USA HISTORY

Detailed explanation-1: -At the time, there were 22 states, half of them free states and half of them slave states. The Senate passed a bill allowing Maine to enter the Union as a free state and Missouri to be admitted without restrictions on slavery.

Detailed explanation-2: -The Missouri Compromise also proposed that slavery be prohibited above the 36º 30’ latitude line in the remainder of the Louisiana Territory. This provision held for 34 years, until it was repealed by the Kansas-Nebraska Act of 1854.

Detailed explanation-3: -At the time, there were 11 free states and 10 slave states. Southern congressmen feared that the entrance of Missouri as a free state would upset the balance of power between North and South, as the North far outdistanced the South in population, and thus, U.S. representatives.

Detailed explanation-4: -Enacted in 1820 to maintain the balance of power in Congress, the Missouri Compromise admitted Missouri as a slave state and Maine as a free state.

Detailed explanation-5: -Article 1, Section 2, of the US Constitution supplemented legislative representation in states whose residents owned slaves. Known as the Three-Fifths Clause, or the “federal ratio", three-fifths of the slave population was numerically added to the free population.
