John Tyler [SEP] Introduction
John Tyler (March 29, 1790 – January 18, 1862) was the tenth president of the United States from 1841 to 1845 after briefly serving as the tenth vice president in 1841; he was elected vice president on the 1840 Whig ticket with President William Henry Harrison. Tyler ascended to the presidency after Harrison's death in April 1841, only a month after the start of the new administration. He was a stalwart supporter and advocate of states' rights, and he adopted nationalistic policies as president only when they did not infringe on the powers of the states. His unexpected rise to the presidency posed a threat to the presidential ambitions of Henry Clay and other politicians, and left Tyler estranged from both major political parties.
