The close interweaving of the colonial spheres of the majority of European powers inexorably raised slavery to an international plane: from then on anti-slavery too became a cosmopolitan movement, and these present studies strive to take account of this important innovation at the end of the eighteenth century.

This work, written in tribute to Léger Félicité Sonthonex, who was responsible for the first abolition in Santo Domingo in 1793, and to Victor Schoelcher, principal architect of the abolition of 1848, is intended to link two highly symbolic dates in the tragic history of the "first colonization": 1793 marks the beginning of the age of abolitions, yet it was not until half a century later that France, now republican once more, renewed links with the heritage of the Enlightenment and of Year II.
