Upon taking office in 1828, President Jackson faced crises over both the tariff and Native American removal. The tariff divided the country between northern states that supported it and southern states that opposed it. John C. Calhoun advocated for states' rights to nullify federal laws like the tariff. In response, Jackson vigorously asserted federal authority. Meanwhile, Jackson pushed Congress to pass the Indian Removal Act of 1830 despite a Supreme Court ruling, leading to the forced removal of the Cherokee on the Trail of Tears.
