Why was Dred Scott important?

He was a slave who argued he was free.

His court case granted legal rights to slaves.

His court case ended the slavery argument.

He was an accomplished abolitionist lawyer.

Answer: He was a slave who argued he was free.

Explanation:

This was more process of elimination. Slavery ended on bloodshed.

The rights of slaves came with the end of the war (the 13th amendment notably)

And he was not a lawyer.

The correct answer is the first option: "He was a slave who argued he was free".

Explanation:

In 1846, this man argued that both he and his wife Harriet lived for 4 years in Illinois and Wisconsin where slavery was illegal and therefore considered that they should be released. This demand is made because he did not have the money to buy his freedom.

The United States Supreme Court ruled against Scott and also established that no person with an African heritage could have the right to citizenship. In that moment, the Supreme Court also states that Congress cannot prohibit slavery in federal territories.

At present, many people describe this historical event as an attack on human dignity since by 1850, slavery on the American continent had been eliminated almost entirely.
