Dred Scott, a black slave who lived in the free state of Illinois and the free territory of Wisconsin  appealed to the Supreme Court in an attempt to be granted his freedom before moving back to the slave state of Missouri. The controversy surrounding the case was that slaves were property, they were not citizens and held no rights to sue. While the language of the Constitution 'all men were created equal' was challenged, the case had a disappointing outcome for Dred Scott. On the positive side, the case brought slavery to the attention of the nation. The U.S. Supreme Court on March 6, 1857, ruled 7–2 that a slave who had resided in a free state and territory ,where slavery was prohibited was not thereby entitled to his freedom.

the intolerable acts were punitive laws passed by the british parliament in 1774 after the boston tea party. in great britain, these laws were referred to as the coercive acts.
