940, German forces crossed the border into neutral Denmark. In a coordinated operation, German ships began disembarking troops at the docks in Copenhagen. Although outnumbered and poorly equipped, Danish soldiers in several parts of the country put up resistance, most notably the Royal Guard in Copenhagen and units in South Jutland. As the invasion began, German planes dropped the notorious OPROP! leaflets over Copenhagen calling on Danes to accept the German occupation peacefully, and claiming that Germany had occupied Denmark in order to protect it against Anglo-French attacks. Colonel Lunding from the Royal Danish Army's intelligence office later confirmed that Danish intelligence knew the attack would be coming on either 8 or 9 April and had warned the government accordingly. The Danish ambassador to Germany, Herluf Zahle, issued a similar warning which was also ignored.

As a result of the rapid turn of events, the Danish government did not have enough time to officially declare war on Germany. Denmark was in an untenable position in any event, however. Its territory and population were too small to hold out against Germany for any sustained period. Its flat land would have resulted in it being easily overrun by German panzers; Jutland, for instance, was immediately adjacent to Schleswig-Holstein to the south and was thus wide open to a panzer attack from there. Unlike Norway, Denmark had no mountain ranges from which drawn-out resistance could be conducted.^[10]

Sixteen Danish soldiers died in the invasion,^{[citation needed]} but after less than six hours the Danish government surrendered, believing that resistance was futile and hoping to work out an advantageous agreement with Germany. Not only was the flat Jutland territory a perfect area for the German army to operate in, the surprise attack on Copenhagen had made any attempt to defend Zealand impossible. The Germans had also been quick to establish control over the bridge across the Little Belt, thus gaining access to the island of Funen. Believing that further resistance would only result in the futile loss of more Danish lives, the Danish cabinet ultimately decided to bow to the German pressure "under protest".^[8] The German forces were technologically sophisticated and numerous; the Danish forces comparatively tiny and using obsolete equipment; partially a result of a pre-war policy of trying to avoid antagonizing Germany by not supplying the army with modern equipment.^{[citation needed]} Even stiff resistance from the Danes would not have lasted long. Questions have been raised around the apparent fact that the German forces did not seem to expect any resistance, invading with unarmored ships and vehicles.^[11]

After the occupation of Denmark, British forces from 12 April 1940 made a pre-emptive bloodless invasion of the Faroe Islands to prevent their occupation by German troops. Britain took over the areas where Denmark previously had given support, and the islands now became dependent on the United Kingdom, which began to participate in fishing production and supplied the islands with important goods.

The British fortified positions in strategically important locations in the Faroe Islands. Sounds and fjords were mined, and at the island of Vágar, British engineers built a military aviation base. Up to 8,000 British servicemembers were stationed in the islands, which at that time had 30,000 inhabitants.

The Faroe Islands were repeatedly attacked by German aircraft, suffering minimal damage. However, 25 Faroese ships were lost and 132 sailors died, corresponding to approx. 4% of the Faroese population at the time.

From 1918 until 1944, Iceland was self-governing, but the Danish king (King Christian X) was the head of state of both Denmark and Iceland. The United Kingdom occupied Iceland on 10 May 1940 to pre-empt German occupation, turning it over to the then-neutral United States in July 1941, before the latter's entry into the war in December 1941. Officially remaining neutral throughout World War II, Iceland became a fully independent republic on 17 June 1944.

On 9 April 1941, the Danish envoy to the United States, Henrik Kauffmann, signed a treaty with the U.S., authorizing it to defend Greenland and construct military stations there. Kauffmann was supported in this decision by the Danish diplomats in the United States and the local authorities in Greenland. Signing this treaty "in the name of the King" was a clear violation of his diplomatic powers, but Kauffmann argued that he would not receive orders from an occupied Copenhagen.

