The National Constitution Center’s new permanent exhibit—the first in America devoted to exploring the constitutional debates from the Civil War and Reconstruction.

The exhibit features key figures central to the era—from Abraham Lincoln and Frederick Douglass to John Bingham and Harriet Tubman—and allows visitors of all ages to learn how the equality promised in the Declaration of Independence was finally inscribed in the Constitution by the 13th, 14th, and 15th Amendments, collectively known as the Reconstruction Amendments.

The 3,000-square-foot exhibit, entitled Civil War and Reconstruction: The Battle for Freedom and Equality, features over 100 artifacts, including original copies of the 13th, 14th, and 15th Amendments, Dred Scott’s signed petition for freedom, a pike purchased by John Brown for an armed raid to free enslaved people, a fragment of the flag that Abraham Lincoln raised at Independence Hall in 1861, and a ballot box marked “colored” from Virginia’s first statewide election that allowed black men to vote in 1867. The exhibit also features artifacts from the Civil War Museum of Philadelphia—one of the most significant Civil War collections in the country—housed at and on loan from the Gettysburg Foundation and The Union League of Philadelphia.
