On this day in 1794, young inventor Eli Whitney had his U.S. patent for the cotton gin approved, an invention that would have a great impact on social and economic conditions that led to the Civil War. How much of an impact the mechanical gin (which is short for “engine”) had on the retention of slavery in the South is still being debated. To be sure, the value of cotton as a cash crop grew astronomically in the decades following Whitney’s patent went into effect. By some estimates, the United States supplied three-quarters of the global cotton supply by the start of the Civil War.

But slavery, in addition to the cotton gin, was a key component of the cotton business. Whitney got the idea for the gin while working as a tutor near the estate of Catherine Greene in Savannah. Greene, the widow of General Nathanael Greene also may have suggested some of the concepts behind the gin to Whitney, according to one nineteenth-century author. The gin separated the sticky seeds from the fibers in short-staple cotton, which was easy to grow in the deep South but difficult to process. 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. During the constitutional debates of 1787, an end to the importation of slaves by the year 1808 was one of the compromises agreed to in Philadelphia. Some Founders may have believed that slavery would fade away in the United States because of social reasons or the unprofitability of slave-produced crops before the gin was invented. In 1807, Congress passed an act to make the slave-importation ban official. During the first cotton boom, the slave population in the South swelled to 4 million people, leaving slave owners with an ample population to maintain a workforce as the children of enslaved people continued to be born into slavery. By 1820, the nation was divided into Northern and Southern regions based on the legality of slavery in states and territories. Whitney never really profited from the invention that had a direct role in maintaining slavery as an institution. Although the Constitution’s Article 1, Section 8, gave Congress the power to create patent laws, the rules were difficult to enforce due to loopholes, and other planters started to build their own cotton gins. His patent was finally validated in 1807 after Whitney tried to collect damages in lawsuits for years. (Whitney later invented a process for interchangeable manufacturing parts for guns, which was very profitable.) One question that has been debated was the fate of slavery, independent of Whitney’s invention, and in particular, the idea that the cotton gin suddenly made slavery profitable. Alfred H. Conrad and John R. Meyer in their classic 1958 study about the issue argued that slavery depended on its economic survival for the spread of the institution to the Southwest in the 1860s. Also, Reconstruction historian and law professor Paul Finkleman argued in the Yale Journal of Law and the Humanities that the common perception of slavery as a dying institution before the cotton gin’s invention is misguided. “Slaves were a profitable investment before the cotton gin and an even more profitable investment after its invention,” he wrote in 2013. Regardless, the cotton gin was one of the significant inventions that changed American history in broad, generational ways. Scott Bomboy is the Editor In Chief of the National Constitution Center. As Eli Whitney left New England and headed South in 1792, he had no idea that he would patent a machine that would profoundly alter the course of American history. While in the South, Whitney quickly learned that Southern plantation owners were eager for a way to make cotton growing profitable. Whitney knew that if he could invent such a machine, he could apply to the federal government for a patent. Read more...

