James Polk (1795-1849) filled in as the eleventh U.S. president from 1845 to 1849. During his period in office, America’s region developed by more than 33% and stretched out over the mainland. Prior to his administration, Polk served in the Tennessee lawmaking body and the U.S. Congress; in 1839 he became legislative leader of Tennessee.
A Democrat who was generally obscure outside of political circles, Polk won the 1844 presidential political race. As president, he decreased duties, changed the national financial framework and resolved a boundary dispute with the British government. This dispute resolution helped to retain the Oregon Territory for the United States.
Polk additionally drove the country into the Mexican-American War (1846-48), in which the United States obtained California and a significant part of the present-day Southwest. Polk kept his campaign promise which was to be a one-term president and didn’t look for re-appointment. Not long after his tenure had elapsed, he passed on at age 53.
