Answer:
1. Eleven.
2. Missouri.
3. Henry Clay.
4. Maine.
5. Missouri Compromise.
Step-by-step explanation:
The 13th Amendment of 1865 was an amendment to the Constitution of the United States of America which formally abolished slavery and involuntary servitude except as a punishment for a crime committed by a convict within the jurisdiction.
In 1819, eleven (11) states in the Union permitted slavery and eleven (11) did not. The states that didn't permit slavery were referred to as free states and they included California, Minnesota, Iowa, New Jersey, Maine, Illinois, Pennsylvania, Ohio, Oregon, etc. On the other hand, the states that permitted slavery were known as slave states and they included Florida, Alabama, Georgia, Maryland, Kentucky, Texas, Missouri, Mississippi, etc.
The request by Missouri for admission as a state caused a debate, because its constitution allowed slavery. Henry Clay suggested that Congress admit Missouri as a slave state and Maine as a free state. Clay’s proposal, called the Missouri Compromise, passed in 1820.
