• This article re-examines the declining influence of Jamaican sugar planters within the British Empire during the period between the outbreak of the American Revolution in 1775 and Parliament’s decision to abolish the slave trade in 1807. Much of the existing scholarship emphasises the consequences of the American Revolutionary War and rise of abolitionism during the 1780s as pivotal to the fall of the planters. This article argues that those challenges did not determine the fate of the Jamaican planters. Rather, it was the radicalisation of the French and Haitian Revolutions, and the extended period of war that began in 1793, that led to their eventual defeat over the question of the slave trade.
