Fought between the United States and Mexico, it resulted in significant territorial changes and marked a critical turning point in the relations between these two nations.

By delving into these aspects, this essay aims to shed light on how the Mexican-American War was justified as a means to protect American interests, expand the nation's territory, and assert its manifest destiny.
