USA HISTORY

Detailed explanation-1: -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 This provision held for 34 years, until it was repealed by the Kansas-Nebraska Act of 1854.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-2: -Anti-slavery supporters were outraged because, under the terms of the Missouri Compromise of 1820, slavery would have been outlawed in both territories since they were both north of the 36º30’ N dividing line between “slave” and “free” states.

Detailed explanation-3: -In 1780, Pennsylvania became the first state to abolish slavery when it adopted a statute that provided for the freedom of every slave born after its enactment (once that individual reached the age of majority). Massachusetts was the first to abolish slavery outright, doing so by judicial decree in 1783.

Detailed explanation-4: -Contents. The Missouri Compromise of 1820 was a law that tried to address growing sectional tensions over the issue of slavery.
