Demerara (, ) is a historical region in the Guianas, on the north coast of South America, now part of the country of Guyana. It was a colony of the Dutch West India Company between 1745 and 1792 and a colony of the Dutch state from 1792 until 1815. It was merged with Essequibo in 1812 by the British who took control. It formally became a British colony in 1815 till Demerara-Essequibo was merged with Berbice to form the colony of British Guiana in 1831. In 1838, it became a county of British Guiana till 1958. In 1966, British Guiana gained independence as Guyana and in 1970 it became a republic as the Co-operative Republic of Guyana. It was located around the lower course of the Demerara River, and its main settlement was Georgetown.

The Amerindian were considered free people, and they were not allowed to enslave them. The first planter was Andries Pieterse who already owned a plantation in Essequibo. Half a year later, there were 18 large sugar plantations and 50 smaller plantations. The colony was initially governed from Fort Zeelandia by Laurens Storm van 's Gravesande, the governor of Essequibo. In 1750 he appointed his son Jonathan as Commander of Demerara. Demerara grew rapidly, and attracted many English planters. The Dutch West India Company, who had a monopoly on the slave trade, was unable to supply them, leading to illegal smuggling from English colonies. In 1755, Gedney Clarke, a Barbados merchant and plantation owner, requested political representation, therefore the administration was moved to the island of Borsselen, upriver near plantation Soesdyke which was
