RadhaniteThe Radhanites or Radanites (רדהנים; ar-Raðaniyya) were early medieval Jewish merchants, active in the trade between Christendom and the Muslim world during roughly the 8th to the 10th centuries. Many trade routes previously established under the Roman Empire continued to function during that period, largely through their efforts. Their trade network covered much of Europe, North Africa, the Middle East, Central Asia, and parts of India and China.
Siege of LisbonThe siege of Lisbon, from 1 July to 25 October 1147, was the military action against the Muslim-ruled Taifa of Badajoz that brought the city of Lisbon under the definitive control of the new Christian power, the Kingdom of Portugal. The siege of Lisbon was one of the few Christian victories of the Second Crusade—it was "the only success of the universal operation undertaken by the pilgrim army", i.e., the Second Crusade, according to the near contemporary historian Helmold, although others have questioned whether it was really part of that crusade.
Winds in the Age of SailThe captain of a steam ship naturally chooses the shortest route to nearby destinations. Since a sailing ship is usually pushed by winds and currents, its captain must find a route where the wind will probably blow in the right direction. Tacking, i.e. using contrary wind to pull (sic) the sails, was always possible but wasted time because of the zigzagging required, and this would significantly delay long voyages. The early European explorers were not only looking for new lands.
World mapA world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the earth. While this is true of any map, these distortions reach extremes in a world map. Many techniques have been developed to present world maps that address diverse technical and aesthetic goals. Charting a world map requires global knowledge of the earth, its oceans, and its continents.
AntilliaAntillia (or Antilia) is a phantom island that was reputed, during the 15th-century age of exploration, to lie in the Atlantic Ocean, far to the west of Portugal and Spain. The island also went by the name of Isle of Seven Cities (Ilha das Sete Cidades in Portuguese, Isla de las Siete Ciudades in Spanish). It originates from an old Iberian legend, set during the Muslim conquest of Hispania 714.
BuruBuru (formerly spelled Boeroe, Boro, or Bouru) is the third largest island within the Maluku Islands of Indonesia. It lies between the Banda Sea to the south and Seram Sea to the north, west of Ambon and Seram islands. The island belongs to Maluku province and includes the Buru and South Buru regencies. Their administrative centers, Namlea and Namrole, respectively, have ports and are the largest towns of the island, served by Namlea Airport and Namrole Airport respectively.
Discovery doctrineThe discovery doctrine, or doctrine of discovery, is a disputed interpretation of international law during the Age of Discovery, introduced into United States municipal law by the US Supreme Court Justice John Marshall in Johnson v. McIntosh (1823). In Marshall's formulation of the doctrine, discovery of territory previously unknown to Europeans gave the discovering nation title to that territory against all other European nations, and this title could be perfected by possession.
ElminaElmina, also known as Edina by the local Fante, is a town and the capital of the Komenda/Edina/Eguafo/Abirem District on the south coast of Ghana in the Central Region, situated on a bay on the Atlantic Ocean, west of Cape Coast. Elmina was the first European settlement in West Africa and it has a population of 33,576 people. History of Elmina Prior to the arrival of the Portuguese, the town was called Anomansah ("perpetual" or "inexhaustible drink") from its position on the peninsula between the Benya lagoon and the sea.
Chinese explorationChinese exploration includes exploratory Chinese travels abroad, on land and by sea, from the travels of Han dynasty diplomat Zhang Qian into Central Asia during the 2nd century BC until the Ming dynasty treasure voyages of the 15th century that crossed the Indian Ocean and reached as far as East Africa. The Western Han envoy Zhang Qian traveled beyond the Tarim Basin in the 2nd century BC, introducing the Chinese to the kingdoms of Central Asia, Hellenized Persia, India, and the Middle East in search of allies against the Xiongnu.
First contact (anthropology)In anthropology, first contact is the first meeting of two communities previously without contact with one another. Notable examples of first contact are those between the Spanish Empire and the Arawak in 1492; and the Aboriginal Australians with Europeans in 1788 when the First Fleet arrived in Sydney. Such contact is sometimes described as a "discovery", such as the British and United States did by creating the legal theory of the "Doctrine of Discovery".
