Final answer:
The compromise ending the nullification crisis resulted in nullification being defeated, South Carolina staying in the Union, and the government retaining its trade regulation rights. However, the underlying conflict regarding states' rights and federal authority remained unresolved.
Step-by-step explanation:
The results of the compromise that ended the nullification crisis included the defeat of nullification, South Carolina remaining in the Union, and the affirmation of the federal government's right to regulate trade. Notably, Massachusetts did not secede from the Union as that was not related to this crisis. The Compromise Tariff of 1833 reduced tariff rates, which the nullifiers in South Carolina accepted. South Carolina made a symbolic gesture by nullifying the Force Bill, but this had little practical effect as the federal government ignored it. The crisis demonstrated a fundamental sectional conflict that would eventually lead to the Civil War, despite the momentary peace.
