Co-operative Republic of Guyana in the context of "Demerara"

Essequibo (/ˌɛsəˈkwiːboʊ/ ESS-ə-KWEE-boh; Dutch: Kolonie Essequebo [koːˈloːni ɛsəˈkʋeːboː]) was a Dutch colony in the Guianas and later a county on the Essequibo River in the Guiana region on the north coast of South America. It was a colony of the Dutch West India Company between 1616 and 1792 and a colony of the Dutch state from 1792 until 1815. It was merged with Demerara in 1812 by the British who took control. It formally became a British colony in 1815 until 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 Essequibo River.

Guyana was a predecessor to the modern-day Co-operative Republic of Guyana and an independent state that existed between 1966 and 1970.

Berbice (/bɜːrˈbiːs/) is a region along the Berbice River in Guyana, which was between 1627 and 1792 a colony of the Dutch West India Company and between 1792 and 1815 a colony of the Dutch state. After having been ceded to the United Kingdom of Great Britain and Ireland in the latter year, it was merged with Demerara-Essequibo to form the colony of British Guiana in 1831. It became a county of British Guiana in 1838 till 1958. In 1966, British Guiana gained independence as Guyana and in 1970 it became a republic as the Co-operative Republic of Guyana.

After being a hereditary fief in the possession of the Van Peere family, the colony was governed by the Society of Berbice in the second half of the colonial period, akin to the neighbouring colony of Suriname, which was governed by the Society of Suriname. The capital of Berbice was at Fort Nassau until 1790. In that year, the town of New Amsterdam, which grew around Fort Sint Andries, was made the new capital of the colony.
