The Azores, officially the Autonomous Region of the Azores, is one of the two autonomous regions of Portugal. It is an archipelago composed of nine volcanic islands in the Macaronesia region of the North Atlantic Ocean, about 1,400 km (870 mi) west of Lisbon, about 1,500 km (930 mi) northwest of Morocco, and about 1,930 km (1,200 mi) southeast of Newfoundland, Canada.
Gaspar Frutuoso wrote Saudades da Terra, the first history of the Azores and Macaronesia, in the 1580s.
Under the direction of Prince Henry the Navigator, the Azores were discovered and populated in the early 1400s.
