Denmark's withdrawal from the League of Nations marked a significant shift in the nation's approach to international diplomacy during a turbulent period. Following the invasion and occupation of Denmark by Nazi Germany in April 1940, the Danish government found itself navigating complex international dynamics as World War II unfolded. The League, which was formed in 1920 to promote peace and cooperation among nations following World War I, was increasingly seen as ineffective, particularly in the face of aggression by totalitarian regimes. Denmark's decision to leave was influenced by feelings of futility regarding the League's capacity to safeguard its sovereignty and territorial integrity.

The formal announcement of Denmark's departure took place amidst widespread instability across Europe, where many nations were reassessing their engagement with the League. By July 1940, it became apparent that the League could not provide the security Denmark required, especially with German forces exercising control over its territory. The Danish government's choice to align more closely with its national interests was reflective of a broader trend, as multiple countries reevaluated their commitments to international agreements at a time of existential threat. This decision signified Denmark's shift towards pragmatism in foreign policy amidst existential threats and the realities of military occupation.

Ultimately, Denmark's exit from the League of Nations illustrated how individual countries prioritized their sovereignty and national interests over collective agreements during one of history's most challenging eras. This move not only affected Denmark's future diplomatic interactions but also set a precedent for other nations facing similar threats; it highlighted the limitations of international organizations when member nations are under direct assault.
