Cape Route
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 route was important during the Age of Sail, but became partly obsolete as the Suez Canal opened in 1869.
History
Scholars of classical antiquity disagreed whether the Atlantic was connected to the Indian Ocean. There are anecdotes about circumnavigation of Africa in ancient times; according to Herodotus, a Phoenician expedition commissioned by Egyptian king Necho II completed a voyage from the Red Sea to the Nile delta around 600 BC. Eudoxus of Cyzicus explored the West African coast, but was forced to return. Ptolemy's world map, on which the geographic knowledge of medieval Europe was founded, displays the oceans as separated from each other.
Discovery
In the late Middle Ages, the spice trade from India and the Silk Road from China were of economic importance, but the 1453 fall of Constantinople disrupted trade, and gave the Europeans incentives to find a sea route. Portuguese explorer Diogo Cão explored the African coast south to present-day Namibia, and Bartolomeu Dias found the Cape of Good Hope in 1488. Vasco da Gama led an exhibition which led to the Portuguese discovery of the sea route to India in 1498, and a series of expeditions known as the Carreira da Índia. Since then, the Cape Route has been in use.
Christopher Columbus sought to find a sea route through India westwards, but instead found the way to the Americas. These expeditions marked the beginning of the Age of Discovery, in which European explorers charted the world's oceans.
Use during Age of Sail
The Cape Route was used by European East India Companies. In the 17th century, Caribbean pirates followed the Pirate Round; a parallel route from the Caribbean across the south Atlantic, to the Indian Ocean.
The European colonization of Africa was before the late 19th century mostly limited to a few coastal outposts, to support the Cape Route. The Dutch East India Company founded the Dutch Cape Colony as a layover port on the way to the Dutch East Indies.
The Brouwer Route was an extension of the Cape Route across the Indian Ocean to Indonesia. The Clipper Route is a route along the Roaring Forties between Europe and Australia.
Suez Canal
The Suez Canal opened in 1869, allowing a shortcut between the Atlantic and the Indian Ocean. Because of the prevailing winds at Suez, the canal is less suitable for sailing boats, so steamships got a competitive advantage when the canal opened. While the Cape Route remained useful for clippers for some decades, the opening of the canal was the beginning of the end of the Cape Route, as well as the Age of Sail as a whole.
The route has however been relevant as a secondary route if the Suez Canal were to be disrupted, as well as in yacht racing.
The maximum ship size for the Suez Canal are referred to as Suezmax. Capesize ships are those too large for the Suez Canal, which need to use the Cape Route between the Atlantic and the Indian Ocean. The 2015 inauguration of the New Suez Canal raised the Suezmax dimensions, and allowed larger ships. Thereby, the Cape Route became even less important.
