Sandwiched between Venezuela and Suriname, the former British colony of Guyana is the only English-speaking country in South America.
Since independence from the UK in 1966, Guyana has seen fierce political rivalry between the two main ethnically-based parties.
Most of the country is covered in tropical rainforest and, despite having rich reserves of bauxite, gold and timber, it has struggled to overcome poverty and attract investment to bolster its economy.
A century-old border dispute with Venezuela has revived after the discovery of offshore oil reserves.

Retired army general David Granger beat incumbent President Donald Ramotar by a narrow margin in the May 2015 election, ending 23 years of rule by the Indian-dominated People's Progressive Party.
He forged a multi-ethnic coalition of his Partnership for National Unity and the Alliance for Change, with a pledge to end the racial divisions that have dominated Guyana's politics since independence in 1966.
He pledged to tackle corruption, nepotism and the waste of resources, but has been hampered by his coalition's slender parliamentary majority.
The constitution guarantees free speech, although officials are apt to resort to defamation laws, says Reporters Without Borders.
A bill passed in 2017 was criticised for requiring private broadcasters to carry a daily quota of government-chosen output.
Around 39% of Guyanese citizens were online by 2017.
