Question: What leader sponsored the expedition discovering the country having Barlavento Islands?

full_context: Document 1: Spice trade: The first country to attempt to circumnavigate Africa was Portugal, which had, since the early 15th century, begun to explore northern Africa under Henry the Navigator. Emboldened by these early successes and eyeing a lucrative monopoly on a possible sea route to the Indies the Portuguese first crossed the Cape of Good Hope in 1488 on an expedition led by Bartolomeu Dias. Just nine years later in 1497 on the orders of Manuel I of Portugal, four vessels under the command of navigator Vasco da Gama rounded the Cape of Good Hope, continuing to the eastern coast of Africa to Malindi to sail across the Indian Ocean to Calicut, on the Malabar Coast. in south India -- the capital of the local Zamorin rulers. The wealth of the Indies was now open for the Europeans to explore; the Portuguese Empire was the earliest European seaborne empire to grow from the spice trade.

Document 3: Portugal: Portugal spearheaded European exploration of the world and the Age of Discovery. Prince Henry the Navigator, son of King João I, became the main sponsor and patron of this endeavour. During this period, Portugal explored the Atlantic Ocean, discovering several Atlantic archipelagos like the Azores, Madeira, and Cape Verde, explored the African coast, colonized selected areas of Africa, discovered an eastern route to India via the Cape of Good Hope, discovered Brazil, explored the Indian Ocean, established trading routes throughout most of southern Asia, and sent the first direct European maritime trade and diplomatic missions to China and Japan.
Document 4: Portuguese discoveries: Portuguese discoveries (Portuguese: Descobrimentos portugueses) are the numerous territories and maritime routes discovered by the Portuguese as a result of their intensive maritime exploration during the 15th and 16th centuries. Portuguese sailors were at the vanguard of European overseas exploration, discovering and mapping the coasts of Africa, Canada, Asia and Brazil, in what became known as the Age of Discovery. Methodical expeditions started in 1419 along West Africa's coast under the sponsorship of prince Henry the Navigator, with Bartolomeu Dias reaching the Cape of Good Hope and entering the Indian Ocean in 1488. Ten years later, in 1498, Vasco da Gama led the first fleet around Africa to India, arriving in Calicut and starting a maritime route from Portugal to India. Portuguese explorations then proceeded to southeast Asia, where they reached Japan in 1542, forty - four years after their first arrival in India. In 1500, the Portuguese nobleman Pedro Álvares Cabral became the first European to discover Brazil.
Document 5: Age of Discovery: Portugal's neighbouring fellow Iberian rival, Castile, had begun to establish its rule over the Canary Islands, located off the west African coast, in 1402, but then became distracted by internal Iberian politics and the repelling of Islamic invasion attempts and raids through most of the 15th century. Only late in the century, following the unification of the crowns of Castile and Aragon and the completion of the reconquista, did an emerging modern Spain become fully committed to the search for new trade routes overseas. The Crown of Aragon had been an important maritime potentate in the Mediterranean, controlling territories in eastern Spain, southwestern France, major islands like Sicily, Malta, and the Kingdom of Naples and Sardinia, with mainland possessions as far as Greece. In 1492 the joint rulers conquered the Moorish kingdom of Granada, which had been providing Castile with African goods through tribute, and decided to fund Christopher Columbus's expedition in the hope of bypassing Portugal's monopoly on west African sea routes, to reach ``the Indies ''(east and south Asia) by travelling west. Twice before, in 1485 and 1488, Columbus had presented the project to king John II of Portugal, who rejected it.
Document 6: Late Middle Ages: The 1469 marriage of Isabella I of Castile and Ferdinand II of Aragon and the 1479 death of John II of Aragon led to the creation of modern-day Spain. In 1492, Granada was captured from the Moors, thereby completing the Reconquista. Portugal had during the 15th century – particularly under Henry the Navigator – gradually explored the coast of Africa, and in 1498, Vasco da Gama found the sea route to India. The Spanish monarchs met the Portuguese challenge by financing the expedition of Christopher Columbus to find a western sea route to India, leading to the discovery of the Americas in 1492.
Document 7: Preguiça, São Nicolau: Preguiça is a settlement in the central part of the island of São Nicolau, Cape Verde. It is situated on the south coast, 6 km south of Ribeira Brava. It served as the port of Ribeira Brava, after the older "Porto de Lapa", 6 km to the northeast, had been abandoned in 1653 due to pirate attacks.
Document 8: São Nicolau, Cape Verde: São Nicolau (Portuguese meaning Saint Nicholas) is one of the Barlavento (Windward) islands of Cape Verde. It is located between the islands of Santa Luzia and Sal. Its population is 12,424 (2015), with an area of 343 km². The main towns are Ribeira Brava and Tarrafal de São Nicolau.
Document 9: Brava, Cape Verde: Brava (Portuguese for “wild” or "brave") is an island in Cape Verde, in the Sotavento group. At , it is the smallest inhabited island of the Cape Verde archipelago, but at the same time the greenest. First settled in the early 16th century, its population grew after Mount Fogo on neighbouring Fogo erupted in 1680. For more than a century, its main industry was whaling, but the island economy is now primarily agricultural.
Document 10: Monte Gordo, Cape Verde: Monte Gordo is a mountain on the island of São Nicolau, Cape Verde. At 1,312 m elevation, it is the island's highest point.

