Detailed explanation-1: -cotton gin, machine for cleaning cotton of its seeds, invented in the United States by Eli Whitney in 1793.
Detailed explanation-2: -The gin could remove the seeds from cotton quicker and more efficiently than the plantation’s enslaved labor. Whitney and Miller became business partners and, with the financial support of Greene, began to manufacture the gin for general use. Whitney and Miller patented the cotton gin in 1794.
Detailed explanation-3: -What did Eli Whitney invent? Eli Whitney’s most famous invention was the cotton gin, which enabled the rapid separation of seeds from cotton fibres. Built in 1793, the machine helped make cotton a profitable export crop in the southern United States and further promoted the use of slavery for cotton cultivation.
Detailed explanation-4: -The gin improved the separation of the seeds and fibers but the cotton still needed to be picked by hand. The demand for cotton roughly doubled each decade following Whitney’s invention. So cotton became a very profitable crop that also demanded a growing slave-labor force to harvest it.
