The Azores are an archipelago of nine volcanic islands situated in the North Atlantic Ocean, approximately 1,400 km west of the Portuguese mainland. They are the westernmost territory of Portugal and lie at the tectonic junction of the North American, Eurasian, and African plates.
Mount Pico on the island of Pico is the highest point in both the Azores and all of Portugal, reaching 2,351 metres. Measured from the ocean floor to its summit, it is among the tallest mountains on the planet.
Settlement of the Azores began formally in 1439, with migrants drawn mainly from the Portuguese mainland provinces of Algarve and Alentejo. The early population also included Flemings, Sephardic Jews, Moors, Italians, Spaniards, and Africans from Guinea, Cape Verde, and São Tomé and Príncipe.
Prince Henry the Navigator arranged the Flemish settlement after his sister Isabel, married to Philip the Good, Duke of Burgundy, appealed to him to accept displaced Flemings fleeing revolt and famine in Flanders. Henry granted permission and supplied the settlers with transport and provisions. By 1490 there were an estimated 2,000 Flemings living across the islands.
In 1943 Portuguese ruler António de Oliveira Salazar leased air and naval bases in the Azores to Great Britain. The British occupation, codenamed Operation Alacrity, began in October 1943 and was a key turning point in the Battle of the Atlantic. It enabled Royal Air Force, U.S. Army Air Forces, and U.S. Navy aircraft to close the Mid-Atlantic surveillance gap, protecting convoys and hunting German U-boats.
An estimated 58,000 Azorean Portuguese were transported to the United States by the Dominion Line and White Star Line ships between 1902 and 1921 alone. From 1921 to 1977, roughly 250,000 Azoreans immigrated to Rhode Island and Massachusetts, which remain the primary destinations. Many later settled in Northern California, particularly in Turlock and the San Joaquin Valley.
