In his two terms as president, Andrew Jackson worked to implement his vision of a politics of opportunity for all white men. To open land for white settlement, he favored the relocation of all eastern Indian tribes. He dramatically confronted John C. Calhoun and South Carolina when that state tried to nullify the tariff of 1828. Disapproving of all government-granted privilege, Jackson challenged and defeated the Bank of the United States. In all this, he greatly enhanced the power of the presidency.
