Question

which statement explains why the thirteenth, fourteenth, and fifteenth amendments were added to the constitution? (1 point)

the union winning the civil war, ultimately abolishing slavery within the whole country
the revolutionary war, ultimately freeing colonists from the british monarchy
a rebellion led by former enslaved people
the confederate south winning the civil war

Explanation:

The Thirteenth, Fourteenth, and Fifteenth Amendments (the Reconstruction Amendments) were added after the Union won the Civil War. The Thirteenth Amendment abolished slavery. The Fourteenth Amendment granted citizenship and equal protection. The Fifteenth Amendment protected voting rights. The Revolutionary War (1775 - 1783) was long before these amendments. There was no successful rebellion led by formerly enslaved people that directly led to these amendments. If the Confederate South had won the Civil War, these pro - equality amendments would not have been passed.

Answer:

the Union winning the Civil War, ultimately abolishing slavery within the whole country
