Portugal during World War II
Upon the start of World War II in 1939, the Portuguese Government announced on 1 September that the 600-year-old Anglo-Portuguese Alliance remained intact, but that since the British did not seek Portuguese assistance, Portugal was free to remain neutral in the war and would do so. In an aide-mémoire of 5 September 1939, the British Government confirmed the understanding. As Hitler's occupation swept across Europe, neutral Portugal became one of the Continent's last escape routes. Portugal managed to remain neutral throughout the war despite extraordinary pressures from both sides, notably over the strategically located Azores islands and over the wolfram (tungsten) trade.
World War II by country
Italian and German intervention had aided the Franco government in the recent Spanish Civil War, but Franco and Hitler did not achieve an agreement about Spanish participation in the new war. Galicia became an alternate source of tungsten for the Reich. Despite its non-belligerency, Spain sent volunteers to fight against the Soviet Union in the form of the Blue Division. As the Allies emerged as possible victors, the regime declared neutrality in July 1943. Removal of Spanish troops from the Eastern Front was completed in March 1944.
