The Promise of Liberty: Words That Shaped a Nation

In celebration of America’s 250th anniversary, experience this full-floor exhibition in the historic 1868 A.A. Thomson & Co. building and journey through the nation’s founding ideas—tracing how they have evolved over time through rare defining documents and pivotal moments in history. If the United States has a mission statement, it was written 250 years ago in the Declaration of Independence: “Life, Liberty, and the pursuit of Happiness.” As you explore the fascinating and unique exhibition, you see how this promise—established in 1776—was never fully realized and remains an aspiration we continue to pursue today.

Throughout the gallery, you encounter some of the nation’s most iconic 18th century documents, including the Declaration of Independence, the United States Constitution, and the Bill of Rights. Alongside these are exceptional handwritten pages from an undelivered inaugural address by George Washington, as well as remarkable 19th and 20th century treasures such as the Emancipation Proclamation and an advance copy of Martin Luther King, Jr.’s “March on Washington” speech. In it, King describes the Declaration of Independence and Constitution as “a promissory note to which every American was to fall heir.” Together, these extraordinary artifacts reveal how the pursuit of freedom has been redefined across generations.

Through rarely-seen documents and ephemera, you discover key moments that pushed the nation closer to equality—from the fight for religious freedom and the abolition of slavery to the movement for women’s suffrage. Extraordinary pamphlets and treaties, one-of-a-kind personal correspondence from notable historical figures, striking broadsides, and first printings of landmark texts bring these pivotal episodes to life and connect you to the people who shaped them.

Due to the sensitive nature of the materials on display and to make sure all visitors have the best possible experience, the number of people allowed in the exhibition at one time is limited. Admission for ticket holders is on a first-come, first-served basis.
