Dred Scott Vs. Stanford case was heard in Supreme court of US which issued its final ruling saying that Africans whether free or slaves were not the citizens of US.
Explanation:
Dred Scott who is a plaintiff and a slave was bought by John Emerson in Missouri. Later Emerson came along with Dred Scott to Illinois where Scott married and as they were returning to Missouri, Emerson died. Now Dred Scott decided to sue for his freedom in the federal court. He claimed he was free as he lived in the free state.
Robert Taney who was the chief justice issued the land mark decision that African american though free or slave were not the citizen of US and hence Dred Scott had no right to sue in the federal court. Dred Scott lost his case and this ruling was condemned universally as one of the racism based verdicts which paved way for the amendments of the statutes pertaining to the rights of African Americans.
Denmark Vesey was a Former Slave who gained his own freedom for himself. He fight Slavery by organizing the biggest Slave Revolts in the U.S History, with more than 1,848 members joining his Revolt. He was executed for his revolt in June 1822
