Governor of Tennessee, Speaker of the House of Representatives, and eleventh president of the United States, James K. Polk was a fierce Jacksonian who expanded the nation’s boundaries more than anyone since Thomas Jefferson. He is remembered today as one of the strongest presidents of the nineteenth century. Like Andrew Jackson before him, Polk increased the power of the presidency in ways that extend to this day. This digital edition of Polk’s correspondence includes the complete contents of the print edition’s fourteen volumes, plus an expanded supplementary calendar of documents only found here.
