What war resulted from what John Tyler wanted the southern states to do?

John Tyler, the 10th President of the United States, was a proponent of westward expansion and the annexation of Texas, which was seen as a means to strengthen the southern states and their interests. His push for Texas annexation contributed to rising tensions between the North and South over the issue of slavery. This tension ultimately culminated in the Mexican-American War (1846-1848), as the U.S. sought to expand its territory, which was closely tied to the interests of the southern states. The war further intensified the sectional divisions that would eventually lead to the Civil War.