The boundary of the municipalities Tarrafal de São Nicolau and Ribeira Brava runs over the mountain. It is part of the "Monte Gordo Natural Park".
Document 11: Age of Discovery: Global exploration started with the Portuguese discoveries of the Atlantic archipelagos of Madeira and the Azores, the coast of Africa, and the discovery of the sea route to India in 1498; and the Crown of Castile (Spain) the trans - Atlantic Voyages of Christopher Columbus to the Americas between 1492 and 1502 and the first circumnavigation of the globe in 1519 -- 1522. These discoveries led to numerous naval expeditions across the Atlantic, Indian and Pacific oceans, and land expeditions in the Americas, Asia, Africa and Australia that continued into the late 19th century, and ended with the exploration of the polar regions in the 20th century.
Document 12: Carvoeiros: Carvoeiros is a settlement in the northern part of the island of São Nicolau, Cape Verde. It is situated on the north coast, 2 km east of Queimadas and 4 km north of Ribeira Brava.
Document 13: European exploration of Africa: European exploration of Sub-Saharan Africa begins with the Age of Discovery in the 15th century, pioneered by Portugal under Henry the Navigator. The Cape of Good Hope was first reached by Bartolomeu Dias on 12 March 1488, opening the important sea route to India and the Far East, but European exploration of Africa itself remained very limited during the 16th and 17th centuries. The European powers were content to establish trading posts along the coast while they were actively exploring and colonizing the New World. Exploration of the interior of Africa was thus mostly left to the Arab slave traders, who in tandem with the Muslim conquest of the Sudan established far - reaching networks and supported the economy of a number of Sahelian kingdoms during the 15th to 18th centuries.
Document 14: Carriçal: Carriçal is a settlement in the eastern part of the island of São Nicolau, Cape Verde. It is situated on the south coast, 8 km southeast of Juncalinho and 24 km east of Ribeira Brava. It is the easternmost settlement on the island. Some 8 km east is the island's easternmost point, Ponta Leste. The place was mentioned as "Currissal" in the 1747 map by Jacques-Nicolas Bellin.
Document 15: Middle Ages: In the early 15th century, the countries of the Iberian peninsula began to sponsor exploration beyond the boundaries of Europe. Prince Henry the Navigator of Portugal (d. 1460) sent expeditions that discovered the Canary Islands, the Azores, and Cape Verde during his lifetime. After his death, exploration continued; Bartolomeu Dias (d. 1500) went around the Cape of Good Hope in 1486 and Vasco da Gama (d. 1524) sailed around Africa to India in 1498. The combined Spanish monarchies of Castile and Aragon sponsored the voyage of exploration by Christopher Columbus (d. 1506) in 1492 that discovered the Americas. The English crown under Henry VII sponsored the voyage of John Cabot (d. 1498) in 1497, which landed on Cape Breton Island.
