Importance of Cotton Gin

In the late 18th century, with the land used to grow tobacco nearly exhausted, the South faced an economic crisis, and the continued growth of slavery in America seemed in doubt. Around the same time, the mechanization of the textile industry in England led to a huge demand for American cotton, a southern crop whose production was unfortunately limited by the difficulty of removing the seeds from raw cotton fibers by hand. In 1793, a young Yankee schoolteacher named Eli Whitney invented the cotton gin, a simple mechanized device that efficiently removed the seeds. His device was widely copied, and within a few years the South would transition from the large-scale production of tobacco to that of cotton, a switch that reinforced the region’s dependence on slave labor.

Slavery itself was never widespread in the North, though many of the region’s businessmen grew rich on the slave trade and investments in southern plantations. Between 1774 and 1804, all of the northern states abolished slavery, but the so-called “peculiar institution” remained absolutely vital to the South. Though the U.S. Congress outlawed the African slave trade in 1808, the domestic trade flourished, and the slave population in the U.S. nearly tripled over the next 50 years. By 1860 it had reached nearly 4 million, with more than half living in the cotton-producing-producing states of the South.
