This outline with the accompanying references is a revision and enlargement of An Outline for the History of Europe Since 1815 prepared in 1913 for the use of students at the Ohio State University. Like its predecessor it contains much fuller references on the period since 1870 than on the earlier years. Both Hazen's Europe Since 1915 and the second volume of Hayes's Political and Social History of Mod ern Europe have been followed in preparing the outline; and references to both these excellent books have been appended to most of the topics. Students should read one or both of these and at least one of the Additional References under each special topic. The purpose of the outline is not to provide a brief summary of the facts, predigested mental pabulum, as it were; but to provide a scheme of organization, to suggest to the student what he is to look for as he reads, and to teach liim to distinguish between essentials and non essentials. Hence the facts are not usually stated, but the student is left to work them out from his reference readings both in Hazen and Hayes and the Additional References.