Historically, Denmark had a large amount of interaction with Germany. In 1920 the country regained possession of the northern part of Schleswig after losing the provinces during the Second Schleswig War in 1864. The Danish people were divided about what the best policy toward Germany might be. Few were ardent Nazis; some explored the economic possibilities of providing the German occupiers with supplies and goods; others eventually formed resistance groups towards the latter part of the war.^{[citation needed]} The majority of Danes, however, were unwillingly compliant towards the Germans.^{[citation needed]} Due to the relative ease of the occupation and copious amount of dairy products, Denmark earned the nickname the Cream Front (German: Sahnefront).^[12]

As a result of the cooperative attitude of the Danish authorities, German officials claimed that they would "respect Danish sovereignty and territorial integrity, as well as neutrality."^[9] The German authorities were inclined towards lenient terms with Denmark for several reasons: their only strong interest in Denmark, that of surplus agricultural products, could be supplied by price policy on food rather than by control and restriction (some German records indicate that the German administration had not fully realized this potential before the occupation took place, which can be doubted);^[13] there was serious concern that the Danish economy was so dependent upon trade with Britain that the occupation would create an economic collapse, and Danish officials capitalized on that fear to get early concessions for a reasonable form of cooperation;^[14] they also hoped to score propaganda points by making Denmark, in Hitler's words, "a model protectorate";^[15] on top of these more practical goals, Nazi race ideology held that Danes were "fellow Nordic Aryans," and could therefore to some extent be trusted to handle their domestic affairs.^{[citation needed]}

These factors combined to allow Denmark a very favourable relationship with Nazi Germany. The government remained somewhat intact, and the parliament continued to function more or less as it had before. They were able to maintain much of their former control over domestic policy.^[16] The police and judicial system remained in Danish hands, and unlike most occupied countries, King Christian X remained in the country as Danish head of state. The German Reich was formally represented by a Reichsbevollmächtigter ('Reich Plenipotentiary'), i.e. a diplomat accredited to the Sovereign, a post awarded to Cecil von Renthe-Fink, the German ambassador, and then in November 1942 to the lawyer and SS general Werner Best.

Danish public opinion generally backed the new government, particularly after the fall of France in June 1940.^[17] There was a general feeling that the unpleasant reality of German occupation must be confronted in the most realistic way possible, given the international situation. Politicians realized that they would have to try hard to maintain Denmark's privileged position by presenting a united front to the German authorities, so all of the mainstream democratic parties formed a new government together. Parliament and the government agreed to work closely together.^[8] Though the effect of this was close to the creation of a one-party state, it remained a representative government.

The Danish government was dominated by Social Democrats, including the pre-war prime minister Thorvald Stauning, who had been strongly opposed to the Nazi party.^{[citation needed]} Stauning himself was deeply depressed by the prospects for Europe under Nazism.^{[citation needed]} Nonetheless, his party pursued a strategy of cooperation, hoping to maintain democracy and Danish control in Denmark for as long as possible. There were many issues that they had to work out with Germany in the months after the occupation. In an effort to keep the Germans satisfied, they compromised Danish democracy and society in several fundamental ways:

• Newspaper articles and news reports "which might jeopardize German-Danish relations" were outlawed, in violation of the Danish constitutional prohibition against censorship.^[18]
• On the 22nd of June 1941, when Germany commenced its attack on the Soviet Union, the German authorities in Denmark demanded that Danish Communists should be arrested. The Danish government complied and using secret registers, the Danish police in the following days arrested 339 Communists. Of these 246, including the three Communist members of the Danish parliament, were imprisoned in the Horserød camp, in violation of the Danish constitution. On 22 August 1941, the Danish parliament passed the Communist Law, outlawing the Communist Party and Communist activities, in another violation of the Danish constitution. In 1943, about half of the Communists were transferred to Stutthof concentration camp, where 22 of them died.
• Following Germany's assault on the Soviet Union, Denmark joined the Anti-Comintern Pact, together with the fellow Nordic state of Finland. As a result, many Communists were found among the first members of the Danish resistance movement.
• Industrial production and trade was, partly due to geopolitical reality and economic necessity, redirected toward Germany. An overriding concern was a German fear of creating a burden if the Danish economy collapsed as it did after World War I. This sensitivity to Denmark's heavy reliance on foreign trade informed the German decision before the occupation to allow the Danes passage through their blockade.^[19] Denmark had traditionally been a major trading partner of both Britain and Germany. Many government officials saw expanded trade with Germany as vital to maintaining social order in Denmark.^[18] Increased unemployment and poverty were feared to lead to more of open revolt within the country, since Danes tended to blame all negative developments on the Germans. It was feared that any revolt would result in a crackdown by the German authorities.^[17]
• The Danish army was largely demobilized, although some units remained until August 1943. The army was allowed to maintain 2,200 men, as well as 1,100 auxiliary troops.^[20] Much of the fleet remained in port, but in Danish hands. In at least two towns, the army created secret weapons caches on 10 April 1940.^[21] On 23 April 1940,^[22] members of the Danish military intelligence established contacts with their British counterparts through the British diplomatic mission in Stockholm. They began dispatching intelligence reports to Britain by Autumn 1940. This traffic became regular and continued until the Germans dissolved the Danish army in 1943.^[22] Following the liberation of Denmark, Field Marshal Bernard Law Montgomery described the intelligence gathered in Denmark as "second to none".^[23]

