While, therefore, great care has been taken, in the following pages, to attribute to the Southern leaders and the Southern people sincerity of purpose in their views and their acts, while their ideas and their reasoning have been, I think, duly appreciated, and patiently explained, while the right has been willingly acknowledged to them and honor accorded them whenever and wherever they have had the right and have merited honor, and while unbounded sympathy for personal suffering and misfortune has been expressed, still not one scintilla of justification for secession and rebellion must be expected. The South must acknowledge its error as well as its defeat in regard to these things, and that, too, not with lip service, but from the brain and the heart and the manly will, before any real concord in thought and feeling, any real national brotherhood, can be established. This is not too much to demand, simply because it is right, and nothing can be settled, as Mr. Lincoln said, until it is settled right. Any interpretation of this period of American history which does not demonstrate to the South its error will be worthless, simply because it will not be true; and unless we are men enough to hear and accept and stand upon the truth, it is useless to endeavor to find a bond of real union between us. In a word, the conviction of the South of its error in secession and rebellion is absolutely indispensable to the establishment of national cordiality; and the history of this period which fails to do this will fail in accomplishing one of the highest works of history, the reconciliation of men to the plans of Providence for their perfection. I have not, in the following pages, undertaken to treat _all_ of the events of our experience from 1816 to 1860. The space allowed me would not admit of that. And even if it had, I still would have selected only those events which, in my opinion, are significant of our progress in civilization, and, as I am writing a political history, only those which are significant of our progress in political civilization. The truthful record, connection, and interpretation of such events is what I call history in the highest sense, as distinguished from chronology, narrative, and romance. Both necessity and philosophy have confined me to these. I cannot close these prefatory sentences without a word of grateful acknowledgment to my friend and colleague, Dr. Harry A. Cushing, for the important services which he has rendered me in the preparation of this work. JOHN W. BURGESS. 323 WEST FIFTY-SEVENTH STREET, NEW YORK CITY. JANUARY 22, 1897. CONTENTS PAGE CHAPTER I.
