 The British abolitionists focused on the slave trade, arguing that the trade was not necessary for the economic success of sugar on the British West Indian colonies.This argument was accepted by wavering politicians, who did not want to destroy the valuable and important sugar colonies of the British Caribbean.The British parliament was also concerned about the success of the Haitian Revolution, and they believed they had to abolish the trade to prevent a similar conflagration from occurring in a British Caribbean colony.
