Question

Which reason led south carolina to secede from the union?.

Answer 1

The escalating controversy over the expansion of slavery into the territory acquired from Mexico

Step-by-step explanation:

The escalating controversy over the expansion of slavery into the territory acquired from Mexico prompted South Carolina's secession crisis of 1850 - 51. The Compromise of 1850 and the lack of broad-based support for secession in the South ended this crisis, but secessionists awaited their next opportunity.
