Between 1523 and Sweden's

The Russian Empire was an empire that spanned most of northern Eurasia from its establishment in November 1721 until the proclamation of the Russian Republic in September 1917. At its height in the late 19th century, it covered about , roughl ...

in 1809, all of Finland had been ceded to Russia and Sweden was reduced to two thirds of its former size.
As the end of the 19th century approached, and the beginning of the 20th began, Sweden, like many other nations, became beset by
strikes and public disorder. Appalling working conditions were no longer tolerated and the working class was rising against the state. In 1908 alone, there were about 300 strikes in Sweden. By 1917, Sweden's need for a new political system was apparent from these riots. Sweden had
remained neutral during World War One but with a tendency to side with the

But even these reforms were seen as far too radical by some conservatives. Some wanted strong leadership and did not believe in democracy. In the 1920s and 1930s, confrontations between employers and employees in Sweden continued. In 1931, this culminated with the

kronor, but during the war, output exceeded SEK 1 billion (US$240 million).
Military balance
Sweden's long-standing policy of neutrality was tested on many occasions during the 1930s. The challenges came from a strongly rejuvenated, nationalistic Germany. From 1919 until 1935, Sweden had been an active supporter of the
League of Nations

Pre-war preparations
In 1936, the Swedish government started to heighten its military preparedness as the international situation worsened. Military spending in Sweden went from US$37 million in 1936, to $50 million in 1937, to $58.6 million in 1938, and then increased over fivefold to $322.3 million in 1939. During World War II itself, military spending peaked at $527.6 million in 1942.
Not only was the Swedish government buying material to strengthen its defences, it began
drafting conscripts. On 6 May 1938, the government called up all those aged 15 for short periods of training. In addition to this, the Swedish
Cabinet ordered that one quarter of those conscripted in 1938 should be retained for further training.

Measures to protect against air raids

Beginning in the autumn of 1938, efforts were made to protect cities and towns from air raids. In order to decrease the risk of large fires breaking out the attics of all buildings were cleared in the larger towns. After the outbreak of war all windows in towns were to be covered quickly in the event of an air raid. Historic buildings such as medieval churches were in many cases protected by moving valuable objects or covering external ornaments. The vast sculpture group ''Saint George and the Dragon,'' located in Storkyrkan in Stockholm, was disassembled and evacuated to an underground space in April 1940.

Allies had intended to use the Soviet attack on Finland in November 1939 as cover for seizing the important Swedish iron ore deposits in the north, in addition to the Norwegian harbours through which this ore was shipped to Germany. The plan was to get Norwegian and Swedish permission to send an

Scandinavian reluctance to allow Allied troops onto their territory had halted the original Allied plan for using aid to Finland as a pretext for moving in troops, but on 12 March 1940, the Allies decided to try a "semi-peaceful" invasion nonetheless. Troops were to be landed in Norway, and proceed into Sweden to capture the Swedish iron ore mines. However, if serious military resistance was encountered, they were not to press the issue. The plan was abandoned with the ending of the Winter War on 13 March. The Germans were partly aware of these Allied intentions, as they had intercepted radio traffic showing that Allied transport groups were being readied. A few days later, they also intercepted messages confirming that the Allies had abandoned their plan and were to redeploy their forces.
German plans for an invasion of Norway continued, since Hitler feared that the Allies were nonetheless intent upon launching their own invasion. 9 April was set as the date of

When Germany invaded both Denmark and Norway on 9 April 1940, the 100,000 Swedish soldiers who had been deployed along the Finnish border in northern Sweden were in the process of being demobilized, owing to the end of the Winter War there. Before the outbreak of hostilities, Sweden had had no plans for defending Norway or any defence strategy against a German invasion from the direction of Norway. Moreover, an agreement from the
dissolution of the union between Norway and Sweden in 1905 stated that no fortification was allowed along this border. One of Germany's demands on Sweden, as Germany's invasion progressed, was that Sweden was not to mobilize. However, Sweden re-organized its system of mobilization to allow for personal order by letter to be made possible as an alternative to official proclamation, so that 320,000 men were able to be raised in a few weeks. This was called "The Organization" and was barely different from a full mobilization when completed. Sweden also started to build fortifications at the Norwegian border and along the coast of