In return for these concessions, the Danish cabinet rejected German demands for legislation discriminating against Denmark's Jewish minority. Demands to introduce the death penalty were likewise rebuffed, and so were German demands to allow German military courts jurisdiction over Danish citizens. Denmark also rejected demands for the transfer of Danish army units to German military use.

Stauning remained prime minister until his death in 1942, as head of a coalition cabinet encompassing all major political parties (the exceptions being the tiny Nazi party, and the Communist Party, which was outlawed in 1941). Vilhelm Buhl replaced him briefly, only to be replaced by foreign minister Erik Scavenius, who had been the main link to the Nazi authorities throughout the war. Scavenius was a diplomat, not an elected politician, and had an elitist approach to government.^[18] He was afraid that emotional public opinion would destabilize his attempts to build a compromise between Danish sovereignty and the realities of German occupation. Scavenius felt strongly that he was Denmark's most ardent defender. After the war there was much recrimination over his stance, particularly from members of the active resistance, who felt that he had hindered the cause of resistance and threatened Denmark's national honour. He felt that these people were vain, seeking to build their own reputations or political careers through emotionalism.

The Danish authorities were able to use their more cooperative stance to win important concessions for the country. They continually refused to enter a customs and currency union with Germany. Danes were concerned both about the negative economic effects of the German proposals, as well as the political ones. German officials did not want to risk their special relationship with Denmark by forcing an agreement on them, as they had done in other countries. The Danish government was also able to stall negotiations over the return of South Jutland to Germany, ban "closed-rank uniformed marches" that would have made nationalist German or Danish Nazi agitation more possible, keep National Socialists out of the government, and hold a relatively free election, with decidedly anti-Nazi results, in the middle of the war.^[18] Danish military officials also had access to sensitive German information, which they delivered to the Allies under government cover.^[24] The economic consequences of the occupation were also mitigated by German-Danish cooperation. Inflation rose sharply in the first year of the war, as the German Army spent a large amount of German military currency in Denmark, most importantly on military installations and troop deployments. Due to the Occupation, the National Bank of Denmark was compelled to exchange German currency for Danish notes, effectively granting the Germans a gigantic unsecured loan with only vague promises that the money would eventually be paid, something which never happened. The Danish government was later able to renegotiate the Germans' arbitrary exchange rate between the German military currency and the Danish krone to reduce this problem.^[16]

The success most often alluded to in regard to the Danish policy toward Germany is the protection of the Jewish minority in Denmark. Throughout the years of its hold on power, the government consistently refused to accept German demands regarding the Jews.^[25] The authorities would not enact special laws concerning Jews, and their civil rights remained equal with those of the rest of the population. German authorities became increasingly exasperated with this position but concluded that any attempt to remove or mistreat Jews would be "politically unacceptable."^[26] Even the Gestapo officer Werner Best, plenipotentiary in Denmark from November 1942, believed that any attempt to remove the Jews would be enormously disruptive to the relationship between the two governments and recommended against any action concerning the Jews of Denmark.

Christian X remained in Denmark throughout the war, a symbol of courage much appreciated by his subjects.

On 29 June 1941, days after the invasion of the USSR, Free Corps Denmark (Danish: Frikorps Danmark) was founded as a corps of Danish volunteers to fight against the Soviet Union. Free Corps Denmark was set up at the initiative of the SS and DNSAP who approached Lieutenant-Colonel C.P. Kryssing of the Danish army shortly after the invasion of the USSR had begun. The Nazi paper Fædrelandet [da] proclaimed the creation of the corps on 29 June 1941.^[27]

