The Missouri Compromise (1820) was supposed to help settle the issue of slavery in the new territories acquired by the United States. In this compromise, the 36'30 line was established. Any new territory that was added to the US that was north of this line would be considered a free state. Any new territory that was added to the US that was south of this line would be considered a slave state. This line caused a significant problem for California because the 36'30 cut California into two pieces. At this time, having a half free half slave state was not an option.
