USA HISTORY

Detailed explanation-1: -When Texas emerged as an independent republic (1836-1845), the new nation faced tremendous challenges: the nation was deeply in debt and Mexico, refusing to recognize Texas independence, threated to reconquer the region. The United States had also refused Texas’s request to be annexed to the United States.

Detailed explanation-2: -Those against annexing Texas argued that it would spread slavery even further West and drive the United States closer to a civil war. Opponents also pointed out that Mexico did not want the United States to annex Texas and become its neighbor; they believed annexing Texas could lead to war with Mexico.

Detailed explanation-3: -His official motivation was to outmaneuver suspected diplomatic efforts by the British government for the 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.

Detailed explanation-4: -In 1844, Congress finally agreed to annex Texas. On December 29, 1845, Texas entered the United States as a slave state, broadening the irrepressible differences in the United States over the issue of slavery and setting off the Mexican-American War.