According to Danish law, it was not illegal to join a foreign army, but active recruiting on Danish soil was illegal. The SS disregarded this law and began recruiting efforts – predominantly recruiting Danish Nazis and members of the German-speaking minority.^[27] The Danish government discovered this and decided to concentrate on persuading the Germans not to recruit underage boys. General Prior wanted to remove Kryssing and his designated second-in-command but decided to consult the cabinet. It agreed that Kryssing should be removed in its meeting on 2 July 1941, but this decision was later withdrawn when Erik Scavenius—who had not attended the original meeting—returned from negotiations and announced that he had reached an agreement with Renthe-Fink that soldiers wishing to join this corps could be given leave until further notice. The government issued an announcement stating that "Lieut. Colonel C. P. Kryssing, Chief of the 5th Artillery reg., Holbæk, has with the consent of the Royal Danish Government assumed command over 'Free Corps Denmark'". The Danish text only explicitly said that the government recognized that Kryssing had been given a new command; it did not sanction the creation of the corps, which had already happened without its creators asking the government's consent.^[27] In July 1941 Heinrich Himmler complained that Denmark was unofficially trying to stop recruitment since the word ran in the army that anyone joining would be committing treason. The government later instructed the army and navy not to obstruct applications from soldiers wishing to leave active duty and join the corps.

A 1998 study showed that the average recruit to Free Corps Denmark was a Nazi, a member of the German minority in Denmark, or both, and that recruitment was very broad socially.^[27] Historian Bo Lidegaard notes: "The relationship between the population and the corps was freezing cold, and legionnaires on leave time and again came into fights, with civilians meeting the corps' volunteers with massive contempt." Lidegaard gives the following figures for 1941: 6,000 Danish citizens had signed up to German army duty; 1,500 of these belonged to the German minority in Denmark.^[27]

On 20 November 1941, five months after the invasion of the USSR, the Danish government received a German "invitation" to join the Anti-Comintern Pact. Finland accepted reluctantly on 25 November and stated that it presumed that Denmark would also attend the ceremony (effectively conditioning its own attendance). Erik Scavenius argued that Denmark should sign the pact but the Cabinet ministers refused, stating that this would violate the policy of neutrality.^[29] Scavenius reported this decision to Renthe-Fink. Fink replied on 21 November that "Germany would be unable to comprehend" a Danish rejection and demanded this decision be reversed before the end of the day. He assured Scavenius that the pact contained neither "political or other obligations" (i.e., going to war with the USSR). At a cabinet meeting the same day, it was suggested to seek written confirmation of this promise in an addendum to the protocol. Stauning agreed on these terms since it would effectively make the signing meaningless. The Danish foreign office drew up a list of four terms that stated that Denmark only committed itself to "police action" in Denmark and that the nation remained neutral. The German foreign ministry agreed to the terms, provided that the protocol was not made public, which was the intent of the Danish foreign ministry.

As Berlin grew tired of waiting, Joachim von Ribbentrop called Copenhagen on 23 November threatening to "cancel the peaceful occupation" unless Denmark complied. On 23 November, the Wehrmacht in Denmark was put on alert, and Renthe-Fink met Stauning and Foreign Minister Munch at 10 AM stating that there would be no room for "parliamentary excuses". If the German demands were not met Germany "would no longer be committed by the promises given on 9 April 1940" (the threat of a state of war, a Nazi government, and territorial dismemberment). In a Cabinet meeting at 2 PM that day, Stauning, Scavenius, Munch and two additional ministers advocated accession; seven ministers opposed. In a meeting the same day in the Nine Man committee, three more ministers caved in, most notably Vilhelm Buhl, stating "Cooperation is the last shred of our defence". Prime Minister Stauning's notes from the day stated: The objective is a political positioning. But this was established by the occupation. The danger of saying no—I would not like to see a Terboven here. Sign with addendum—that modifies the pact.^[29]

