The Mexican War, which resulted in a vast expansion of the national domain, has had a small place in the annals of American history. Treated as either the climax to the great expansionist movement of the 1840's, or as the first steop leading to civil war, the war with Mexico has been studied as an adjunct ot these more popular theses. Probbaly partial blame can be p;aced on the abolitionist writers who savagely condemned the war as part of a great slave conspiracy which ultimately brought on the American Civil War... It is the purpose of this thesis to trace the varied and changing interprotations that American historians have developed in trying to understand the causes of the Mexican War. These interpretations have not been studied in a vacuum; an effort has been made to account for these changes in interpretation by trying to understand the various "climates of opinions" that have produced then. The social, political, and economic forces involved one necessarily only be suggested. Human nature precludes mathematical precision in understanding direct causation.
