Operation Weserübung's effects on Sweden

On 9 April 1940, Germany successfully launched Operation Weserübung, a military operation with the objective of simultaneously occupying Denmark and Norway and staging a coup d'état in those nations. The operation had several far-reaching consequences for Sweden, which became effectively cut off from trade with the Western world and so was more dependent on German goodwill. In turn, it eventually led to commencing the permitenttrafik and the transition of the Engelbrecht Division but also lessened the immediate risk of Sweden being a theatre of war between the Axis and the Allies.