Scavenius boarded a train and headed for Berlin, where he arrived on Monday 24 November. The next crisis came when he was met by Renthe-Fink, who informed him that Ribbentrop had informed Fink that there had been a "misunderstanding" regarding the four clauses and that clause 2 would be deleted. This had specified that Denmark only had police-like obligations. Scavenius had a strict mandate not to change a sentence and stated that he would be unable to return to Copenhagen with a different content from the one agreed upon, but that he was willing to reopen negotiations to clarify the matter further. This reply enraged Ribbentrop (and rumours claim that he was considering ordering the SS to arrest Scavenius). The task fell to German diplomat Ernst von Weizsäcker to patch up a compromise. He watered down the wording but left the content pretty intact. Nonetheless, for Scavenius it was a strong setback that the four clauses would now only get the status of a unilateral Danish declaration (Aktennotitz) with a comment on it by Fink that its content "no doubt" was in compliance with the pact. Furthermore, he was instructed to give a public speech while abstaining from mentioning the four clauses but only making general statements about Denmark's status as a neutral nation. Scavenius signed the pact. At the following reception, the Italian ambassador described Scavenius as "a fish dragged on land ... a small old gentleman in a suit asking himself how on earth he got to this place". Lidegaard comments that the old man remained defiant: during a conversation with Ribbentrop in which the latter complained about the "barbarous cannibalism" of Russian POWs, Scavenius rhetorically asked if that statement meant that Germany didn't feed her prisoners.^[29]

When news of the signing reached Denmark, it left the population outraged, and rumours immediately spread about what Denmark had now committed itself to. The cabinet sent a car to pick up Scavenius at the ferry, to keep him from needing to ride the train alone to Copenhagen. At the same time a large demonstration gathered outside of Parliament, which led the Minister of Justice, Eigil Thune Jacobsen [da] to remark that he did not like to see Danish police beating up students singing patriotic songs. When Scavenius had returned to Copenhagen, he asked the cabinet to debate once and for all where the red lines existed in Danish relations with Germany. This debate concluded that three red lines existed:

1. No legislation discriminating against Jews,
2. Denmark should never join the Axis Pact between Germany, Italy, and Japan,
3. No unit of the Danish army should ever fight against foreign forces.

To the surprise of many, Scavenius accepted these instructions without hesitation.^[29]

In October 1942, Hitler transmitted a long, flattering birthday telegram to King Christian. The King replied with a simple "Spreche Meinen besten Dank aus. Chr. Rex" ("Giving my best thanks. King Christian") sending the Führer into a state of rage at this deliberate slight, and seriously damaging Danish relations with Germany. Hitler immediately recalled his ambassador and expelled the Danish ambassador from Germany. The plenipotentiary, Renthe-Fink, was replaced by Werner Best and orders to crack down in Denmark were issued. Hitler also demanded that Erik Scavenius become prime minister, and all remaining Danish troops were ordered out of Jutland.

As the war dragged on, the Danish population became increasingly hostile to the Germans. Soldiers stationed in Denmark had found most of the population cold and distant from the beginning of the occupation, but their willingness to cooperate had made the relationship workable. The government had attempted to discourage sabotage and violent resistance to the occupation, but by the autumn of 1942 the numbers of violent acts of resistance were increasing steadily to the point that Germany declared Denmark "enemy territory" for the first time.^[18] After the battles of Stalingrad and El-Alamein the incidents of resistance, violent and symbolic, increased rapidly.

In March 1943 the Germans allowed a general election to be held. The voter turnout was 89.5%, the highest in any Danish parliamentary election, and 94% cast their ballots for one of the democratic parties behind the cooperation policy while 2.2% voted for the anti-cooperation Dansk Samling.^[30] 2.1% voted for the National Socialist Workers' Party of Denmark, almost corresponding to the 1.8% the party had received in the 1939 elections. The election, discontent, and a growing feeling of optimism that Germany would be defeated led to widespread strikes and civil disturbances in the summer of 1943. The Danish government refused to deal with the situation to the satisfaction of the Germans, who gave an ultimatum to the government, including the following demands, on 28 August 1943:

• A ban on people assembling in public,
• outlawing strikes, the introduction of a curfew,
• censorship conducted with German assistance,
• special (German military) courts should be introduced, and
• death penalty in cases of sabotage.

In addition, the city of Odense was ordered to pay a fine of 1 million kroner for the death of a German soldier killed in that city and hostages were to be held as security.^[31]

The Danish government refused, so on 29 August 1943 the Germans officially dissolved the Danish government and instituted martial law. The Danish cabinet handed in its resignation, but since King Christian never officially accepted it, the government remained functioning de jure until the end of the war. In reality—largely due to the initiative of the permanent secretary of foreign affairs Nils Svenningsen^[32]—all day-to-day business was handed over to Permanent Secretaries, who each effectively ran his own ministry. The Germans administered the rest of the country, and the Danish Parliament did not convene for the remainder of the occupation. As the ministry of foreign affairs responsible for all negotiations with the Germans, Nils Svenningsen had a leading position in the government.^[33]

