密苏里妥协
In the Compromise of 1850, Utah and New Mexico Territories had been organized without any restrictions on slavery, and many supporters of Douglas argued that the compromise had already superseded the Missouri Compromise. The territories were, however, given the authority to decide for themselves whether they would apply for statehood as either free or slaves states whenever they chose to apply. The two territories, however, unlike Nebraska, had not been part of the Louisiana Purchase and had arguably never been subject to the Missouri Compromise.
