Removing seeds from newly picked cotton is not as simple as it sounds. Cotton is sticky when removed from the plant, and pulling the seeds from its grasp is difficult. Throughout the 1700s, cotton production was expensive because of the huge amount of labor necessary to remove the seeds. All was changed with the invention of the cotton gin. What once was painstakingly slow was now relatively fast. By the end of the 18th century, demand for cotton was increasing as power looms were able to turn out great quantities of cloth. With the cotton gin, southern cotton plantations could now supply the world's demand.
Ironically, the man who would make cotton king was born to a Massachusetts farmer. Almost immediately after graduating from Yale University, Eli Whitney traveled south. While staying at the Savannah plantation of Mrs. Nathanael Green in 1792, the widow of the Revolutionary War general, Whitney created the device that changed the world. Whitney built a machine that moved stiff, brushlike teeth though the raw cotton. To his delight, the teeth removed a very high percentage of the nettlesome seeds. Up to this point, it took up to 10 hours to produce a pound of cotton, with very little profit. The cotton gin ultimately grew to produce a thousand pounds of cotton per day with relatively little expense.
As an indication of the impact of this invention, the total amount of cotton being exported was about 138,000 pounds in the year the cotton gin was invented. Two years later, the amount of cotton being exported rose ten-fold, to 1,600,000 pounds. Before the gin, the prevailing thinking of the leaders of the country was that slavery would gradually disappear. This all changed when slaves could be used to cultivate millions of pounds of cotton for markets all over the world. Eli Whitney never made a cent on his invention because it was widely reproduced before it could be patented. Determined to duplicate his inventive success, he developed the milling machine, which led to the development of interchangeable parts and the northern factory system. This one individual played a great part in creating the industrial north, as well as the plantation south.
This phenomenal and sudden explosion of success of the cotton industry gave slavery a new lease on life. Prior to this, most thoughtful Southerners, including Washington and Jefferson, had seen slavery as an evil that must eventually be swept away. But with the southern economy now reliant on cotton, these beliefs were seen as old-fashioned, and slavery now was seen as an institution to be cherished. That Cotton was King was now well understood in the south. It became the foundation of southern economy, southern culture, and southern pride.
