This infamous incident was reported around the world and catapulted Guyana into the spotlight.
But Guyana's modern history began nearly 500 years earlier, when in 1498 Europeans made their way to South America.
Ensuing centuries saw seemingly never-ending battles between the Spanish, French, Dutch and British to claim this land as their own.
The Dutch had settled Guyana by the late 16th Century and in 1667 the Treaty of Breda ceded all the English colonies in the area known as Guiana to the Dutch.
Colonies continued to change hands until the Congress of Vienna awarded the settlements of Berbice, Demerara, and Essequibo to Great Britain; they were then united as British Guiana in 1831.
Slavery was abolished in 1834 and thousands of indentured labourers were bought to Guiana to work on the sugar cane plantations.
The majority came from India but smaller numbers were from Portugal and China.
For the most part, these diverse cultures co-existed peacefully, though racial tensions have erupted periodically during the later half of the 20th century between the Afro-Guyanese and the Indo-Guyanese.
Over the years, domestic politics have been somewhat turbulent particularly during the 1950s and 60s.
The Guyana flag
The British deemed the government to be pro-communist and suspended the constitution in 1953.
During the 1960s, there was much civil unrest and this was later suspected to have been funded or provoked by the US Central Intelligence Agency (CIA).
Independence was achieved in 1966 and Guyana became a republic in 1970.
It embarked on a socialist path that unfortunately led to economic ruin. But when Cheddi Jagan was elected as president in 1992, many international analysts considered it the first free election since independence.
Situated on the northeastern shoulder of the South American continent, Guyana's coastline is along the Atlantic Ocean and its many waterways reflect its namesake - Land of many waters.
The original inhabitants were Carab and Arawak tribes of Amerindians.

Economy: The Guyanese economy has demonstrated moderate economic growth due to expansion in its mining and agricultural sectors.
These industries are the chief economic activities of Guyana. However, a chronic shortage of skilled labour and a deficient infrastructure have been debilitating.
The chief export is bauxite. Manganese, gold and diamonds are also mined. The bauxite mining industry should benefit from its imminent restructuring and partial privatisation. Guyana has a large external debt and a dire need for foreign investment.
