USA HISTORY

Detailed explanation-1: -After months of debate, the Missouri Compromise saved the day: Missouri would be admitted as a slave state, and a new state-Maine-would be created as a free state. To avoid future problems, they also mapped out which parts of the rest of America’s territory could become slave and free states.

Detailed explanation-2: -The Missouri Compromise drew a line from the Mississippi River to the Pacific Ocean. Slavery would be allowed south of that line but not north of it. Because Iowa fell far north of the line, Iowa came into the Union as a “free” state without slavery.

Detailed explanation-3: -Iowa was admitted as a free state and Florida was admitted as a slave state, according to their respective state constitutions. The concurrent admission of the two states allowed the U.S. Senate to remain balanced in regard to the number of senators from free and slave states.

Detailed explanation-4: -West Virginia became the 35th state on June 20, 1863, and the last slave state admitted to the Union.
