Guyana, officially the Co-operative Republic of Guyana and previously known as British Guiana, is the only state of the Commonwealth of Nations on mainland South America. On the northern coast of the continent, it is bordered to the east by Suriname, to the south and southwest by Brazil, to the west by Venezuela, and on the north by the North Atlantic Ocean. At 215,000 km2, it is the third smallest state on the mainland of South America (after Suriname and French Guiana). Its estimated population is approximately 860,000. It is one of the four non-Spanish-speaking territories on the continent, along with the states of Brazil (Portuguese) and Suriname (Dutch), and the French overseas region of French Guiana (French). Culturally, Guyana associates primarily with the English-speaking Caribbean states, such as Jamaica and Trinidad and Tobago.
