Because the Europeans did not view the islands as their home, there was always a shortage of white women. One of the results of this was the development of an ever-growing class of mulattoes. More and more of them were granted their freedom. While these freedmen did not receive equal treatment with the whites, they were careful to preserve the advantages they held over the slaves. Many of them served in the militia to help keep the slaves under control. However, the threat of slave revolts continued. The greater the possibility of success, the greater the probability that slaves would take the risk of starting a revolt. All of the islands in the West Indies had a history of slave rebellion.
Undoubtedly, the most outstanding slave revolt in the western hemisphere took place in Haiti. During the French revolution, concepts of the rights of man spread from France to her colonies. In Haiti, the free mulattoes petitioned the French revolutionary government for their rights. The Assembly granted their request. However, the French aristocrats in Haiti refused to follow the directives of the Assembly. At this point, two free mulattoes, Vincent Oge and Jean Baptiste Chavannes, both of whom had received an education in Paris, led a mulatto rebellion. The Haitian aristocrats quickly and brutally suppressed it.
By this time, however, the concepts of the rights of man had spread to the slave class. In 1791, under the leadership of Toussaint l'Ouverture, the slaves began a long and bloody revolt of their own. Slaves flocked to Toussaint's support by the thousands until he had an army much larger than any that had fought in the American revolution, This revolt became entangled with the French revolution and the European wars connected with it. Besides fighting the French, Toussaint had to face both British and Spanish armies. None of them was able to suppress the revolt and to overthrow the republic which had been established in Haiti.
After Napoleon came to power in France, he sent a gigantic expedition under Leclerc to reestablish French authority in Haiti. While he claimed to stand for the principles of the revolution, Napoleon's real interest in Haiti was to make it into a base from which to rebuild a French empire in the western hemisphere. Toussaint lured this French army into the wilderness where the soldiers, who had no immunity to tropical diseases, were hit very hard by malaria and yellow fever.
Toussaint was captured by trickery, but his compatriots carried on the fight for independence. Finally, Napoleon was forced to withdraw from the struggle. One of the results of his failure to suppress the slave revolt in Haiti was his abandonment of his New World dreams and his willingness to sell Louisiana to the United States. Unfortunately, this meant new areas for the expansion of the plantation economy and slavery. In other words, the Haitian revolution was responsible for giving new life to the institution of slavery inside America.
American plantation owners were faced with a dilemma. The Louisiana Purchase, resulting from the revolution in Haiti, greatly expanded the possibilities of plantation agriculture. This meant a greater need for slave labor. However, they were not sure from which source to purchase these slaves. They hesitated to bring new slaves directly from Africa. They were also loath to bring seasoned slaves from the Caribbean. Events in Haiti had demonstrated that these Caribbean slaves might not be as docile as previously had been believed. Certainly, Americans did not want repetition of the bloody Haitian revolt within their own borders. Greedy men still bought slaves where they could, but many American slave owners were deeply disturbed and began to give serious thought to terminating the importation of African slaves to America.