In his book ''Blodsporet'' ("The Blood Track"), Espen Eidum detailed how, at the request of Adolf Hitler, Nazi Germany sent three trains with 30 to 40 sealed carriages through Sweden to the battle of Narvik. These trains ostensibly transported medical personnel and food for the wounded German soldiers in Narvik. However, in reality there were 17 soldiers for every medical officer or orderly. Sweden knew that the trains were being used to transport troops because a Swedish representative in Berlin reported that he had watched them board. The trains also transported heavy artillery, anti-aircraft guns, ammunition, and communications and supply equipment.

and elsewhere. Germany was forced into a more defensive position as the Allied forces achieved success on the battlefield. It was becoming increasingly apparent to Sweden that Germany was unlikely to win the war. Prior to 1943, Sweden's policy of neutrality had been largely under the close scrutiny of Germany. After August and September 1943, however, Sweden was increasingly able to resist German demands and to soften its stance to Allied pressure. However, despite Germany's new, defensive posture, Sweden's constant fear was that the unexpected would happen, an attitude that continued until the very end of the war. With Germany's weakening position came stronger demands from the Allies. They pushed for Sweden to abandon its trade with Germany and to stop all
German troop movements over Swedish soil. Sweden accepted payments from the Allies to compensate for this loss of income through reduced trade with Germany, but continued to sell steel and machine parts to Nazi Germany at inflated ''smugglers' rates''.

On 21 February, seven Soviet bomber planes appeared in the village Pajala, 10 kilometres from the border to Finland. Pajala was hit by more than 130 bombs, causing damage to local buildings. A bomb hit the local school gym, where the Norrland Dragoon Regiment were stationed at the time, but did not detonate. There were two injuries during the bombing of Pajala.
On 22 February, Soviet bombing of Stockholm and Strängnäs in 1944, Stockholm was bombed by four Soviet bombers, a 100 kg bomb destroying a newly opened theatre, injuring two Swedish soldiers. Sweden concluded that this instance was by mistake, but the Soviet Union refused to acknowledge the involvement of its bombers in the raid when requested to clarify. Though the event remains unclear, a theory developed that it was a deliberate attack in response to Sweden rejecting Soviet appeals for Vasily Sidorenko, who had been arrested for espionage, to be released.
Humanitarian effort
Before the war, thousands of European Jews sought temporary refuge in Sweden, and were denied. As the war began to shift in favor of the Allies, the Swedes changed their strategy with regard to aiding the precariously situated European Jews, who up to that point had been refused refuge in Sweden. The first shift in Sweden's stance towards Jews occurred in 1942. When the Germans began their campaign of persecution against the Jews of Norway, the Swedish government accepted 900 Jewish refugees, slightly more than half of Norway's Jewish population.
In 1943, Sweden received nearly all of Rescue of the Danish Jews, Denmark's 8,000 Jews (along with 9,000 Danish Christians who were seeking refuge from conditions of war). With the dissolution of the Danish government in the summer of 1943, the German authorities had decided to deport Denmark's Jewish population to concentration camps. However, the Danes successfully ferried all but 450 of the Danish Jews across the straits between Copenhagen and the Swedish mainland, across waters that were patrolled by German Schnellboots, in an unprecedented Rescue of the Danish Jews, rescue effort. Once in Sweden, the Danish Jews were granted asylum and taken in by Swedish families. Many stayed in Sweden after the war. Sweden also received refugees from Finland and Norway, including some of Norway's Jews. All this, as well as the protection of Sweden's own Jewish population, was made possible by Sweden's neutrality. A daily newspaper in Sweden, the ''Svenska Dagbladet'' said that Sweden did more to assist and save Jews than any other country.
Neutrality also allowed Sweden to have physical access to Germany, which was not only useful to Swedish intelligence but to Allied intelligence as well. Employees at Allmänna Svenska Elektriska Aktiebolaget, Asea, LM Ericsson and the Swedish Match Factory (Svenska Tändsticksfabriken) acted as couriers for the Polish resistance movement in World War II, Polish resistance.[ Gustav V, King Gustav V of Sweden attempted to use his diplomatic connections with German leaders to convince them to treat Jews more humanely, as evidenced through his correspondence, although to little effect. Count Folke Bernadotte, a relative of the Swedish royal family, was able to communicate with the German government and relay information back to Sweden, as did other diplomats. He also contributed in saving 15,000 prisoners from concentration camps, as did Valdemar Langlet and the famous diplomat Raoul Wallenberg, who may have saved up to 100,000 Hungarian Jews.

