Dom Henrique of Portugal, Duke of Viseu, better known as Prince Henry the Navigator, was a central figure in the early days of the Portuguese Empire and in the 15th-century European maritime discoveries and maritime expansion. Through his administrative direction, he is regarded as the main initiator of what would be known as the Age of Discovery. Henry was the fourth child of King John I of Portugal, who founded the House of Aviz.
The history of the Kingdom of Portugal from the Illustrious Generation of the early 15th century to the fall of the House of Aviz in the late 16th century has been named the "Portuguese golden age" and the "Portuguese Renaissance". During this period, Portugal was the first European power to begin building a colonial empire as during the Age of Exploration Portuguese sailors and explorers discovered an eastern route to India as well as several Atlantic archipelagos and colonized the African coast and Brazil. They also explored the Indian Ocean and established trading routes throughout most of southern Asia, sending the first direct European maritime trade and diplomatic missions to Ming China and to Japan, at the same time installing trading posts and the most important colony: Portuguese Macau. The Portuguese Renaissance produced a plethora of poets, historians, critics, theologians, and moralists. The Cancioneiro Geral by Garcia de Resende is taken to mark the transition from Old Portuguese to the modern Portuguese language.
D. Vasco da Gama, 1st Count of Vidigueira, was a Portuguese explorer and nobleman who was the first European to reach India by sea.
An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences. Depth contours, shoreline configurations, and interactions with other currents influence a current's direction and strength. Ocean currents are primarily horizontal water movements.
The Roaring Forties are strong westerly winds that occur in the Southern Hemisphere, generally between the latitudes of 40° and 50° south. The strong eastward air currents are caused by the combination of air being displaced from the Equator towards the South Pole, Earth's rotation, and the scarcity of landmasses to serve as windbreaks at those latitudes.
The spice trade involved historical civilizations in Asia, Northeast Africa and Europe. Spices, such as cinnamon, cassia, cardamom, ginger, pepper, nutmeg, star anise, clove, and turmeric, were known and used in antiquity and traded in the Eastern World. These spices found their way into the Near East before the beginning of the Christian era, with fantastic tales hiding their true sources.
The trade winds or easterlies are permanent east-to-west prevailing winds that flow in the Earth's equatorial region. The trade winds blow mainly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere, strengthening during the winter and when the Arctic oscillation is in its warm phase. Trade winds have been used by captains of sailing ships to cross the world's oceans for centuries. They enabled European colonization of the Americas, and trade routes to become established across the Atlantic Ocean and the Pacific Ocean.
The Age of Discovery, also known as the Age of Exploration, was part of the early modern period and largely overlapping with the Age of Sail. It was a period from approximately the late 15th century to the 17th century, during which seafarers from a number of European countries explored, colonized, and conquered regions across the globe. The Age of Discovery was a transformative period in world history when previously isolated parts of the world became connected to form the world system and laid the groundwork for globalization. The extensive overseas exploration, particularly the opening of maritime routes to the Indies and the European colonization of the Americas by the Spanish and Portuguese, later joined by the English, French and Dutch, spurred in the International global trade. The interconnected global economy of the 21st century has its origins in the expansion of trade networks during this era.
A sea lane, sea road or shipping lane is a regularly used navigable route for large water vessels (ships) on wide waterways such as oceans and large lakes, and is preferably safe, direct and economic. During the Age of Sail, they were determined by the distribution of land masses but also by the prevailing winds, whose discovery was crucial for the success of long maritime voyages. Sea lanes are very important for seaborne trade.
The Loaísa expedition was an early 16th-century Spanish voyage of discovery to the Pacific Ocean, commanded by García Jofre de Loaísa and ordered by King Charles I of Spain to colonize the Spice Islands in the East Indies. The seven-ship fleet sailed from La Coruña, Spain in July 1525 and became the second naval expedition in history to cross the Pacific Ocean, after the Magellan-Elcano circumnavigation. The expedition resulted in the discovery of the Sea of Hoces south of Cape Horn, and the Marshall Islands in the Pacific. One ship ultimately arrived in the Spice Islands in September 1526.
Volta do mar, volta do mar largo, or volta do largo is a navigational technique perfected by Portuguese navigators during the Age of Discovery in the late fifteenth century, using the dependable phenomenon of the great permanent wind circle, the North Atlantic Gyre. This was a major step in the history of navigation, when an understanding of winds in the age of sail was crucial to success: the European sea empires would not have been established without an understanding of the trade winds.
The clipper route was derived from the Brouwer Route and was sailed by clipper ships between Europe and the Far East, Australia and New Zealand. The route, devised by the Dutch navigator Hendrik Brouwer in 1611, reduced the time of a voyage between The Netherlands and Java, in the Dutch East Indies, from almost 12 months to about six months, compared to the previous Arab and Portuguese monsoon route.
Cape Horn is the southernmost headland of the Tierra del Fuego archipelago of southern Chile, and is located on the small Hornos Island. Although not the most southerly point of South America, Cape Horn marks the northern boundary of the Drake Passage and marks where the Atlantic and Pacific Oceans meet.
The Brouwer Route was a 17th-century route used by ships sailing from the Cape of Good Hope to the Dutch East Indies, as the eastern leg of the Cape Route. The route took ships south from the Cape into the Roaring Forties, then east across the Indian Ocean, before turning northeast for Java. Thus it took advantage of the strong westerly winds for which the Roaring Forties are named, greatly increasing travel speed.
Portuguese maritime exploration resulted in the numerous territories and maritime routes recorded by the Portuguese as a result of their intensive maritime journeys during the 15th and 16th centuries. Portuguese sailors were at the vanguard of European exploration, chronicling and mapping the coasts of Africa and Asia, then known as the East Indies, and Canada and Brazil, in what came to be known as the Age of Discovery.
The Portuguese Indian Armadas were the fleets of ships funded by the Crown of Portugal, and dispatched on an annual basis from Portugal to India. The principal destination was Goa, and previously Cochin. These armadas undertook the Carreira da Índia from Portugal, following the maritime discovery of the Cape route, to the Indian subcontinent by Vasco da Gama in 1497–99.
Early Polynesian explorers reached nearly all Pacific islands by 1200 CE, followed by Asian navigation in Southeast Asia and the West Pacific. During the Middle Ages, Muslim traders linked the Middle East and East Africa to the Asian Pacific coasts, reaching southern China and much of the Malay Archipelago. Direct European contact with the Pacific began in 1512, with the Portuguese encountering its western edges, soon followed by the Spanish arriving from the American coast.
The European-Asian sea route, commonly known as the sea route to India or the Cape Route, is a shipping route from the European coast of the Atlantic Ocean to Asia's coast of the Indian Ocean passing by the Cape of Good Hope and Cape Agulhas at the southern edge of Africa. The first recorded completion of the route was made in 1498 by Portuguese explorer Vasco da Gama, the admiral of the first Portuguese Armadas bound eastwards to make the discovery. The route was important during the Age of Sail, but became partly obsolete as the Suez Canal opened in 1869.
Portuguese nautical science evolved from the successive expeditions and experience of the Portuguese pilots. It led to a fairly rapid evolution, creating an elite of astronomers, navigators, mathematicians and cartographers. Among them stood Pedro Nunes with studies on how to determine latitude by the stars, and João de Castro, who made important observations of magnetic declination over the entire route around Africa.
