The British captured the island and drove out the French from Barrouallie during the Seven Years' War, a claim confirmed by the Treaty of Paris (1763). On taking control of the island in 1763, the British laid the foundations of Fort Charlotte and also brought with them enslaved African prisoners of war to work on the island plantations. The Black Caribs however, opposed to the British presence, entered into open conflict against the British, starting the First Carib War, which lasted from 1772 to 1773.
