In 1824 Venezuela appointed José Manuel Hurtado as its new Ambassador to Britain. Hurtado officially presented to the British government Venezuela's claim to the border at the Essequibo River, which was not objected to by Britain. However, the British government continued to promote colonization of territory west of the Essequibo River in succeeding years. In 1831, Britain merged the former Dutch territories of Berbice, Demerara, and Essequibo into a single colony, British Guiana.
