Input: Context: John Tyler (March 29, 1790 January 18, 1862) was the tenth President of the United States (184145). He was also, briefly, the tenth Vice President (1841), elected to that office on the 1840 Whig ticket with William Henry Harrison. Tyler became president after Harrison's death in April 1841, only a month after the start of the new administration. Known to that point as a supporter of states' rights, which endeared him to his fellow Virginians, his actions as president showed that he was willing to back nationalist policies as long as they did not infringe on the powers of the states. Still, the circumstances of his unexpected rise to the presidency, and its threat to the presidential ambitions of Henry Clay and other politicians, left him estranged from both major parties. A firm believer in manifest destiny, President Tyler sought to strengthen and preserve the Union through territorial expansion, most notably the annexation of the independent Republic of Texas in his last days in office., Henry Clay, Sr. (April 12, 1777 June 29, 1852) was an American lawyer and planter, statesman, and skilled orator who represented Kentucky in both the United States Senate and House of Representatives. He served three non-consecutive terms as Speaker of the House of Representatives and served as Secretary of State under President John Quincy Adams from 1825 to 1829. Clay ran for the presidency in 1824, 1832 and 1844, while also seeking his party's nomination in 1840 and 1848. However, he was unsuccessful in all of his attempts to reach his nation's highest office. Despite his presidential losses, Clay remained a dominant figure in the Whig Party, which he helped found in the 1830s., John Nelson ( June 1 , 1791 -- January 18 , 1860 ) was Attorney General of the United States from 1843 to 1845 under John Tyler ., William Henry Harrison Sr. (February 9, 1773 April 4, 1841) was the ninth President of the United States (1841), an American military officer, and the last president born as a British subject. He was old at the time of his inauguration. He died of complications from pneumonia days into his term, serving the shortest tenure in United States presidential history. He was the first president to die in office, and his death sparked a brief constitutional crisis, but its resolution left unsettled many questions following the presidential line of succession in regard to the Constitution until the passage of the Twenty-fifth Amendment to the United States Constitution in 1967. He was the grandfather of Benjamin Harrison, who served as the 23rd President from 1889 to 1893., The Republic of Texas (Spanish: "Republica de Texas") was an independent sovereign country in North America that existed from March 2, 1836, to February 19, 1846. It was bordered by Mexico to the west and southwest, the Gulf of Mexico to the southeast, the two U.S. states of Louisiana and Arkansas to the east and northeast, and United States territories encompassing the current U.S. states of Oklahoma, Kansas, Colorado, and Wyoming to the north. The citizens of the republic were known as Texians., Subject: john nelson , Relation: member_of_political_party, Options: (A) military (B) republic (C) union (D) whig party