Teaching ActivitiesAdditional Background InformationEli Whitney and the Need for an Invention A recent graduate of Yale, Eli Whitney had given some thought to becoming a lawyer. But, like many college graduates, he had debts to repay first and needed a job. Reluctantly, he left his native Massachusetts to assume the position of private tutor on a plantation in Georgia. There Whitney quickly learned that Southern plantation owners were looking for a way to make cotton growing profitable at a time when tobacco was declining in profit due to over-supply and soil exhaustion. Long-staple cotton, which was easy to separate from its seeds, could be grown only along the coast. The one variety that grew inland had sticky green seeds that were time consuming to pick out of the fluffy white cotton bolls. Whitney was encouraged to find a solution to this problem by his employer, plantation owner Catherine Greene. Her financial support would be critical to his success. Whitney knew that if he could invent such a machine, he could apply to the federal government for a patent. If granted, he would have exclusive rights to his invention for 14 years based on the Patent Act of 1790, and he could hope to reap a handsome profit from it. The Constitution and Patent Law The Constitution empowers Congress "To promote the progress of science and useful arts by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries" in Article I, Section 8, Clause 8. Patent law must carefully balance the rights of the inventor to profit from his or her invention (through the grant of a temporary monopoly) against the needs of society at large to benefit from new ideas. The patent bill of 1790 enabled the government to patent "any useful art, manufacture, engine, machine, or device, or any instrument thereon not before known or used." The patent act of 1793 gave the secretary of state the power to issue a patent to anyone who presented working drawings, a written description, a model, and paid an application fee. Over time the requirements and procedures have changed. Today the U.S. Patent and Trademark Office is under the auspices of the Department of Commerce. Whitney Patents a Cotton Gin In hopes of making a patentable machine, Whitney put aside his plans to study law and instead tinkered throughout the winter and spring in a secret workshop provided by Catherine Greene. Whitney received a patent for his cotton gin in 1794 (his idea was based on earlier gins and also on ideas from other people, including Greene and enslaved laborers; some say that these were the rightful inventors of the cotton gin). Greene and her husband, Phineas Miller, financed Whitney and the legal battle that would ensue. A small gin could be hand-cranked; larger versions could be harnessed to a horse or driven by water power. "One man and a horse will do more than fifty men with the old machines," wrote Whitney to his father, "Tis generally said by those who know anything about it, that I shall make a Fortune by it." But patenting an invention and making a profit from it are two different things. Originally, Whitney opted to produce as many gins as possible, install them throughout Georgia and the South, and charge farmers a fee for doing the ginning for them. Their charge was two-fifths of the profit – paid to them in cotton itself. However, farmers and plantation owners throughout Georgia resented having to go to Whitney's gins where they had to pay what they regarded as an exorbitant tax. They began making their own versions of Whitney's gin and claiming they were "new" inventions. Greene and Miller brought costly suits against the owners of these pirated versions, but because of a loophole in the wording of the 1793 patent act, they were unable to win any suits until 1800, when the law was changed. Struggling to make a profit and mired in legal battles, Whitney and his partners finally agreed to license gins at a reasonable price. In 1802, South Carolina agreed to purchase Whitney's patent right for $50,000 but delayed in paying it. The partners also arranged to sell the patent rights to North Carolina and Tennessee. By the time the Georgia courts recognized the lack of patent protection that Whitney received, only one year of his patent remained. In 1808, and again in 1812, he petitioned Congress for a renewal of his patent. Effects of the Cotton Gin After the invention of the cotton gin, the yield of raw cotton doubled each decade after 1800. Demand was fueled by other inventions of the Industrial Revolution, such as machines to spin and weave it, and the steamboat to transport it. By 1850, America was growing three-quarters of the world's supply of cotton, most of it sent to New England or exported to England where it was manufactured into cloth. During this time tobacco fell in value, rice exports at best stayed steady, and sugar began to thrive, but only in Louisiana. By the mid-19th century, the South provided three-fifths of America's exports – most of it in cotton. The most significant effect of the cotton gin, however, was the growth of slavery. While it was true that the cotton gin reduced the labor of removing seeds, it did not reduce the need for enslaved labor to grow and pick the cotton. In fact, the opposite occurred. Cotton growing became so profitable for enslavers that it greatly increased their demand for both land and enslaved labor. In 1790, there were six "slave states"; in 1860 there were 15. From 1790 until Congress banned the slave trade from Africa in 1808, Southerners imported 80,000 Africans. By 1860, approximately one in three Southerners was an enslaved person. Because of the cotton gin, enslaved people labored on ever-larger plantations where work was more regimented and relentless. As large plantations spread into the Southwest, the price of enslaved labor and land inhibited the growth of cities and industries. In the 1850s, seven-eighths of all immigrants settled in the North, where they found 72% of the nation's manufacturing capacity. Epilogue While Eli Whitney is best remembered as the inventor of the cotton gin, he was also the father of the mass production method. In 1798, he figured out how to manufacture muskets by machine so that the parts were interchangeable. It was as a manufacturer of muskets that Whitney finally became rich. He died in 1825.

What was the effect of the cotton gin in the United States?While it was true that the cotton gin reduced the labor of removing seeds, it did not reduce the need for enslaved labor to grow and pick the cotton. In fact, the opposite occurred. Cotton growing became so profitable for enslavers that it greatly increased their demand for both land and enslaved labor.
What was the result of the invention of cotton gin?The cotton gin made the cotton industry of the South explode. Before its invention, separating cotton fibers from its seeds was a labor-intensive and unprofitable venture. After Whitney unveiled his cotton gin, processing cotton became much easier, resulting in greater availability and cheaper cloth.
