James K. Polk

The Expansionist US President

Definition

James K. Polk (1795-1849) was an American lawyer and politician who served as the eleventh president of the United States. A protégé of Andrew Jackson (1767-1845), he was the dark-horse candidate of the Democratic Party in the US Presidential Election of 1844, running on a platform of expansionism and 'Manifest Destiny'. During his single term, Polk settled a boundary dispute with Britain over the Oregon Territory and oversaw the Mexican-American War (1846-1848), which resulted in Mexico's cession of 529,000 square miles (1,370,103 km²) of land to the US. Polk, whose health was fragile to begin with, often overworked himself, likely contributing to his death only three months after leaving office in 1849.
