The Missouri compromise was after the Louisiana purchase in 1803. They divided into territories and the population grew and became states. Alabama and Illinois applied at the same time and Alabama became a slave state and Illinois became a free state. Missouri applied as a free state but had a debate with the south and congress made a compromise known as the Missouri compromise which said that Missouri would be added as a slave state but Maine would be a free state. A line was also drawn through the unincorporated western territories along the 36°30' parallel, dividing north and south as free and slave.  The Missouri Compromise was meant to create a balance between slave and non-slave states. With it, the country was equally divided between slave and free states. Admitting Missouri as a slave state gave the south one more state than the north. Adding Maine as a free state balanced things out again.
