The purpose of this volume is to present, in harmony with the popular character of the series of which it is a part, brief sketches of some of the most familiarly named men and well-known incidents in the history of Western Civilization. The plan upon which the work is constructed assumes that the broad highway of historical narrative must be followed, however attractive may be the deviations from it that offer themselves at almost every page. The story told here has been told often before and very frequently the telling of it has come from master hands of literature. It is no easy task to reproduce, in a condensed form, material so often handled under much more generous limitations of space than are possible in this work. An attempt has been made, however, to escape from the bald tabular method of recording historical happenings that is almost certain to make a continuous reading of text-book history an impossibility. This must be the apology for many omissions; not only had the temptation to generalize to be resisted in favor of what might be called a process of arbitrary selection but many things are passed over in order to give appropriate emphasis in treating the matters which do actually appear in a narrative. If the volume had aimed at comprehensiveness, many more conquests would necessarily have been described and the list of characters and leaders in large numbers of military campaigns could of course be almost indefinitely enlarged. One can say in any case that though such additions will naturally suggest themselves, there is less doubt as to the claim of the leaders and events selected to appear with the prominence here assigned to them. If there has been a guiding principle in the selection, it may be found in the deliberate choice made of widely different periods of history. What may be called the group conquest is best illustrated in the case of the Ottoman Sultans and the Spanish Conquistadors, whereas the personal factor of the conqueror comes intensively forward in the chapters describing Alexander, Cæsar, and Napoleon. Although the military aspect of the history of conquest has not been neglected, the other less visible elements that ushered in great changes in history have not been omitted. In the preparation of the volume some attempt has been made to incorporate methods, points of view, and material that might not be accessible to those not concerned with the range of literature to which the ordinary student of history must appeal. It is only fair, therefore, to express my obligations to the following works. In the chapters dealing with ancient history, Beloch’s “Griechische Geschichte,” Delbrück’s “Kriegs Geschichte,” Kaerst’s “Geschichte des Hellenismus” and Heitland’s “History of the Roman Republic” have been largely used. In the chapter on Charles the Great, apart from Hodgkin’s well-known volumes “Italy and Her Invaders,” I have drawn upon Hartmann’s “Geschichte Italiens,” Ranke’s “Welt Geschichte,”
