This study deals with the economic and political impact of the American War of Independence (1775-1783) on the development of the British West Indian colonies. On the basis of extensive archival material and statistical data, the author demonstrates that the American Revolution not only cut off the British West Indies from its main source of food and plantation supplies, but also sparked a continuous fall in the production of sugar and other staples, leading to the economic decline of the sugar colonies at the end of the eighteenth century.
