Who was dred Scott and what is his importance to this time period?

Dred Scott was an enslaved African American man who famously sued for his freedom in the landmark Supreme Court case Dred Scott v. Sandford (1857). The Court ruled that Scott, as a Black man, was not a citizen and therefore had no right to sue, further entrenching the institution of slavery and inflaming sectional tensions between the North and South. This decision effectively invalidated the Missouri Compromise, contributing to the rising conflict that ultimately led to the Civil War. Scott's case highlighted the deep-seated issues of race and rights in America, making it a pivotal moment in the fight for civil rights.
