The Smithsonian's National Museum of American History dedicates its collections and scholarship to inspiring a broader understanding of our nation and its many peoples. We create opportunities for learning, stimulate imaginations, and present challenging ideas about our country’s past. The Museum 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.
