Thus the following pages utterly fail of their purpose if they do not picture the background of congressional and sectional conflicts during the period from Andrew Jackson to Abraham Lincoln. But, to be sure, in so brief a book all the contributing elements of the growing national life cannot be fully described or even be mentioned. Still, it is the hope of the author that all the greater subjects have been treated. What has been omitted was omitted in order to devote more space to what seemed to be more important, not in order to suppress what some may consider to be of primary significance. Three hundred short pages for the story of the great conflict which raged from 1828 to 1865 do not offer much latitude for explanations and diversions along the way. Nor is it possible for any one to describe this conflict satisfactorily even to all historians, to say nothing of the participants who still live and entertain the most positive and contradictory convictions. Hence one must present one's own narrative and be content if open-mindedness and honesty of purpose be acknowledged. The book is intended for the maturer students in American colleges and universities and for readers who may be desirous of knowing why things happened as they did as well as how they happened. And by the employment of collateral readings suggested in the short bibliographies at the close of each chapter, both the college student and the more general reader may find his way through the labyrinth of conflicting opinion and opposing authorities which make up the body of our written history. To make this task easier some twenty-five maps have been prepared and inserted at the appropriate places in the text. These maps, perhaps one might say photographs of social or economic conditions, attempt to present the greater sectional and industrial groups of "interests" which entered into the common life of _ante-bellum_ times. They treat party evolution, economic development, and social antagonisms in a way which, it seems to the author, should help the reader to a better understanding of things than would be possible by the simple narrative. For permission to use the maps on pages 291, 313, and 327 the author expresses his thanks to the publishers of _The Encyclopedia Americana_.
