John Tyler (1790 – 1862) was the tenth President of the United States (1841–1845). Born to an aristocratic Virginia family, Tyler served as a Virginia state legislator and governor. He came to national prominence at a time of political upheaval, serving as a U.S. representative, and U.S. senator before being elected Vice President in 1840. Upon the death of President William Henry Harrison only a month after his inauguration, a short Constitutional crisis arose over the succession process. Tyler was the first to succeed to the office of President on the death of the incumbent, in this case William Henry Harrison.
Tyler's opposition to federalism and emphatic support of states' rights endeared him to his fellow Virginians but alienated him from most of the political allies that brought him to power in Washington. Though he had several foreign policy achievements, his presidency was crippled by opposition from both parties. Near the end of his life he would side with the South in its secession from the United States. Although some have praised Tyler's political resolve, his presidency is generally held in low esteem by historians; today he is considered an obscure president, with little presence in the American cultural memory.
