Answer:
The answer is the invention of the cotton gin.
Explanation:
In 1794, U.S.-born inventor Eli Whitney (1765-1825) patented the cotton gin, a machine that revolutionized the production of cotton by greatly speeding up the process of removing seeds from cotton fiber. By the mid-19th century, cotton had become America’s leading export. Despite its success, the gin made little money for Whitney due to patent-infringement issues.
One inadvertent result of the cotton gin’s success, however, was that it helped strengthen slavery in the South. Although the cotton gin made cotton processing less labor-intensive, it helped planters earn greater profits, prompting them to grow larger crops, which in turn required more people.
