Dred Scott is man who was born into slavery, and was owned by John Emerson, a man of Missouri. Under the ownership of Emerson, Dred Scott was taken to Missouri to Illinois to Wisconsin due to Emerson's taking part in military services.
In 1843 Emerson died in Missouri, as earlier in the 1840s he and his wife along with the Scotts all returned to Missouri. In 1846, Scott sued for his freedom as he had lived on a free state and a free territory. It took eleven years to reach the court.
"The verdict was a bombshell." The Court ruled ruled that his travels to Illinois to Wisconsin territory did not make him free after his return to Missouri. The Court also ruled that due to him being a black man, Dred Scott was not recognized as a citizen of the United States and overall this act and the act of assisting him was unconstitutional.
