US History: Expansion in the 1800s

The National Archives and Records Administration (NARA) is the nation's record keeper. Of all documents and materials created in the course of business conducted by the United States Federal government, only 1%-3% are so important for legal or historical reasons that they are kept by us forever.

The National Museum of African American History and Culture is the only national museum devoted exclusively to the documentation of African American life, history, and culture. It was established by Act of Congress in 2003, following decades of efforts to promote and highlight the contributions of African Americans. To date, the Museum has collected more than 36,000 artifacts and nearly 100,000 individuals have become members. The Museum opened to the public on September 24, 2016, as the 19th and newest museum of the Smithsonian Institution.
