USA HISTORY

Detailed explanation-1: -A staunch defender of the institution of slavery, and a slave-owner himself, Calhoun was the Senate’s most prominent states’ rights advocate, and his doctrine of nullification professed that individual states had a right to reject federal policies that they deemed unconstitutional.

Detailed explanation-2: -He served two terms as Vice President: in 1825 under John Quincy Adams and again in 1829 under Andrew Jackson. He resigned the position of Vice President in 1832 and returned to South Carolina as a Senator, a position he held for the following 11 years.

Detailed explanation-3: -Calhoun, in fact, despised Jackson’s efforts and wanted him arrested and tried for his actions, which he deemed dangerous and illegal. True to his corrupt character, though, Calhoun intentionally misled Jackson, portraying himself in private correspondence as Jackson’s most reliable ally.
