Throughout the 400-year history of the United States, Americans have fought on battlefields both near and far, in clashes both large and small, alone and with allies at their sides. From the American Revolution of the late 18th century to the Iraq War in the early 21st, these conflicts have shaped the country’s policies, influenced its culture, defined its borders and cost thousands of lives.
