The correct answer is Mexican-American War
The Mexican-American War took place between the United States and Mexico from 1846 to 1848, and was motivated by the American ambition over territories that originally belonged to the Mexicans. This conflict was one of the stages of the “westward march,” a process of territorial expansion undertaken by the United States during the nineteenth century.
