evidence: Venezuelan President Nicolas Maduro is organising a referendum on Sunday to decide whether to create a new state in the Essequibo territory, an area currently under the control of neighbouring Guyana. Does Caracas have the means for its territorial ambitions, or is it just political grandstanding? [...] This situation is causing concern for Guyana's leaders. Caracas is threatening to deprive its eastern neighbour of more than half of its territory and to make the approximately 200,000 inhabitants of Essequibo Venezuelan citizens. [...] The territorial dispute over Essequibo dates back to the colonial era. In 1811, when Venezuela proclaimed its independence, it believed the region was part of its territory. Despite the claims, the United Kingdom, which occupied the territory of present-day Guyana, placed the region under the authority of the British crown. In 1899, an arbitration court ruled in favour of the UK, even though the United States had supported Caracas.
