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 only cause of the war was that the South was invaded and responded to Northern aggression. I respectfully disagree with those who claim that the War Between the States was fought over slavery or that the abolition of slavery in the Revolutionary Era or early Federal period would have prevented war.
