Now in its third edition, American Military History examines how a country shaped by race, ethnicity, economy, regionalism, and power has been equally influenced by war and the struggle to define the role of a military in a free and democratic society. Organized chronologically, the text begins at the point of European conflict with Native Americans and concludes with military affairs in the early 21st century, providing an important overview of the military’s role on an international, domestic, social, and symbolic level. The third edition is fully updated to reflect recent developments in military policy and the study of military history and war and society, thus providing students a foundational understanding of the American military experience. This book will be of interest to students of American history and military history. It is designed to allow instructors flexibility in structuring a course.
