| As a federal state,Sectionalism has played an important role in American diplomacy for a long time.The American South,as the country’s most self-conscious,coherent and long-lasting region,has an impact on American Foreign Policy that cannot be ignored and it has a more obvious influence on American foreign affairs in the Wilson government’s foreign policy on Mexico.At first,this paper points out the deep origin between the South and President Wilson from the aspect of the South and President Wilson’s "Southern factors".Then,based on the archives of Congress and the media at that time and combined with the research results of modern scholars,this paper analyzes the attitude and performance of the South in Wilson government’s policy towards Mexico,understands the relevant factors that affect the attitude of the South towards foreign policy,discusses the shaping of foreign policy by Sectionalism in American foreign affairs and attempts to analyse American diplomacy from the perspective of Sectionalism.The main content of this paper is composed of introduction,main text,and conclusion,in which the text is divided into three parts.The first part focuses on the situation of the South and Wilson’s strong "Southern colors".If we want to explore the South and the foreign policy of Wilson government in depth,we must focus on the close relationship between Wilson and the South America which is a guarantee of Wilson’s presidency and an important basis for the return of the South to the center of national affairs.The main political and economic backwardness of the South made the Democratic Party the most influential political party in the South.Wilson,who was born in the South,became a democratic presidential candidate in 1912,which made the Southern sectionalism and parties closely integrated.With the support of Southerners,Wilson won the presidential election and became another Southern president after the Civil War.It was a victory for the South and the basis for the South to do its best to support Wilson in the American policy on Mexican.Through the analysis of the South and President Wilson,this section summarizes the relevant factors that will affect the diplomatic attitude of the South,and will be verified in the following analysis.The second part focuses on the attitude of the South in the foreign policy of the Wilson government to the first government in the Mexican revolution,the Huerta government.Out of dissatisfaction with the way Huerta gained power,Wilson refused to recognize the Huerta regime,although the losses of Texas caused doubts about Wilson.But the vast majority of southerners still choose to defend their southern president,out of recognition of their president.Until the outbreak of the Tampico incident,driven by the intensely patriotic tradition,southerners turned to call for troops to intervene in Mexico,which also contributed to Wilson’s change in the foreign policy of the Huerta regime to a certain extent and the Southerners helped Wilson achieve the implementation of Huerta military plan of intervention by voting.The third part analyzes the southern attitude of Wilson government to the foreign policy of the Mexican Carranza regime.Just like the relationship with the Huerta regime,the Southerners also played an important role in the Wilson government’s diplomatic relations with the Carranza regime.It was precisely because of a series of incidents on the U.S.-Mexico border that Southerners continued to demand the United States to intervene in Mexico,which also prompted the Wilson government send expeditionary troops into Mexico.In the presidential election of 1916,for the sake of partisan politics,the South strongly supported peaceful consultations with the Carranza regime to ensure Wilson won the election. |
