Effect on cotton production and expansion of slavery Cheap cotton textiles increased the demand for raw cotton; previously, it had primarily been consumed in subtropical regions where it was grown, with little raw cotton available for export. Consequently, prices of raw cotton rose. Some cotton had been grown in the West Indies, particularly in Hispaniola, but Haitian cotton production was halted by the Haitian Revolution in 1791. The invention of the cotton gin in 1792 allowed Georgia green seeded cotton to be profitable, leading to the widespread growth of cotton plantations in the United States and Brazil. In 1791 world cotton production was estimated to be 490,000,000 pounds with U.S. production accounting to 2,000,000 pounds.  By 1800 U.S. production was 35,000,000 pounds, of which 17,790,000 were exported.  In 1945 the U.S. produced seven-eights of the 1,169,600,000 pounds of world production.
