"How did that happen?" students wonder about their past. America’s History provides a clear explanation. Instructors rely on America’s History to help them teach that history matters — this means helping their students understand not only what happened, but also why. For the new, sixth edition, the authors took a hard look at all aspects of their text, considered what worked and what didn’t, and crafted a broad revision plan that demonstrates, once again, their unmatched commitment to America’s History. The hallmark of the revision is a thorough reconsideration of the post-1945 period that incorporates new scholarship and makes sense of the recent past, but America’s History, Sixth Edition offers much more. This includes additional narrative changes in both volumes, a new in-text feature program based on written and visual primary documents in every chapter, and a host of new and improved pedagogic features. With its clear exposition, insightful analysis and in-text sources, America’s History, gives instructors and students everything they need.
