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.
Puerto Ricans in World War II
Before the United States entered World War II Puerto Ricans were already fighting on European soil in the Spanish Civil War. The Spanish Civil War was a major conflict in Spain that started following an attempted "coup d'état" committed by parts of the army, led by the Nationalist General Francisco Franco, against the government of the Second Spanish Republic. Puerto Ricans fought on behalf of both of the factions involved, the "Nationalists" as members of the Spanish Army and the "Loyalists" (Republicans) as members of the Abraham Lincoln International Brigade.
