who invented the cotton gin and what was its impact
Cotton gin
Handheld roller gins had been used in India and then other countries since at earliest 500 CE . The Indian worm - gear roller gin , invented some time around the sixteenth century , has , according to Lakwete , remained virtually unchanged up to the present time . A modern mechanical cotton gin was created by American inventor Eli Whitney in 1793 and patented in 1794 . Whitney 's gin used a combination of a wire screen and small wire hooks to pull the cotton through , while brushes continuously removed the loose cotton lint to prevent jams . It revolutionized the cotton industry in the United States , but also led to the growth of slavery in the American South as the demand for cotton workers rapidly increased . The invention has thus been identified as an inadvertent contributing factor to the outbreak of the American Civil War . Modern automated cotton gins use multiple powered cleaning cylinders and saws , and offer far higher productivity than their hand - powered forebears .
