Building the American Republic combines centuries of perspectives and voices into a fluid narrative of the United States. Throughout their respective volumes, Harry L. Watson and Jane Dailey take care to integrate varied scholarly perspectives and work to engage a diverse readership by addressing what we all share: membership in a democratic republic, with joint claims on its self-governing tradition. It will be one of the first peer-reviewed American history textbooks to be offered completely free in digital form. Visit buildingtheamericanrepublic.org for more information. The American nation came apart in a violent civil war less than a century after ratification of the Constitution. When it was reborn five years later, both the republic and its Constitution were transformed. Volume 2 opens as America struggles to regain its footing, reeling from a presidential assassination and facing massive economic growth, rapid demographic change, and combustive politics. The next century and a half saw the United States enter and then dominate the world stage, even as the country struggled to live up to its own principles of liberty, justice, and equality. Volume 2 of Building the American Republic takes the reader from the Gilded Age to the present, as the nation becomes an imperial power, rethinks the Constitution, witnesses the rise of powerful new technologies, and navigates an always-shifting cultural landscape shaped by an increasingly diverse population. Ending with the 2016 election, this volume provides a needed reminder that the future of the American republic depends on a citizenry that understands-and can learn from-its history.
