A comprehensive, roughly chronological account of the peaks of the waves of migrations to America, from the forming of the nation to the present influx of Displaced Persons. Relating the American migrations to great movements in world history on the one hand, and to the national ideal of freedom on the other, the author discusses national and cultural migrations specifically -- the French, Dutch, Norwegians, Swedes, Germans, Irish, Chinese, Italians, Russians, Russian Jews, and the refugees and survivors of World War II. In each case, the reasons for leaving in great numbers, reception in America, contributions and adaptation are fully treated. There is also a chapter concerned with the Negro -- a special case since enslavement rather than freedom was offered them. Of necessity the attempts to place exact geographical location and establish ""national"" characteristics result in generalizations, but this is stimulating reading for all young Americans, at home or in the classroom.
