This historical commemoration of the Emancipation Proclamation came, shortly after September 11, 2001, as a venue for national celebration. The 140th anniversary of the Emancipation Proclamation celebrates the progression of the United States, and was reminiscent of a similar period in American history, following the Civil War. As momentum for the anniversary celebration grew, Americans joined in to participate across the United States.
