why was texas brought into the union after almost 10 years of independence
Texas annexation In 1843, U.S. President John Tyler, unaligned with any political party, decided independently to pursue the annexation of Texas in a bid to gain a base of popular support for another four years in office. His official motivation was to outmaneuver suspected diplomatic efforts by the British government for emancipation of slaves in Texas, which would undermine slavery in the United States. Through secret negotiations with the Houston administration, Tyler secured a treaty of annexation in April 1844. When the documents were submitted to the US Senate for ratification, the details of the terms of annexation became public and the question of acquiring Texas took center stage in the presidential election of 1844. Pro-Texas-annexation southern Democratic delegates denied their anti-annexation leader Martin Van Buren the nomination at their party's convention in May 1844. In alliance with pro-expansion northern Democratic colleagues, they secured the nomination of James K. Polk, who ran on a pro-Texas Manifest Destiny platform.
