A Review of the Studies on the Nineteenth-Century American Empire in the American Academia
For a long time,the American academia has avoided discussing the existence of"empire"and imperialism in American history.Not until in the 1960s did this lack of attention start to change.Driven by social backgrounds and academic currents,American scholars became increasingly aware of the imperial nature of the United States and society in the nineteenth century.As a result,studies on nineteenth-century American Empire delve into the imperialistic aspects of the United States'continental expansion and overseas activities,covering various aspects like diplomatic activities,capital,commodities and personnel flows,domestic policies,social currents and norms,and family relations.The study of this topic has expanded the scope of American historical studies,enhanced its critical nature,and facilitated comparison between the United States and its European counterpart,offering a valuable historical approach that warrants further research.
