The '''Missouri Compromise of 1820''' allowed for the entry of Maine into the Union as a free state, and Missouri as a slave state. It was further agreed that slavery was to be excluded from territory north of the 36°30′ parallel, or the remaining western territories. Before admission could be granted to Missouri a clause in the state's constitution provoked controversy: the exclusion of "free negroes and mulattoes". Under Whig Henry Clay's influence in the U.S. senate, an act of admission was passed, upon condition that the controversial exclusionary clause should "never be construed to authorize the passage of any law" impairing the privileges and immunities of free citizens. The compromise seemed deliberately ambiguous in that it could be interpreted to indicate that free blacks and mulattos did not qualify as United States citizens, which would be put to direct test years later with a slave named Dred Scott.
