What was the largest French slave colony of North America?
French colonial empire
As the French empire in North America grew, the French also began to build a smaller but more profitable empire in the West Indies. Settlement along the South American coast in what is today French Guiana began in 1624, and a colony was founded on Saint Kitts in 1625 (the island had to be shared with the English until the Treaty of Utrecht in 1713, when it was ceded outright). The "Compagnie des Îles de l'Amérique" founded colonies in Guadeloupe and Martinique in 1635, and a colony was later founded on Saint Lucia by (1650). The food-producing plantations of these colonies were built and sustained through slavery, with the supply of slaves dependent on the African slave trade. Local resistance by the indigenous peoples resulted in the Carib Expulsion of 1660. France's most important Caribbean colonial possession was established in 1664, when the colony of Saint-Domingue (today's Haiti) was founded on the western half of the Spanish island of Hispaniola. In the 18th century, Saint-Domingue grew to be the richest sugar colony in the Caribbean. The eastern half of Hispaniola (today's Dominican Republic) also came under French rule for a short period, after being given to France by Spain in 1795.
Ivory Coast
Compared to neighboring Ghana, Ivory Coast, though practicing slavery and slave raiding, suffered little from the slave trade as such. European slave and merchant ships preferred other areas along the coast. The earliest recorded European voyage to West Africa was made by the Portuguese in 1482. The first West African French settlement, Saint Louis, was founded in the mid-17th century in Senegal, while at about the same time, the Dutch ceded to the French a settlement at Goree Island, off Dakar. A French mission was established in 1637 at Assinie near the border with the Gold Coast (now Ghana). The Europeans suppressed the local practice of slavery at this time, and forbade the trade to their merchants.
