"In 2013, the anniversary of two key American milestones will be celebrated in a new exhibition. Changing America: The Emancipation Proclamation, 1863 and the March on Washington, 1963, presented jointly by the National Museum of African American History and Culture and the National Museum of American History. Separated by 100 years of historical events, the two anniversaries present stories of people demanding justice and ultimately having a major impact on the American experience. With objects ranging from Nat Turner's Bible, the exhibition showcases the growing National Museum of African American History and Culture collections and the diversity of artifacts that tell the story of the African American experience. ...  Visitors will be able to see in this exhibition the long stretch of events that fostered social justice in America. ...  Scheduled to open on December 14, 2012, the exhibition will be on view through September 15, 2013, in the National Museum of African American History and Culture temporary gallery on the second floor of the National Museum of American History. It will be accompanied by a new website and a series of public programs and lectures that invite visitors to examine the social and political currents that shaped these events and to delve more deeply into their meaning to contemporary Americans."
