The Haitian Revolution (1791-1804) and the subsequent emancipation of Haiti as an independent state provoked mixed reactions in the United States. Among many white Americans this led to uneasiness, instilling fears of racial instability on its own soil and possible problems with foreign relations and trade between the two countries; among enslaved black Americans it fueled hope that the principles of the recent American Revolution might be realized in their own liberation. US president Thomas Jefferson recognized that the revolution had the potential to cause an upheaval against slavery in the US not only by slaves, but by white abolitionists as well. Southern slaveholders feared the revolt might spread from the island of Hispaniola to their own plantations. Against this background and with the declared primary goal of maintaining social order in Haiti, the US , refusing acknowledgement of Haitian independence until 1862. The US also embargoed trade with the nascent state. American merchants had conducted a substantial trade with the plantations on Hispaniola throughout the 18th century, the French-ruled territory providing nearly all of its sugar and coffee. However, once the Haitian slave population emancipated itself, the US was reluctant to continue trade for fear of upsetting the evicted French on one hand and its Southern slaveholders on the other. Against this, there were anti-slavery advocates in northern cities who believed that consistency with the principles of the American Revolution — life, liberty and equality for all — demanded that the US support the Haitian people. One outcome of the Haitian Revolution for the US was the Louisiana Purchase. Having lost his control of the Caribbean landholding, Napoleon saw no further use for Louisiana. The US was only interested in the New Orleans area; however, the revolution enabled the sale of the entire territory west of the Mississippi River for around $15 million. This purchase more than doubled US territory. (en)
