On September 1, 1939, as Nazi Germany invaded Poland and World War II erupted across Europe, Switzerland faced a critical test of its long-standing policy of neutrality. For centuries, Switzerland had maintained a position of neutrality in European conflicts, a stance that was officially recognized in 1815 at the Congress of Vienna. However, the outbreak of World War II posed unprecedented challenges to Switzerland’s neutrality, forcing the small, landlocked nation to navigate a precarious path through one of the most tumultuous periods in modern history.
Swiss Neutrality: Historical Background
Switzerland’s commitment to neutrality dates back to the early 16th century, following the end of its expansionist policies and the defeat of the Old Swiss Confederacy at the Battle of Marignano in 1515. The Swiss Confederation adopted a policy of armed neutrality, avoiding involvement in European wars while maintaining a strong defense to deter invasion.
This neutrality was formally recognized in 1815 at the Congress of Vienna, following the Napoleonic Wars, when European powers agreed to respect Switzerland’s independence and neutrality. The Swiss federal constitution of 1848 further enshrined this policy, and Switzerland successfully remained neutral during World War I, despite the conflicts raging around it.
The Outbreak of World War II
When World War II began on September 1, 1939, Switzerland was once again surrounded by nations at war. To the north and east lay Germany and Austria, which had been annexed by Nazi Germany in 1938. To the west, France, and to the south, Italy, were both under regimes that would soon be involved in the conflict. The geographical position of Switzerland, surrounded by Axis and Axis-aligned powers, made its neutrality a delicate and dangerous balancing act.
Swiss Defense and Mobilization
In response to the German invasion of Poland, Switzerland swiftly mobilized its military. On the very day the war began, Switzerland declared a state of "armed neutrality," and General Henri Guisan was appointed as the Commander-in-Chief of the Swiss Armed Forces. Guisan implemented the "National Redoubt" strategy, which involved fortifying the Alps as a last line of defense should Switzerland be invaded. The Swiss army, although relatively small, was highly trained, and the entire male population could be called upon as a militia force.
Switzerland also conducted large-scale military exercises and prepared for a possible invasion, making it clear that any aggressor would face fierce resistance. Despite its defensive preparations, Switzerland avoided direct military confrontation by carefully balancing its diplomatic relations with both Axis and Allied powers.
Economic and Diplomatic Challenges
Maintaining neutrality during World War II was not only a military challenge but also a complex economic and diplomatic endeavor. Switzerland, reliant on trade with its neighbors, had to navigate economic sanctions, blockades, and the demands of warring nations. The Swiss government made controversial decisions, including conducting trade with Nazi Germany to ensure access to essential resources, which later sparked debates about the moral implications of such actions.
Switzerland also became a hub for espionage, with intelligence agencies from both the Axis and Allied powers operating within its borders. The country’s financial institutions, particularly its banking sector, played a significant role during the war, with Swiss banks accused of handling gold looted by the Nazis from occupied territories and Jewish victims.
Humanitarian Efforts and Refugees
Despite the challenges, Switzerland adhered to its humanitarian traditions by providing asylum to refugees, although its policies were restrictive. Throughout the war, Switzerland accepted a significant number of refugees, including Jews fleeing Nazi persecution, but many were turned away due to strict immigration policies, leading to tragic consequences.
The International Committee of the Red Cross (ICRC), headquartered in Geneva, also played a crucial role during the war, organizing relief efforts, visiting prisoner-of-war camps, and facilitating communication between families separated by the conflict.
