 The French Revolution, in which Raynal and Gregoire were notable figures, did not initially have emancipation as a goal, but after failing to stamp out the Haitian Revolution, led by the devout Catholic ex-slave Toussaint L'Overture, and alarmed by British attempts to link up with the slave rebels, in 1794 the French entirely abolished slavery in all French territories.The British followed in 1807 with the Slave Trade Act 1807, which outlawed all international slave-trafficking, but not slave owning, which was legal in the British Empire until the Slavery Abolition Act 1833.From 1807 the British began to use their naval power and diplomatic pressure to lead the international movement eradicating international slave-trafficking completely, which was eventually almost entirely successful.
