National Museum of American History

Through incomparable collections, rigorous research, and dynamic public outreach, we explore the infinite richness and complexity of American history. We help people understand the past in order to make sense of the present and shape a more humane future.

The National Museum of American History collects and preserves more than 3 million artifacts—all true national treasures. We take care of everything from the original Star-Spangled Banner and Abraham Lincoln’s top hat to Dizzy Gillespie’s angled trumpet and Dorothy’s ruby slippers from The Wizard of Oz. Our collections form a fascinating mosaic of American life and comprise the greatest single collection of American history.
