James Knox Polk was a pivotal figure in American expansion, responsible for the nation's second-largest territorial growth. A staunch advocate for territorial expansion, often against political opposition, he secured significant lands, reigniting fierce debate over slavery in new territories. His successful foreign policy and leadership in the Mexican-American War profoundly shaped the nation's expanding borders. Polk's administration also enacted significant economic reforms, including tariff adjustments and the establishment of a treasury system that endured for decades. He is recognized as one of the most effective presidents for his ability to set an agenda and achieve all its objectives.
