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.
Treaty of Versailles
Portugal entered the war on the Allied side in 1916 primarily to ensure the security of its African colonies, which were threatened with seizure by both Britain and Germany. To this extent, she succeeded in her war aims. The treaty recognized Portuguese sovereignty over these areas and awarded her small portions of Germany's bordering overseas colonies. Otherwise, Portugal gained little at the peace conference. Her promised share of German reparations never materialized, and a seat she coveted on the executive council of the new League of Nations went instead to Spain—which had remained neutral in the war. In the end, Portugal ratified the treaty, but got little out of the war, which cost more than 8,000 Portuguese troops and as many as 100,000 of her African colonial subjects their lives.
