USA HISTORY

Detailed explanation-1: -Congress adopted this legislation and admitted Missouri as a slave state and Maine as a non-slave state at the same time, so that the balance between slave and free states in the nation would remain equal.

Detailed explanation-2: -Contents. The Missouri Compromise of 1820 was a law that tried to address growing sectional tensions over the issue of slavery. By passing the law, which President James Monroe signed, the U.S. Congress admitted Missouri to the Union as a state that allowed slavery, and Maine as a free state.

Detailed explanation-3: -Congress established Maine as the 23rd state under the Missouri Compromise of 1820. This arrangement allowed Maine to join the Union as a free state, with Missouri entering a year later as a slave state, thereby preserving the numerical balance between free and slave states in the nation.

Detailed explanation-4: -Congress approved the compromise and granted Maine statehood in March 1820. Due to further concerns with a provision in Missouri’s constitution, however, a “second Missouri compromise” was necessary. The Missouri territorial legislature approved this compromise in June 1821, and Congress granted Missouri statehood.

Detailed explanation-5: -The Missouri Compromise was accepted because it: 1) maintained congressional balance in the Senate, 2) allowed for certain new territories to be slave states, and 3) allowed certain new territories to be non-slavery states.
