James Knox Polk (November 2, 1795 – June 15, 1849) was the **11th president of the United States** (1845–1849). A protégé of Andrew Jackson and a champion of **Manifest Destiny**, Polk presided over one of the most consequential expansions of U.S. territory, including victory in the **Mexican–American War** and peaceful settlement of the **Oregon boundary**.
Early Life and Education
Polk was born near Charlotte, North Carolina, and moved with his family to Tennessee as a boy. Sickly in youth, he excelled academically, graduating first in his class from the **University of North Carolina**. He read law, became an attorney in Tennessee, and entered Democratic politics.
Early Political Career
Polk served in the **Tennessee legislature**, then in the **U.S. House of Representatives** (1825–1839), where he became **Speaker of the House** (1835–1839). He later served as **Governor of Tennessee**. In 1844 he emerged as a “dark horse” Democratic nominee for president.
Presidency (1845–1849)
Polk campaigned on four clear goals and largely achieved them:
- **Territorial expansion:** Asserted U.S. claims to the Oregon Country; negotiated the **Oregon Treaty (1846)** with Britain, setting the 49th parallel.
- **California and the Southwest:** Led the nation through the **Mexican–American War (1846–1848)**, resulting in the **Treaty of Guadalupe Hidalgo** and acquisition of vast territories (present-day CA, NV, UT, AZ, NM, and parts of CO/WY).
- **Tariff reduction:** Enacted the **Walker Tariff (1846)**, lowering rates and shifting toward revenue tariffs.
- **Independent Treasury:** Restored the **Independent Treasury System** (1846), separating federal finances from private banks.
Mexican–American War
Polk’s decision to send troops to the disputed Rio Grande sparked war with Mexico. U.S. forces captured California and New Mexico and occupied Mexico City. The victory dramatically expanded U.S. territory, but intensified sectional conflict over **slavery’s expansion** (e.g., the **Wilmot Proviso** debates).
Domestic Issues and Sectional Tension
While Polk avoided public agitation over slavery, the new lands reopened arguments between free and slave states, foreshadowing the crises of the 1850s. He also oversaw the establishment of the **Smithsonian Institution** and signed legislation founding the U.S. Naval Academy.
Later Life and Death
True to his pledge to serve only one term, Polk retired in March 1849. Exhausted from office and post-presidential travel, he died of illness at his Nashville home three months later.
Legacy
Polk is often ranked highly for effectiveness: he set clear objectives and achieved them, expanding the nation’s borders to the Pacific. Critics argue his expansionism hastened sectional strife. His presidency remains a case study in focused executive leadership.
