Celebrate 250 years of American history--and witness the nation's decade-by-decade evolution--in this gorgeously illustrated volume featuring 700 Smithsonian objects. The 250th anniversary of the United States marks a major milestone, representing two-and-a-half centuries of upholding democracy, building communities, defining freedom, and working to become a more perfect union. In The Promise of Our Nation, Smithsonian curators share aspirational stories that have shaped the nation in chapters representing each decade from the 1770s to the 2020s. Smithsonian objects help bring each decade to life and personalize the history, from George Washington's sword (1770s) to an African American volunteer fire company badge (1860s) to Marian Anderson's attire worn at her Lincoln Memorial concert (1930s) to Space Shuttle Discovery (1990s). Each chapter begins with a timeline of major events and census data, followed by an essay that considers American history through a meaningful and often unexpected lens. Gorgeous full spreads feature spotlight objects that tell decade-specific stories and offer important insight into each decade and the American story. The nation's semiquincentennial is an opportunity to reflect on the past with care and curiousity. The scope of American history is vast, but The Promise of Our Nation distills it into compelling narratives that speak to the strength and aspirations of the American people and inspire optimism for what comes next.
