As a result of the Dred Scott decision, the Missouri Compromise was declared unconstitutional.

Explanation:

Dred Scott, born in 1795, died on September 17, 1858, was an African American slave, famous for the lawsuit he pursued for his family's rights.

In 1834, Dred Scott was taken by his owner from Missouri to Illinois, where he got married, and then followed his owner back to Missouri. Later he opened a process in which he claimed that he and his family were free citizens, for the long time they had been resident in a free state such as Illinois. The process was dismissed differently in different instances. The United States Supreme Court ruled in 1856 to Scott's disadvantage, stating that he was a private property of his owners and therefore he couldn't fill a lawsuit, as he was not a citizen. Dred Scott v. Sandford addressed several important principles in the United States, including the unconstitutionality of the Missouri Compromise.