In anticipation of Operation Safari, the Royal Danish Navy had instructed its captains to resist any German attempts to assume control over their vessels. The navy managed to scuttle 32 of its larger ships, while Germany succeeded in seizing 14 of the larger and 50 of the smaller vessels (patruljekuttere or "patrol cutters"). The Germans later succeeded in raising and refitting 15 of the sunken ships. During the scuttling of the Danish fleet, a number of vessels were ordered to attempt an escape to Swedish waters, and 13 vessels succeeded in this attempt, including four larger ships; two other larger vessels remained at safe harbour in Greenland.^[34][35] The coastal defence ship HDMS Niels Juel attempted to break out of the Isefjord, but was attacked by Stukas and forced to run aground. By the autumn of 1944, the ships in Sweden officially formed a Danish naval flotilla in exile.^[36] In 1943, Swedish authorities allowed 500 Danish soldiers in Sweden to train themselves as "police troops". By the autumn of 1944, Sweden increased this number to 4,800 and recognized the entire unit as a Danish brigade in exile.^[37] Danish collaboration continued on the administrative level, with Danish bureaucracy functioning under German command.

In September 1943, a variety of resistance groups grouped together into the Danish Freedom Council, which coordinated resistance activities. A high-profile resister was former government minister John Christmas Møller, who had fled to England in 1942 and became a widely popular commentator because of his broadcasts to the nation on BBC radio.

After the fall of the government, Denmark was exposed to the full extent of occupational rule. In October the Germans decided to remove all Jews from Denmark, German diplomat Georg Ferdinand Duckwitz leaked Nazi plans, and swift action by Danish civilians transported the vast majority of Danish Jews to safety in neutral Sweden in fishing vessels and motorboats. The entire evacuation lasted two months and one man helped ferry more than 1,400 Jews to safety.^[38] Unencumbered by government opposition, sabotage increased greatly in frequency and severity, though it was rarely of very serious concern to the Germans. Nonetheless, the Danish resistance movement had some successes, such as on D-Day when the train network in Denmark was disrupted for days, delaying the arrival of German reinforcements in Normandy. An underground government was established, and the illegal press flourished. Allied governments, which had been sceptical about the country's commitment to fight Germany, began recognizing Denmark as a full ally.^[18]

The permanent secretary of the ministry of foreign affairs, Nils Svenningsen, in January 1944 suggested establishing a Danish camp, to avoid deportations to Germany.^[39] Werner Best accepted this suggestion, but on condition that this camp was built close to the German border. Frøslev Prison Camp was set up in August 1944, solely to keep Danish Jews and other prisoners within Denmark's borders.^[40]

The Gestapo had limited trust in the Danish police force, which had a total 10,000 members;^[41] 1,960 of them were arrested and deported to Germany on 19 September 1944.

Denmark faced some serious economic problems during the war. The Danish economy was fundamentally hurt by the rising cost of raw material imports such as coal and oil. Furthermore, Denmark lost its main trading partner at that point, the UK. During years of occupation the Danish economy was more and more aligned on meeting German demands, which mainly meant agrarian products. The Danish authorities took an active part in the development and even initiated negotiations on a customs union. Those negotiations failed on the question whether the Danish krone should be abolished.^[42]

The blockade against Germany affected Denmark too with unfortunate results. Since the country has virtually no natural resources of its own it was very vulnerable to these price shocks and shortages. The government had foreseen the possibility of coal and oil shortages and had stockpiled some before the war, which, combined with rationing, prevented some of the worst potential problems from coming to the country. The disruptions to the European trading network were also damaging to the economy, but all things considered, Denmark did quite well compared to other countries during the war.

