Causes of the Mexican War. Leading causes of the Mexican War included: Texan Annexation. Mexico had warned it would regard annexation as an act of war. When it took place, Mexico did not declare war, but broke diplomatic relations. The Boundary Dispute. Regardless of its status (was it an American state or a rebellious Mexican province?), the United States maintained that the southern border of Texas was formed by the Rio Grande, but Mexico argued that the traditional boundary was at the Nueces River farther north.
The Mexican war was mainly a war that President Polk wanted in effort to obtain more land for the United States. The people who wanted the war were mostly Democrats and Southerners. Southerners supported the war because they were in hope that more land would be acquired meaning more states would be admitted into the union as slave states. For this same reason the Whig Party opposed the war because they were abolitionists. Abolitionists opposed slavery so with the addition of new slave states, their hopes of making the U.S a slave free country were thwarted. Abolitionists such as Members from the Whig party stated that the war was unnecessary since we all ready had enough land.
