· Annexation of Texas by the U.S. and Mexico cuts diplomatic ties with U.S.
· President Polk, the president at the time, is a warmonger
· Manifest Destiny
· Boundary dispute in Texas region (U.S. claims Rio Grande river is border between the two countries and Mexico claims the Nauzes river as the border between the two countries)
Consequences or outcomes:
· War experience for Civil War generals
· More sectionalism (fight if to make new areas slave or free states)
· Uneasy reactions with Latin America since then
· CA gold rush starting in 1848
