This Compromise said that each slavewas worth three fifths of a person when it came to voting. The Three Fifth Compromise led to anincreasing in sectionalism.In 1793, the cotton gin, which was a device that gathered the seeds out of cotton fifty times faster than by hand, was invented. This invention was thought to take the place of slaves, but rather, it increased the demand of slaves all the more. The territory of Louisiana was bought in 1803. This purchase caused the Americanpeople to move out west and investigate the land. This was known has Westward Expansion. AsAmericans pushed west, the issue of slavery came to the forefront. The big question was wouldthe new territories of America become slave or free?In 1820, the Missouri Compromise was formed. The first confrontation over slavery inthe west caused the compromise to come about. Missouri applied to become a slave state, but indoing this, it would upset the balance of power in the senate. So, it was suggested that Missourienter in as a slave state and Maine as a free state to keep the balance of power. This compromisecooled sectional differences for a short time.
