James K. Polk: A Clear and Unquestionable Destiny (Biographies in American Foreign Policy)

James K. Polk's four years in office marked the greatest period of territorial acquisition in the history of the country-what New York journalist John O'Sullivan termed as the 'Manifest Destiny' of the United States to expand across the continent. By the end of Polk's presidency in 1849, U.S. possessions included the California, Oregon, and New Mexico territories. In addition, Texas had become part of the Union.

This fascinating biography of our eleventh president and his successful efforts for expansion of U.S. territory will be of interest to students studying United States history, foreign policy, and the massive territorial expansion in the 1840s known as Manifest Destiny.
