Early life

James Knox Polk was born on November 2, 1795, in a log cabin in Pineville, North Carolina. He was the first of 10 children born into a family of farmers. His mother Jane named him after her father, James Knox. His father Samuel Polk was a farmer, slaveholder, and surveyor of Scots-Irish descent. The Polks had immigrated to America in the late 17th century, settling initially on the Eastern Shore of Maryland but later moving to south-central Pennsylvania and then to the Carolina hill country.

The Knox and Polk families were Presbyterian. While Polk's mother remained a devout Presbyterian, his father, whose own father Ezekiel Polk was a deist, rejected dogmatic Presbyterianism. He refused to declare his belief in Christianity at his son's baptism, and the minister refused to baptize young James. Nevertheless, James' mother "stamped her rigid orthodoxy on James, instilling lifelong Calvinistic traits of self-discipline, hard work, piety, individualism, and a belief in the imperfection of human nature", according to James A. Rawley 's American National Biography article.

In 1803, Ezekiel Polk led four of his adult children and their families to the Duck River area in what is now Maury County, Tennessee; Samuel Polk and his family followed in 1806. The Polk clan dominated politics in Maury County and in the new town of Columbia. Samuel became a county judge, and the guests at his home included Andrew Jackson, who had already served as a judge and in Congress. James learned from the political talk around the dinner table; both Samuel and Ezekiel were strong supporters of President Thomas Jefferson and opponents of the Federalist Party.

Polk suffered from frail health as a child, a particular disadvantage in a frontier society. His father took him to see prominent Philadelphia physician Dr. Philip Syng Physick for urinary stones. The journey was broken off by James's severe pain, and Dr. Ephraim McDowell of Danville, Kentucky, operated to remove them. No anesthetic was available except brandy. The operation was successful, but it may have left James impotent or sterile, as he had no children. He recovered quickly and became more robust. His father offered to bring him into one of his businesses, but he wanted an education and enrolled at a Presbyterian academy in 1813. He became a member of the Zion Church near his home in 1813 and enrolled in the Zion Church Academy. He then entered Bradley Academy in Murfreesboro, Tennessee, where he proved a promising student.

In January 1816, Polk was admitted into the University of North Carolina at Chapel Hill as a second-semester sophomore. The Polk family had connections with the university, then a small school of about 80 students; Samuel was its land agent in Tennessee and his cousin William Polk was a trustee. Polk's roommate was William Dunn Moseley, who became the first Governor of Florida. Polk joined the Dialectic Society where he took part in debates, became its president, and learned the art of oratory. In one address, he warned that some American leaders were flirting with monarchical ideals, singling out Alexander Hamilton, a foe of Jefferson. Polk graduated with honors in May 1818.

After graduation, Polk returned to Nashville, Tennessee to study law under renowned trial attorney Felix Grundy, who became his first mentor. On September 20, 1819, he was elected clerk of the Tennessee State Senate, which then sat in Murfreesboro and to which Grundy had been elected. He was re-elected clerk in 1821 without opposition, and continued to serve until 1822. In June 1820, he was admitted to the Tennessee bar, and his first case was to defend his father against a public fighting charge; he secured his release for a one-dollar fine. He opened an office in Maury County and was successful as a lawyer, due largely to the many cases arising from the Panic of 1819, a severe depression. His law practice subsidized his political career.
