Abolition of slavery in France In 1315, Louis X, king of France, published a decree proclaiming that "France signifies freedom" and that any slave setting foot on the French ground should be freed.

The French West Indies included Anguilla (briefly), Antigua and Barbuda (briefly), Dominica, Dominican Republic, Grenada, Haïti , Montserrat (briefly), Saint Lucia, Saint Vincent and the Grenadines, Sint Eustatius (briefly), St Kitts and Nevis (St Kitts, but not Nevis), Trinidad and Tobago (Tobago only), Saint Croix (briefly), Saint- Barthélemy (until 1784 when became Swedish for nearly a century), the northern half of Saint Martin, and the current French overseas départements of Martinique and Guadeloupe in the Caribbean sea.
