Preface to the First Edition
This Epitome of History itself has a long and interesting history. More than seventy years ago Dr. Karl Ploetz, in his time a well-known German teacher, published an Auszug aus der alten, mittleren und neueren Geschichte, intended as a factual handbook for the use of students and for the convenience of the general reader. That his compilation filled a real need is attested by the fact that within a few years it went through seven editions, and by the further fact that to date more than twenty editions have appeared in Germany, revised and edited by noted scholars. The book has easily held its own despite competition of numerous similar books.  1
Ploetz's Epitome was translated into English by William H. Tillinghast and published by Houghton Mifflin Company in this country in 1883. The translator, recognizing that the original was designed particularly to meet the needs of the German student and that therefore the history of central Europe was weighted against the history of France, England, and America, took the opportunity to enlarge a number of sections and to add others. No less a scholar than Edward Channing contributed the new sections on modern England and the United States. Furthermore, Tillinghast first added brief sections on the Middle and Far Eastern countries, which had been completely omitted from the German version. The book appeared under the title An Epitome of Ancient, Medieval, and Modern History, and proved so popular that no less than twenty-four printings were necessary before 1905. Occasional revisions were made and in 1915 the title was changed to A Handbook of Universal History.  2
Since historical knowledge and historical conceptions are notoriously fluid, it is not to be wondered at that even so sound and reliable a book as the old Ploetz-Tillinghast Epitome should ultimately have fallen behind the times. After the First World War the publishers therefore commissioned Dr. Harry Elmer Barnes to overhaul the book and bring it up to date. The new editor, with a number of collaborators, left the kernel of the old work (the Greek and Roman history, the medieval sections, and the early modern parts) as it was, judging quite rightly that in the large it was not so badly out of line as to justify rewriting and resetting. But the sections dealing with the early Near East, of which little was known in Ploetz's day, were completely redone, and a great deal of material on the period from 1883 to 1923 was added. The Epitome, thus revised, was published in 1925 as A Manual of Universal History. Like the preceding versions it has been widely used by students and laymen alike.  3
But despite revisions of one kind or another, it became increasingly clear that sooner or later the original book would require drastic changes if it were to keep abreast of modern knowledge and meet contemporary requirements. It stands to reason that in seventy years our command of the facts and our views of even those subjects best treated by Ploetz and Tillinghast have changed substantially. Above all, the past fifty years have witnessed the expansion of western influence over the entire globe and, as a result, there is now a much greater need to know something of the past of non-European countries and cultures, and a much livelier interest in formerly neglected fields. To fill the new requirements no amount of revision of the old book would do, for the original author wrote as a German and treated European history primarily as it touched his own country's develpment. Tillinghast attempted to give the English translation a somewhat more Anglo-American slant, and Dr. Barnes did what was humanly possible to adapt the old text to a more world-wide approach. But the point had been definitely reached where adaptations and adjustments would no longer suffice. The publishers therefore invited me to undertake a complete rewriting of the entire book, securing the aid of collaborators qualified to treat of special fields where it seemed desirable. It was my great good fortune to be able to interest fifteen of my colleagues to take over particular sections and to secure from them the most whole-hearted co-operation in what, after all, was an enterprise of some magnitude. Their names, with the sections for which they made themselves responsible, are listed above.  4
When embarking upon this project I still had hope that considerable parts of the old book might yet be salvaged and that a thoroughgoing revision would prove adequate for the ancient, medieval, and early modern sections. But it soon became apparent to all of us engaged in the work that the whole plan and approach required rethinking and that, consequently, there was but little use in trying to adhere to the old text. Here and there a few pages (thoroughly emended) have been retained, but they are relatively so few in number as to be hardly worth mentioning. Almost nothing of the substance of the old book remains; every single section has been gone over in thorough fashion, reduced or expanded and, above all, brought into line with present-day knowledge. Many other sections, naturally, have been newly written, so that I think we can honestly say that the book is no longer a manual of European history with some perfunctory reference to other countries, but genuine world history, in which the geographical divisions are dealt with on their merits.  5
