The U.S. Library of Congress is set to open a new exhibit, "The Declaration’s Promise: A Revolutionary Idea," which explores the enduring influence of the Declaration of Independence on American democracy and its continuous reinterpretation throughout history.

The exhibit, based on the document's language and ideals, highlights how the Declaration, born from Enlightenment thought and revolutionary activism, transformed British colonists into American citizens. It emphasizes core principles like freedom of speech, religion, and equality, drawing on ideas from John Locke and Jean-Jacques Burlamaqui regarding natural rights and the "pursuit of happiness."

The Declaration's revolutionary nature is further demonstrated by its role in advocating for religious freedom, as seen in Moses Seixas's appeal to President George Washington and Washington's affirming response. Jefferson's copy of the Quran and an 1830 Book of Mormon will be on display as evidence of this tradition.

However, the exhibit also confronts the nation's failures to uphold these ideals, particularly regarding the enslavement of Africans. Abolitionists, including John Quincy Adams in the 1841 Amistad case, vigorously adopted the Declaration's language to demand rights. Similarly, the women's suffrage movement, with figures like Susan B. Anthony and Frederick Douglass, drew upon the document to assert claims for the franchise.

Walt Whitman's post-Civil War reflections in "Democratic Vistas" and Abraham Lincoln's Gettysburg Address are also featured, illustrating evolving visions of the Declaration's promises. The exhibit includes a nearly 55-foot petition from over 3,000 Black South Carolinians in 1865, appealing to Congress for voting rights, underscoring the ongoing struggle for equality despite Reconstruction's failures.

The Declaration's influence extended into the 20th century, inspiring the Civil Rights Movement, with John Lewis and Martin Luther King Jr. directly referencing its creed. Later movements for feminist, Native American, environmental, disability rights, and LGBTQ+ rights, exemplified by Frank Kameny's "Reminder Day" demonstrations, continued to invoke the Declaration's promise of liberty and the pursuit of happiness, demonstrating its persistent power in shaping American identity.