The country, at least certain sections of it, did so well that it has been open to the accusation of profiteering from the war. After the war there was some effort to find and punish profiteers, but the consequences and scope of these trials were far less severe than in many other countries, largely a reflection of the general acceptance of the realistic need for cooperation with Germany. On the whole, though the country fared relatively well, this is only a relative measure. Phil Giltner has worked out that Germany had a "debt" of roughly 6.9 billion kroner to Denmark as a whole.^[16] This means that they had taken far more out of the Danish economy than they had put in, aside from the negative side effects of the war on trade. The German debt had accumulated due to an arrangement with the Danish central bank, in which the German occupation forces could draw on a special account there to pay their bills from Danish suppliers. Exports to Germany were also largely settled this way. The arrangement was agreed to for fear of German soldiers helping themselves without paying, and the conflicts that might follow. It also meant that the Danish central bank was picking up a large part of the tab for the German occupation, and that the money supply rose drastically as a result.^[43]

The Danish National Bank estimates that the occupation had resulted in the printing press increasing the currency supply from the pre-war figure of 400 million kroner to 1,600 million, much of which ended up in the hands of war profiteers. In July 1945, two months after the liberation of Denmark, the Danish Parliament passed an emergency law initiating a currency reform, making all old banknotes void. A small number of employees at the National Bank had clandestinely begun the production of new banknotes in late 1943. The production of new notes happened without the knowledge of the German forces located at the bank, and by the spring of 1945 the bank's stock of notes was sufficient to initiate the exchange.^[44] The law required was passed hastily on Friday 20 July and published the same day; it also closed all shops for the weekend. By Monday 23 July, all old notes were officially outlawed as legal tender and any note not declared in a bank by 30 July would lose its value. This law allowed any Dane to exchange a total of 100 kroner to new notes, no questions asked. An amount up to 500 kroner could be exchanged, provided the owner signed a written statement explaining its origins. Any amount above this level would be deposited in an escrow account and only released or exchanged following scrutiny by tax officials examining the validity of the person's statement about the origins of this wealth. All existing bank accounts were also scrutinized. Multiple exchanges of cash by the same person were avoided by the requirement that currency would only be exchanged to anybody also handing in a specified ration stamp, previously issued in a different context, which had not yet been authorized for use.^[45] The exchange resulted in a significant drop in the currency supply, and around 20% of the 3,000 million kroner property declared had not previously been registered by the tax authorities.^[44] Estimates vary for the amounts of currency simply destroyed by its owners. All banknotes issued since the changeover date remain valid indefinitely; earlier ones are not valid.

Most of Denmark was liberated from German rule in May 1945 by British forces commanded by Field Marshal Bernard Montgomery; the easternmost island of Bornholm was liberated by Soviet forces, who remained there for almost a year. On 5 April 1946 the last Soviets left Bornholm. The end of German rule is in Denmark known as Befrielsen (the Liberation).^[46][47]

Although Denmark was spared many of the difficulties other areas of Europe suffered, its population still experienced hardships, particularly after the Germans took charge in 1943. Yet on the whole, Denmark can be said to have suffered the least of all the European combatants from the war.^[16] Many were killed and imprisoned because of their work resisting the German authorities. There were small bombing raids on select targets in the country, but nothing comparable to that suffered by, for instance, neighbouring Norway or the Netherlands. One area that was badly damaged was the island of Bornholm, largely due to Soviet bombardment of the German garrison there in the very last days of the war.

About 380 members of the resistance were killed during the war: they are commemorated in Ryvangen Memorial Park. Roughly 900 Danish civilians were killed in a variety of ways: either by being caught in air raids, killed during civil disturbances, or in reprisal killings, the so-called "clearing" murders. Thirty-nine Danish soldiers were killed or injured during the invasion, and four were killed on 29 August 1943 when the Germans dissolved the Danish government. Some sources estimate that about 360 Danes died in concentration camps. The largest groups of fatalities were amongst Danish merchant sailors, who continued to operate throughout the war, most falling victim to submarines. Some 1,850 sailors died. Just over 100 soldiers died as part of Allied forces.^{[citation needed]}

Approximately 6,000 Danes were sent to concentration camps during World War II,^[48] of whom about 600 (10%) died. In comparison with other countries this is a relatively low mortality rate in the concentration camps.

After the war, 40,000 people were arrested on suspicion of collaboration. Of these, 13,500 were punished in some way. 78 received death sentences, of which 46 were carried out. Most received prison sentences of under four years. Many people criticized the process for victimizing "small" people disproportionately, while many politicians and businesses were left untouched. One difficult issue was deciding what to do with collaborators who were essentially "following orders" that their own government had given them, such as business executives who had been encouraged to work with the Germans.

Although some members of the resistance tried to organize new political parties after the war to reshape the political order in Denmark, they were unable to do so. The only party that appeared to receive a significant boost from resistance was the Communist Party. The Communists received about one-eighth of the popular vote in the October 1945 elections.