In the course of rewriting we have, however, stuck by Ploetz's original conception. That is, we have tried to compile a handbook of historical facts, so arranged that the dates stand out while the material itself flows in a reasonably smooth narrative. Individual judgments have been kept in the background and divergent interpretations have been adduced only where they seem to be indispensable. The great diversity of type which had crept into the old book has been done away with and we have broken the uniformity of the print only by the use of small and capital boldface and very occasional employment of italics. The number of genealogical charts has been much increased: new tables have been added for some of the non-European dynasties and all charts have been brought up to date. Furthermore, a considerable number of maps has been included, not with the idea of supplying a complete historical atlas, but simply for the convenience of the user who, when he is checking one event or another, cannot be expected to have always at hand the necessary map material.  6
In the preface to the 1925 edition Dr. Barnes referred to the growing interest in non-political aspects of history and to his attempt to expand sections dealing with economic and cultural developments. Though deeply interested in these phases of history, Dr. Barnes felt obliged to recognize that the majority of those who would use the book would come seeking information on political, military, and diplomatic history and that therefore those angles would have to be primarily considered. I subscribe entirely to this view, but I take this opportunity to point out further that cultural history does not lend itself readily to the method of treatment upon which this particular work is based. The backbone of this book is chronology which, in the case of general economic trends, religious and artistic movements, and intellectual currents, is both hard to define and of relatively less significance. For methodological reasons, if for no other, we could therefore give but slight emphasis to these aspects of history. In addition we had to consider the further difficulties presented by space limitation: obviously anything like adequate treatment of literature, art, science, and economics would have taken us so far afield that the results could not possibly have been enclosed within two covers. In some sections the reader will find brief summaries of cultural activities, in others not; but in any case we offer them only for what they may be worth, as a matter of convenience, without any thought of sufficiency, much less exhaustiveness. And these remarks apply equally to the special sections at the beginning of the nineteenth century, entitled Social Thought and Social Movements, Scientific Thought and Progress, and Mechanical Inventions and Technical Achievements. 1 The material we adduce in these sections appeared to us indispensable for an understanding of nineteenth-century development. It cannot be suitably included under one country, for its application is general. We could not aim or hope for completeness; hence our only objective in these sections has been to bring together an irreducible minimum of pertinent information.  7
Each successive editor of this Handbook has come away from his task impressed with the difficulties of attaining accuracy in dealing with so vast a number of dates covering so wide a range of time and territory. I am no exception to the rule and am far from being arrogant enough to suppose that this new book is even more free from error than the old. There is some consolation, however, in the thought that we collaborators have all done what we reasonably could to guard against blunders and that, as a matter of fact, many dates are so uncertain or disputed that they will probably never be satisfactorily fixed.  8
The success of the Epitome of History over a period of more than two generations is ample proof of the need for a manual of this type. In the revised and extended form here presented, it ought to be more valuable than ever. Its use for students of history is obvious enough, but it ought to prove as helpful to many others. Students of the history of literature and of art should find a concise guide to political history a great boon and all readers of historical novels or biographies should welcome a book of reference to events of the past, to genealogical relationships, and so on. My own experience with the old book was that I used it more as I became better acquainted with it. Nothing would please me more than to have the new edition find a secure place on the shelves of all book-lovers.  9
In presenting the new Epitome I cannot refrain from expressing my profound gratitude to all the contributors and also to Professors Walter Clark and Vincent Scramuzza, to Professor Sterling Dow, Mr. Eugene Boardman, and to Miss Katharine Irwin for the ready help they gave in reading proof. My secretaries, Mrs. Elizabeth Fox and Mrs. Rosamund Chapman, took care of countless loose ends and deserve more than a little credit for whatever merit the book may have.  10
