Andrew Jackson was born into a poor frontier family and orphaned at age 15. He became a lawyer and gained fame for his military service in the War of 1812. As president, Jackson faced two main crises - nullification, regarding states' rights to nullify federal tariffs, and the Bank War over rechartering the Second Bank of the United States. His supporters liked that he overcame poverty to become a war hero who stood up to banks, big business, Indians, and the wealthy. His presidency set important precedents regarding states' rights and the power of the presidency.
