Content:  São Jorge da Mina castle is built in the coast of Western Africa, by Diogo de Azambuja, becoming one of the most important Portuguese naval bases. This structure exists to this day and is a robust example of slave trade in this era. History of Elmina Castle and the Dutch and Portuguese navies would be enlightening. In 1488, Bartolomeu Dias became the first European to sail around the southernmost tip of Africa, the Cape of Good Hope. João Vaz Corte-Real arrived at Newfoundland in 1473. Part of the coast of Newfoundland was charted by the Corte-Real brothers, sons of João Vaz Corte-Real, in a failed 
Title: Bartolomeu Dias
Content:  Bartolomeu Dias (c. 1450 – 29 May 1500) was a Portuguese mariner and explorer. In 1488, he became the first European navigator to round the southern tip of Africa and to demonstrate that the most effective southward route for ships lay in the open ocean, well to west of the African coast. His discoveries effectively established the sea route between Europe and Asia.

In 1482 the Congo River was explored by Diogo Cão, who in 1486 continued to Cape Cross (modern Namibia). The next crucial breakthrough was in 1488, when Bartolomeu Dias rounded the southern tip of Africa, which he named "Cape of Storms" (Cabo das Tormentas), anchoring at Mossel Bay and then sailing east as far as the mouth of the Great Fish River, proving that the Indian Ocean was accessible from the Atlantic. Simultaneously Pêro da Covilhã, sent out travelling secretly overland, had reached Ethiopia having collected important information about

In 1652, a victualling station was established at the Cape of Good Hope by Jan van Riebeeck on behalf of the Dutch East India Company. For most of the 17th and 18th centuries, the slowly expanding settlement was a Dutch possession. In 1795, the Dutch colony was captured by the British during the French Revolutionary Wars. The British intended to use Cape Town as a major port on the route to Australia and India. 
Title: Prince Henry the Navigator
Content:  Until Henry's time, Cape Bojador remained the most southerly point known to Europeans on the desert coast of Africa. Superstitious seafarers held that beyond the cape lay sea monsters and the edge of the world. In 1434, Gil Eanes, the commander of one of Henry's expeditions, became the first European known to pass Cape Bojador.  Using the new ship type, the expeditions then pushed onwards. Nuno Tristão and Antão Gonçalves reached Cape Blanco in 1441. The Portuguese sighted the Bay of Arguin in 1443 and built an important slave fort on the island of Arguin around the year 1448. Dinis Dias soon came across the Senegal River and rounded the peninsula of Cap-Vert in 
Title: History of Goa
Content:  Vasco da Gama commanded the first circumnavigation of Africa, relying on stories and maps from earlier Portuguese voyages. His fleet of four ships set off from Lisbon in 1497. After island stops at Tenerife and Cape Verde, the ships made landfall on the West African coast. They then steered southwest into the vast South Atlantic Ocean. Near Brazil, by making an eastward turn, they headed toward the southern cape of Africa which they rounded. After passing by the Rio do Infante described earlier by a fellow explorer, a northward course was set. The ships stopped at the East African ports of Mozambique, Mombasa and Malindi. An Arab pilot, or an Indian,

Antonio de Noli, who became the first governor of Cape Verde (and the first European colonial governor in Sub-Saharan Africa), is also considered the discoverer of the First Islands of Cape Verde. Along the western and eastern coasts of Africa, progress was also steady; Portuguese sailors reached Cape Bojador in 1434 and Cape Blanco in 1441. In 1443, they built a fortress on the island of Arguin, in modern-day Mauritania, trading

Explorers of routes from Europe towards Asia, the Indian Ocean, and the Pacific Ocean, include Vasco da Gama (1460–1524), a navigator who made the first trip from Europe to India and back by the Cape of Good Hope, discovering the ocean route to the East; Pedro Álvares Cabral (c. 1467/1468 – c. 1520) who, following the path of Vasco da Gama, claimed Brazil and led the first expedition that

On the second voyage, in 1456, Cadamosto became the first European to reach the Cape Verde Islands. António Noli later claimed the credit. By 1462, the Portuguese had explored the coast of Africa as far as present-day Sierra Leone. Twenty-eight years later, Bartolomeu Dias proved that Africa could be circumnavigated when he reached the southern tip of the continent, now known as the Cape of Good Hope. In 1498, Vasco da Gama became the first European sailor to reach India by sea.
Title: History of South Africa
Content:  The Portuguese mariner Bartolomeu Dias was the first European to explore the coastline of South Africa in 1488, while attempting to discover a trade route to the Far East via the southernmost cape of South Africa, which he named Cabo das Tormentas, meaning Cape of Storms. In November 1497, a fleet of Portuguese ships under the command of the Portuguese mariner Vasco da Gama rounded the Cape of Good Hope. By 16 December, the fleet had passed the Great Fish River on the east coast of South Africa, where Dias had earlier turned back. Da Gama gave the name Natal to the coast he was passing, which in Portuguese means Christmas. Da Gama's fleet proceeded northwards to Zanzibar and later sailed eastwards, eventually reaching India and opening the Cape Route between Europe and Asia.
