War has always been a companion of humanity. History has shown us different reasons for war like political, social or economic reasons. Palo Alto battlefield witnessed of the first Mexican-American war fighting to expand territories. Even if the history of this battle is faded, because we pay more attention to other national or international war, this is part of both American and Mexican history. Furthermore, Palo Alto battlefield is considered the only park in the United States National Parks system that is focus on the U.S-Mexican War. As a Mexican living in the United States, I thought it was interesting to look for a park that was related to my country; physical, social and economic relations between these countries are part of who we are.
