Eli Whitney a U-S born inventor patented an invention called the cotton gin in 1794. The cotton gin 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 the success of the cotton gin Whitney saw little wealth from the invention due to patent infringement issues.His invention also offered southern planters a justification to maintain and expand slavery even as a growing number of Americans wanted it abolished. Due to his reputation for creating the cotton gin he later secured a major contract to build muskets for the U.S. government in which he promoted the idea of interchangeable parts that made assembly faster and for easier repair.<span />

The Haitian Revolution has often been described as the largest and most successful slave rebellion in the Western Hemisphere. Slaves initiated the rebellion in 1791 and by 1803 they had succeeded in ending not just slavery but French control over the colony. The Haitian Revolution, however, was much more complex, consisting of several revolutions going on simultaneously. These revolutions were influenced by the French Revolution of 1789, which would come to represent a new concept of human rights, universal citizenship, and participation in government.
