Notes
↑Demerara was formerly a Colony of the Dutch West India Company between 1745 and 1792, then a colony of the Dutch state from 1792 until 1815. After the British took control, it merged with Essequibo in 1812 and before formally became a British colony in 1815. In 1831, Demerara-Essequibo merged with Berbice to form the colony of British Guiana in 1831, which became the County of British Guiana in 1838.
