BEP engraved portrait of Tyler as president.
John Tyler (March 29, 1790 – January 18, 1862) was the tenth President of the United States from 1841 to 1845 after briefly being the tenth Vice President (1841); he was elected to the latter office 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 supporter of states’ rights, and as president he adopted nationalist policies only when they did not infringe on the powers of the states. His unexpected rise to the presidency, with the resulting threat to the presidential ambitions of Henry Clay and other politicians, left him estranged from both major political parties.
Tyler, born to a prominent Virginia family, became a national figure at a time of political upheaval. In the 1820s the nation’s only political party, the Democratic-Republicans, split into factions. He was initially a Democrat, but opposed Andrew Jackson during the Nullification Crisis, seeing Jackson’s actions as infringing upon states’ rights, and criticized Jackson’s expansion of executive power during the Bank War. This led Tyler to ally with the Whig Party. Tyler served as a Virginia state legislator, governor, U.S. representative, and U.S. senator. He was put on the 1840 presidential ticket to attract states’ rights Southerners to a Whig coalition to defeat Martin Van Buren’s re-election bid.
With the death of President Harrison, Tyler became the first vice president to succeed to the presidency without election. After Harrison’s one-month term, Tyler served longer than any president in U.S. history not elected to the office. To forestall constitutional uncertainty, Tyler immediately took the oath of office, moved into the White House, and assumed full presidential powers, a precedent that governed future successions and was codified in the Twenty-fifth Amendment. A strict constructionist, Tyler found much of the Whig platform unconstitutional, and vetoed several of his party’s bills. Believing that the president should set policy rather than Congress, he sought to bypass the Whig establishment, most notably Kentucky Senator Henry Clay. Most of Tyler’s Cabinet resigned soon into his term, and the Whigs, dubbing him His Accidency, expelled him from the party. Tyler was the first president to see his veto of legislation overridden by Congress. Although he faced a stalemate on domestic policy, he had several foreign-policy achievements, including the Webster–Ashburton Treaty with Britain and the Treaty of Wanghia with Qing China.
The Republic of Texas separated from Mexico in 1836; Tyler, a firm believer in manifest destiny, saw its annexation as providing an economic advantage to the United States, and worked diligently to make it happen. He initially sought election to a full term as president, but after failing to gain the support of either Whigs or Democrats, he withdrew in support of Democrat James K. Polk, who favored annexation. Polk won the election, and Tyler signed a bill to annex Texas three days before leaving office. Under Polk, the process was completed. After the American Civil War began in 1861, Tyler won election to the Confederate House of Representatives shortly before his death. Although some have praised Tyler’s political resolve, his presidency is generally held in low regard by historians. He is considered an obscure president, with little presence in American cultural memory. https://en.wikipedia.org/wiki/John_Tyler.
