The Guianas

The Guianas (; ; ) are a region in northeastern South America along the Atlantic coast, divided in several territories and independent countries.

Geography 
The Guianas are on the Guiana Shield, a Precambrian geological formation that is limited to the south and to the east by Brazil, to the west by Venezuela and to the north by the Atlantic Ocean.

The Guianas includes the following three territories, from west to east:
 Guyana, an independent country;
 Suriname, also an independent country; and
 French Guiana, an overseas department of France.

Two other territories are sometimes added:
 The Guayana Region, formerly the Guayana Province, in southeast Venezuela (Spanish Guyana)
 Portuguese Guiana (Brazilian Guiana), in northeastern Brazil, originally part of the Portuguese Empire, now corresponding to the Brazilian State of Amapá.

History 
The territories of the Guianas were made colonies from the 17th century by England, Netherlands, France, Portugal and Spain, resulting in its present division. The colonies were then:
 British Guiana, independent since 1966 with the name of Guyana;
 Spanish Guiana, the present southeastern Venezuela;
 French Guiana or Guyane, an overseas region and department of France;
 Dutch Guiana, independent since 1975 with the name of Suriname;
 Portuguese Guiana, later the Brazilian Guiana and now the Brazilian state of Amapá.
