 However, during the Revolution, the National Convention voted to abolish slavery in February 1794.Under the terms of Amiens, Napoleon agreed to appease British demands by not abolishing slavery in any colonies where the 1794 decree had never been implemented.However, the 1794 decree was only implemented in Saint-Domingue, Guadeloupe and Guyane, and was a dead letter in Senegal, Mauritius, Reunion and Martinique, the last of which had been conquered by the British, who maintained the institution of slavery on that Caribbean island.
