This thesis examines the trends in historical interpretation concerning the coming of the American Civil War. The main body of works examined were written between 1950 and 1976, beginning with Allan Nevins' Ordeal of the Union and concluding with David M. Potter's The Impending Crisis, 1848-1861. It also includes a brief survey of some works written after 1976. The main source for discovering the materials included were the bibliographies of both monographs and general histories published during and after the period 1950-1976. Also, perusal of the contents and book review sections of scholarly journals, in particular the Journal of Southern History and Civil War History, was helpful in discovering sources and placing works in a time chronology for the thesis narrative.
