Which year accounts for the emancipation of slaves?

Slavery was abolished in French colonies in 1794 (16 Pluviose Year II) during the French Revolution by the National Convention, led by figures like Robespierre and the Jacobins who had been influenced by the 1791 slave uprising in Saint-Domingue (Haiti). However, Napoleon later reinstated slavery in 1802. 1774, 1781, and 1789 are incorrect - though 1789 marked the start of the French Revolution, emancipation came several years later.
