evidence: Sunday’s referendum will be held over the fate of Essequibo, an oil-rich Guyana-ruled region that Venezuela claims as its own. [...] The referendum will ask Venezuelans five questions, including if they agree with creating a new state called Guayana Esequiba in the Essequibo region, granting its population Venezuelan citizenship as well as identity cards and incorporating that state into the map of Venezuelan territory. [...] The territory larger than Greece, known as "The Essequibo," amounts to more than two-thirds of the territory of Guyana and is home to 125,000 of its 800,000 citizens.
