The social, cultural and economic impact of the Mexican-American War continues to reverberate today.  The border that exists today is both a physical construct as well as a symbolic force dating back to the Treaty of Guadalupe Hidalgo of 1848 which was the formal ending to the war.  The Treaty effectively ceded the land from present day Texas to California along the Rio Grande/Bravo.  This paper will outline the contributing factors that led up to the war as well as the major events that brought it to a close.  More importantly, this paper will discuss how this war shaped the divergent paths these two neighboring countries would follow in the aftermath of the war.

In my opinion, the Mexican American War was one of the major events that led to the international dominance of the United States.  It has also played a major role in defining the relations between the two countries, with the U.S. controlling the major negotiations.

The American Southwest and the borderlands continue to struggle to define their identities, whether that be as American, Mexican, Native American, or the vast mixes that have evolved through the years.  Today, military conflict between the two countries has been replaced with ideological and political conflicts, but the fate of the United States and Mexico will forever be linked to the Treaty of Guadalupe Hidalgo and its vast impact.
