But even these reforms were seen as far too radical by some conservatives. Those on the right wing wanted strong leaders 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 Ådalen shootings

Apart from a period termed "the vacation government" (Sw: semesterregeringen) between June 19 and September 28, 1936, Per Albin Hansson was to be the Prime Minister of Sweden until his death in 1946.

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

 and most of Sweden's political energy in the international arena had been directed towards the preservation of the League of Nations.

The Swedish non-aligned policy during this period was founded on the assumption that there were two opposing powers in the Baltic, Germany and the Soviet Union; Because these two powers needed to guard against each other, the hope was that they would only ever be able to deploy minor forces against Sweden or other non-aligned countries. It was this expectation which made the defense of a small country feasible. The Molotov-Ribbentrop Pact

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.

Defense of Finland

When the Soviet Union invaded Finland in November 1939, many Swedes favored some sort of involvement in the conflict, both on a humanitarian and on a military basis. Sweden's interest in Finland lay in the fact that Finland had been an integrated part of Sweden for more than six hundred years, with Sweden losing control of its eastern provinces in 1809. Despite several pleas from the Finnish government, the Swedish government declined to engage militarily with the Red Army

Realizing this danger, however, and the consequent possibility of Allied or German occupation and of the war being waged on their territory, both the Swedes and the Norwegians refused to allow this proposal.

Meanwhile, the Germans having suspected an Allied threat, were making their own plans for an invasion of Norway in order to protect their strategic supply lines. The Altmark Incident

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 March 12, 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. However, Finland sued for peace on March 12, so this plan had to be abandoned as well. 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. April 9 was set as the date of Operation Weserübung

 and the Allies.

When Germany invaded both Denmark and Norway on April 9, 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 defense 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. Sweden also started to build fortifications at the Norwegian border and along the coast of Scania.

During its invasion of Norway, Germany demanded access to the Swedish telephone and telegraph lines between Germany and Norway. Sweden allowed this, but tapped the lines. In the early summer of that year (1940) the Swedish mathematician Arne Beurling

. 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.

 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 War 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."

, reaching ten million tons per year. The Swedish neutrality policy meant that the government could not interfere with the trade. 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. This is a contentious view that has been debated in the aftermath of the war. Sir Ralph Glyn

, claimed that a cessation of Swedish iron ore exports would bring the war to an end within six months.

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

. 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 10,000; Denmark 6,000; France 11,000; Netherlands 20,000). Many more joined the Allies, which was also contrary to government policy.

Sweden made efforts to help the Allied Forces.

 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 Rädda Danmark" (Operation Save Denmark), in which Sweden was to invade Zealand from Scania. After Denmark had been liberated, Sweden was to assist the Allies in the invasion of Norway. This proved not to be necessary, 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, however, had signed it and its Government was determined to follow it, to avoid any criticism of not being ”neutral”.
