One of the issues at play in the interactions between the United States and the Republic of Texas was the eventual annexation of Texas by the U.S. There were two main difficulties with the issue of Texas joining the United States at the time: first, incorporating Texas into the Union might provoke Mexico; and second.

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.

Like Spain, Mexico also wished to encourage settlement in the state of Coahuila y Texas and passed colonization laws to encourage immigration. Thousands of Americans, primarily from slave states, flocked to Texas and quickly came to outnumber the Tejanos, the Mexican residents of the region.

Andrew Jackson was the president of the time when the idea of Manifest Destiny started. He didn’t annex Texas because it wanted to be a slave state. The Americans believed in Manifest Destiny and they accomplished that by defeating Mexico in the war and then taking over most of their territories.

The main reason for this was slavery. The US did not want to annex Texas because doing so would have upset the balance between slave states and free states that had been accomplished with the Missouri Compromise of 1820. When Texas became independent, it wanted to join up with the United States.
