Hello! who was involved in the Dred Scott V. Sandford case? Please give a little description not just names.

the Dred Scott V. Sandford case

Explanation:

Dred Scott was an enslaved African American, and his court case for freedom raised hostility between the south and the North. Dred Scott was born inside slavery, and from 1833 to 1843, he resided in Illinois, where slavery was forbidden. Upon coming to Missouri, Dred Scott appealed for his freedom from slavery, insisting that his residence in non-slavery territory gave him free. As the case reached the Supreme Court, the tension further increases between North and South. Since the 1820s, two parties had compromised on the Missouri Compromise. The North was not happy with the court decision as they believed the case gave Southern slaveholders growing power.
