How did the Haitian Revolution allow the US to buy Louisiana from the French?

The Haitian Revolution (1791-1804) significantly weakened French colonial power in the Americas, prompting Napoleon Bonaparte to reconsider his ambitions in the region. With the loss of Haiti, a key base for French operations, maintaining control over Louisiana became less strategic and more costly for France. Consequently, in 1803, Napoleon decided to sell the vast territory of Louisiana to the United States, allowing the U.S. to expand its territory and influence. This sale was finalized for $15 million, effectively doubling the size of the nation.