Press freedom
The Swedish public's sentiments were widely published in the Media in Sweden, Swedish press, causing many protests from the German government and prompting the Swedish government to censorship, censor some areas of the press on a limited basis. In Sweden during this time, the press fell under the control of several authorities, despite contemporary claims that the Swedish press was free. The Swedish Government Information Board determined what military information could be released and what information should remain secret. The Swedish Press Council served as a self-regulatory body, promoting "good relations between the press and the public authorities and to serve as an instrument of self-discipline for the press". The Swedish Press Council issued warnings, both public and confidential, to those whom it considered to be abusing the freedom of the press.
The Swedish government was concerned that its neutrality might be compromised should the press become too vocal in its opinions. Both the Swedish Press Council and the Information Board issued advice such as: "As far as the received material permits, attempts should be made not to give prominence to the reports of one side at the expense of the other", or: "Headlines, whether on the billboards or in the newspapers, should be worded in such a way as to avoid favoring one side or the other", and: "Editorials and surveys as well as articles discussing military events or the military situation, should be strictly objective."
During World War II, six newspapers were de facto banned from distribution: Ture Nerman's ''Trots Allt!'', the Nazi publication ''Sverige Fritt'' and ''Ny Dag'', ''Arbetar-Tidningen'', ''Norrskensflamman'' and ''Sydsvenska Kuriren'' (the last four were organs of the Communist Party of Sweden). A ban on the transport of these newspapers was imposed, since the printing of newspapers was protected in the Swedish constitution. There were indications that the bans imposed on the communist newspapers had served their political purposes by impressing the Germans, whilst at the same time not really restricting the work of the media.

Perhaps the most important aspect of Sweden's concessions to Germany during the Second World War was the extensive export of iron ore for use in the German arms industry, weapons industry, reaching ten million tons per year. As Germany's preparations for war became more apparent and the risk of another war became obvious, international interest in Swedish iron ore increased. At the time, British intelligence had estimated that German industry relied heavily on Swedish iron ore and a decrease or halt in Swedish ore exports could have a disastrous effect on Germany's military efforts. Ralph Glyn, 1st Baron Glyn, Sir Ralph Glyn, a British Member of Parliament, claimed that a cessation of Swedish iron ore exports would bring the war to an end within months. Winston Churchill himself said the following about the Swedish ore exports in an internal memo to the cabinet discussing the Norwegian trade route with shipments of Swedish iron ore.
Given that Britain had been unable to prevent the successful invasion by Nazi Germany of both France and Norway, the Swedish government was not convinced that the British could protect them and opted to continue exports. The iron ore provided much needed gold bullion, food and coal from Germany. The iron ore was transported by sea from the Norwegian town of Narvik and from Luleå

in northern Sweden. These shipments were subject to attacks from British aircraft and submarines in the Atlantic and North Sea and by Soviet submarines in the Baltic Sea. About 70 vessels were sunk and 200 sailors killed during the war.
Responding to German appeals for volunteers to fight the Soviet Union, approximately 270 Swedes enlisted in Germany's Waffen-SS, and saw combat against Soviet troops on the Eastern Front (World War II), Eastern Front. This was a choice made by individual Swedish citizens, contrary to Swedish government policy. Their number was small compared to occupied countries, in which officials encouraged enlisting for the Eastern Front (Norway 6,000; Denmark 6,000; France 11,000; Netherlands 20,000). Roughly 50 Swedish Waffen-SS men were killed or went missing in action. Most of the veterans were classified as security risks and spied on by Swedish intelligence for the rest of their lives. Security Police's archives showed that some of the men were implicated as direct participants in the killings of Jews. No Swedes stood trial for serving in the Waffen-SS, albeit some of them were prosecuted for espionage or desertion.
With a blockade of the Skagerrak
The Skagerrak (; , , ) is a strait running between the North Jutlandic Island of Denmark, the east coast of Norway and the west coast of Sweden, connecting the North Sea and the Kattegat sea.

