Why did some members of the us congress oppose the annexation of texas?
Answer and Explanation:
The administration rejected the proposal, fearing reprisal from Mexico and the controversy that would follow the addition of another slave state.
Residents of Maine petitioned Congress against the annexation of Texas, citing three reasons. First, Mexico did not recognize Texas's independence, so annexation might provoke a war. Second, they opposed the expansion of slavery, which Texas allowed.
Most northern states had laws against slavery. Annexing Texas would add a slaveholding state to the Union. This would give the states that allowed slavery more votes in the U.S. House of Representatives and the Senate.
The United States didn't immediately annex Texas because Northerners opposed to slavery objected to the annexation of more slave territory and didn't want slave states to outnumber free states. Many Americans also feared that annexation would lead to war with Mexico.
One argument against annexing Texas to the U.S. was that the annexation might give more power to the supporters of slavery. Texas was annexed because President Tyler wanted to help his troubled administration.
Two controversial issues — the extension of slavery and a possible war with Mexico — proved to be major roadblocks to achieving statehood for nearly ten years. By 1844, U.S. supporters of annexation had made progress in their plan to unite Texas with the United States.
The Texas Annexation is important to United States history because it led to the addition of Texas as the 28th state in the Union, and set the stage for the outbreak of the Mexican-American War in 1846.
The Republic of Texas pre-annexation.
President John Tyler made the annexation of Texas a priority, and in the closing days of his presidency, Congress voted to make Texas a state—though it was not until December 1845 that, under President James K. Polk, Texas formally achieved statehood.

What is annexation and how did it affect Texas?
Annexation was approved by the Texas and U.S. congresses in 1845, and the transfer of authority from the republic to the state of Texas took place in 1846. One unique feature of the annexation agreements was a provision permitting Texas to retain title to its public lands.
Texas officially became part of the United States on December 29, 1845. Terms of the annexation agreement were generous to the new state, with Texas retaining all of its public lands and the United States paying $5 million to ease its debts.

annexation, a formal act whereby a state proclaims its sovereignty over territory hitherto outside its domain. Unlike cession, whereby territory is given or sold through treaty, annexation is a unilateral act made effective by actual possession and legitimized by general recognition.
The Texas Revolution (1835–1836) was an uprising in the Mexican state of Coahuila and Texas that led to the establishment of the Republic of Texas. The independent state played an important role in America's Manifest Destiny when Texas was annexed by the United States in 1845.
Answer and Explanation: The annexation of Texas did not cause the Civil War, it did help to provoke the Mexican-American War, which in turn led to more than a decade of divisive debates of the expansion of slavery. Those debates resulted in southern secession from the Union and the Civil War.
Texas Revolution, also called War of Texas Independence, war fought from October 1835 to April 1836 between Mexico and Texas colonists that resulted in Texas's independence from Mexico and the founding of the Republic of Texas (1836–45).
