Caroní River
In 1732, the Swedes made an attempt to settle between Low Orinoco and the Barima River. Nevertheless, by 1737 the Major Sergeant Carlos Francisco Francois de Sucre y Pardo (Antonio José de Sucre's Grant-father) expelled them from the forts at "Barima," preventing the Swedish attempt of colonization by the time being. By 1745, the Dutch had several territories in the region, including Essequibo, Demerara, Berbice, and Surinam. Dutch settlements were also established on the Cuyuni River, Caroní River and Moruka River. Domingos, Bandeira Jerónimo and Roque described Essequibo and Demerara as "sophisticated and promising slave colonies".