straits between Norway and the northern tip of Denmark, the Swedish merchant navy found itself physically divided. The vessels that were inside the Baltic Sea traded goods with Germany during the war, whilst the greater number of vessels was leased to the Allies for convoy shipping. Approximately 1,500 Swedish sailors perished during the war, mostly victims of mines and U-boat attacks. German merchant raiders, too, would stop and capture or destroy Swedish vessels carrying cargoes for allies. For example, this was the fate of MVs ''Trolleholm'' and ''Sir Ernest Cassel'', both destroyed by the German auxiliary cruiser Thor, German auxiliary cruiser ''Thor''; the same ''Thor'' also accidentally collided with HM ''Bothnia'' in the fog while carrying cargoes for Germany causing it to sink. In the meantime, other German merchant raiders would masquerade as Swedish merchant vessels.
To the Allies
Sweden made efforts to help the Allied Forces. From May 1940, a large part of the Swedish merchant navy that found itself outside the Baltic Sea region, totalling about 8,000 seamen, was leased to Britain. 300 Swedes traveled to Norway to fight the German invasion. German telegraph traffic to occupied Oslo went through Swedish-leased cables which the Swedes intercepted. The traffic was encrypted with Germany's Geheimschreiber device, but the cypher code was broken by Swedish mathematics professor Arne Beurling
Arne Carl-August Beurling (3 February 1905 – 20 November 1986) was a Sweden, Swedish mathematician and professor of mathematics at Uppsala University (1937–1954) and later at the Institute for Advanced Study in Princeton, New Jersey. Beurling ...
[ in early summer 1940 and the results from this espionage were sent to the Allies through the Polish resistance movement in World War II, Polish resistance movement. When the German battleship Bismarck, German battleship ''Bismarck'' embarked on her voyage to attack the Atlantic convoys, Swedish intelligence informed the British of her departure from port. Swedish businessmen and diplomats were also actively spying for the Allies, in Berlin and in the occupied territories.
In 1945, as the Allies were planning to liberate Denmark and Norway, the United States wanted Sweden to co-operate in this action. Sweden began preparing for (Operation Save Denmark), in which Sweden was to invade Zealand (Denmark), Zealand from Scania. After Denmark had been liberated, Sweden was to assist the Allies in the invasion of Norway. This proved to be unnecessary, but US planes were allowed to use Swedish military bases during the liberation of Norway, from spring 1944 to 1945, and the Allies were also collaborating with the Swedish Military Intelligence and Security Service. Sweden allowed Allied spies to listen to German radio signals from a station on Öland. A radio beacon was also established in Malmö for the British military to guide bombing of Germany. Additionally, from 1943 onward, Norwegian and Danish soldiers () were trained at Swedish military bases. Sweden had also set up a series of training camps along the Norwegian border for the Norwegian resistance movement. Toward the end of the war Swedish intelligence cooperated with US air transport in relief efforts directed toward areas liberated by the Red Army.

Aftermath
The Prime Minister of the United Kingdom during World War II, Winston Churchill
Sir Winston Leonard Spencer Churchill (30 November 1874 – 24 January 1965) was a British statesman, military officer, and writer who was Prime Minister of the United Kingdom from 1940 to 1945 (Winston Churchill in the Second World War, ...
, accused Sweden of ignoring the greater moral issues and playing both sides for profit during the conflict, including its supply of steel and machine parts to Nazi Germany throughout the war. Such claims, however, use a different definition of the word "neutral" from that defined in the Hague Conventions (1899 and 1907), 1907 Hague convention, which set out the rights and duties of belligerents and neutral countries.
Forced refoulement to the Soviet Union
In January 1946, Sweden non-refoulement, forcibly transferred to the Soviet Union over 146 Baltic Waffen-SS and 2,364 German soldiers who had been interned in Swedish prison camps. At least seven of the internees committed suicide at their camp in the village of Rinkaby, rather than allow themselves to be handed over to the Soviet Union.
In 1970, film director Johan Bergenstråhle (director), Johan Bergenstråhle made a documentary, (English title: ''A Baltic Tragedy''), about the Latvian soldiers who were given to the Soviets to be sentenced to hard labor in prison camps.Baltutlamningen