On 5 May 1945, Denmark was officially free of German control. Citizens all over the country took down the black shades that had been used to cover their windows during bombing raids and made bonfires of them in the streets. Allied troops (mostly Soviet soldiers) were released from prisons all over the country and paraded down streets in Copenhagen, Aarhus, and other cities. In Aarhus, young women known or believed to have had relationships with German soldiers were dragged through the streets before crowds of people and had most of their hair cut off. They were then forced to march down the street to be humiliated.^{[citation needed]}

After the end of hostilities, over two thousand German prisoners of war were made to clear the vast minefields that had been laid on the west coast of Jutland, nearly half of them being either killed or wounded in the process. As part of a controversial agreement reached by the German Commander General Georg Lindemann, the Danish Government and the British Armed Forces, German soldiers with experience in defusing mines were in charge of clearing the mine fields.^{[49][50][better source needed]}

In the final weeks of the war, between 9 February and 9 May, several hundred thousand German refugees fled across the Baltic Sea, fleeing the advancing Soviet Army. For the most part, the refugees were from East Prussia and Pomerania. Many of the refugees were women, children, or elderly. Many were malnourished, exhausted, or seriously ill. A third of the refugees were younger than 15 years old.

The German authorities gave the refugees a privileged status, seizing Danish schools, church houses, hotels, factories, and sports facilities for refugee housing. At the same time, thousands of Danes were deported to German prisons and concentration camps. German terror against Danish resistance fighters and civilians increased in these final months. The general sentiment among Danes saw the arrival of refugees as a new, violent German occupation.

At the time of the German capitulation there were about 250,000 German refugees in Denmark. Already at the end of April, the German military authorities seemed to have lost control of the situation; many refugees had no food, the sick were not treated, mortality was high, and unburied dead bodies were stored in warehouses and cellars—although this was the result of different priorities in negotiations on aid between German and Danish authorities. The Danish negotiators, led by secretary of state Nils Svenningsen, would only agree provided that approximately 4,000 Danish citizens, mainly policemen, who were being detained in German concentration camps, were liberated. German authorities, on the other hand, would only agree if those policemen would take an active part in defeating the Danish resistance.^[51]

At the capitulation, the refugee administration was handed over to Danish authorities. Refugees were gradually moved from over 1,000 smaller locations to new-built camps or previous German military barracks, some of which held over 20,000 refugees. The largest of the camps, Oksbøl Refugee Camp, in Oksbøl on the west coast of Jutland, held 37,000 refugees. Camps were placed behind barbed wire and guarded by military personnel to avoid contact with the Danish population.

In some of the camps, food rations were scarce and medical care was inadequate. In 1945 alone, more than 13,000 people died, among them some 7,000 children under the age of five.^[52] The situation was worst in the months right before and after the capitulation when Danish hospitals and doctors were reluctant to treat German refugees. The reason for this was not only anti-German resentment, but also lack of resources, the time needed to rebuild administrative structures, and the fear of epidemic diseases which were highly prevalent among the refugees. Instead, Danish authorities established a camp-internal medical system with German medical personnel which took some time to work adequately. In the camps, there was school education for children up to the upper secondary level, work duty for adults, study circles, theatre, music, and self-issued German newspapers. After initial inadequacy, food rations became more sufficient.

On 24 July 1945, the British occupation force, contrary to Danish expectations, decided that the refugees must stay in Denmark until the situation in Germany had stabilized. The first refugees were returned to Germany in November 1946 and the last ones in February 1949. Very few stayed in Denmark for good.^[53]

The policy of the government, called samarbejdspolitikken (cooperation policy) is one of the most controversial issues in Danish history.^[54] Some historians argue that the relatively accommodating policy which did not actively resist the occupation was the only realistic way of safeguarding Danish democracy and people.^[55] However, others argue that accommodation was taken too far, was uniquely compliant when compared to other democratic governments in Europe, and cannot be seen as part of a coherent long-term strategy to protect democracy in Denmark or Europe.^[54] In 2003 Danish Prime Minister Anders Fogh Rasmussen characterized the cooperation as "morally unjustifiable," the only time a Danish leader had condemned the war-era leadership,^[56] even though Anders Fogh Rasmussen's opponents construed it as a justification for his own ambitions, in connection with the invasion of Iraq in 2003.^[57][58]
