Andrew Jackson was the 7th US President known for expanding executive power and populism. Under Jackson, the "spoils system" rewarded political supporters with government jobs. He also faced the Nullification Crisis over high tariffs, threatening force against states trying to nullify federal law. Jackson aggressively pursued the forced removal of Native Americans, like the Trail of Tears, to gain more land. His actions increased presidential authority and aligned the government more with common voters over elites.
