Dred Scott |
|
MARCH 6 |
| 1857 In what became known as the Dred Scott Decision, the United States Supreme Court declared that no black -- free or slave -- could claim U.S. citizenship and that Congress could not prohibit slavery in U.S. territories. The Old Courthouse in Saint Louis where the Dred Scott trials took place (in 1847 and again in 1850) is preserved as part of the Jefferson Expansion National Memorial, a unit of the National Park Service. |
