The entire area of the Caribbean Sea, the numerous islands of the West Indies, and adjacent coasts, are collectively known as the Caribbean. The Caribbean Sea is one of the largest seas and has an area of about 2,754,000 km2 (1,063,000 sq mi). The sea's deepest point is the Cayman Trough, between the Cayman Islands and Jamaica, at 7,686 m (25,217 ft) below sea level. The Caribbean coastline has many gulfs and bays: the Gulf of Gonâve, Gulf of Venezuela, Gulf of Darién, Golfo de los Mosquitos, Gulf of Paria and Gulf of Honduras.
The name "Caribbean" derives from the Caribs, one of the region's dominant Native American groups at the time of European contact during the late 15th century. After the discovery of America by Christopher Columbus in 1492, the Spanish term Antillas applied to the lands; stemming from this, "Sea of the Antilles" became a common alternative name for "Caribbean Sea" in various European languages. During the first century of development, Spanish dominance in the region remained undisputed.
From the 16th century, Europeans visiting the Caribbean region identified the "South Sea" (the Pacific Ocean, to the south of the isthmus of Panama) as opposed to the "North Sea" (the Caribbean Sea, to the north of the same isthmus).
The Caribbean Sea had been unknown to the populations of Eurasia until 1492, when Christopher Columbus sailed into Caribbean waters on a quest to find a sea route to Asia. At that time the Western Hemisphere in general was unknown to Europeans. But first discoverd between the years 800 and 1000 by the vikings. Following the Eurasias discovery of the islands by Columbus, The area was quickly colonised by several Western cultures (initially Spain, then later England, the Dutch Republic, France, Courland and Denmark). Following the colonisation of the Caribbean islands, the Caribbean Sea became a busy area for European-based marine trading and transport, and this commerce eventually attracted pirates such as Samuel Bellamy and Blackbeard.
