"In clean, well-paced prose, Dawley sets the successes--and failures--of early American progressives ... against the backdrop of a complicated postwar world... This is an especially timely book, given the tense state of world affairs."--Publishers Weekly "Changing the World is an ambitious and accessible book... [It] will provide students, scholars, and the wider public with an engaging, wide-ranging synthesis of a complex and pivotal period."--Michael E. Latham, Reviews in American History "One does not have to agree with all of the author's points to find this a stimulating, thoughtful examination of 20th-century progressivism."--Choice "Bancroft Prize-winning historian, Alan Dawley has once again produced a tour de force... Vividly written, this book is filled with fresh insights on the Progressive Era, from its politics and diplomacy to its architecture."--John Whiteclay Chambers II, Pennsylvania Magazine of History and Biography
