Declaration of Independence
The National Archives of the United States lists three documents as the “Founding Documents”: the Declaration of Independence, the Constitution, and the Bill of Rights.
Preamble to the Declaration of Independence
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.
The Declaration of Independence was ratified on July 4, 1776, creating a historical date that Americans observe every year as “Independence Day.” Internet Archive preserves many materials related to the Declaration including a souvenir copy, a full reading of the text from LibriVox, and more educational and informative items.

How has America celebrated past ‘-Ennial’ anniversaries
Since its founding America has always told stories about itself. These stories see hotspots every 50 years during the various ‘-ennial’ anniversaries dating back to 1826. Below is a selection of materials highlighting each past anniversary. To explore more, check out the broader collections linked within the relevant sections.
Semi-centennial (1826)
On its first 50-year anniversary, America still was in living memory of the American Revolution and the signing of the Declaration of Independence. Almost symbolically, two titans of that moment would pass on that very day: John Adams and Thomas Jefferson.
Jefferson was instrumental in drafting the original Declaration while Adams was one of the 56 signatories. Each man served as President during the earliest years of the United States’ history.
Within the Internet Archive’s collections is The John Adams Library at the Boston Public Library, containing many items related to Adams’ life. To learn more about the dual death of Adams and Jefferson please read more at the Library of Congress Blog.
The Semi-Centennial was commonly referred to as the American Jubilee at the time. The document below is a printed version of a speech given by Reverend William B. Johnson in 1826:
The speech traces a providential history of America from European settlement through the Revolution and into the nation’s first fifty years, reflecting the patriotic and deeply religious tone common to many Jubilee observances. It offers a snapshot of how Americans in 1826 understood their country’s past and envisioned its future.
Centennial (1876)
Following the American Civil War, the late 1860s and 1870s saw the passage of the Civil War Amendments (XIII, XIV, XV) that altered the civic order of the nation. As the 100th anniversary came about, the United States hosted the Centennial Exposition in Philadelphia. Explore more from this moment in our collections.

This map of the United States, published by cartographer J.A. Caldwell around the time of the nation’s Centennial celebrations in 1876, reflects how Americans visualized their country at its 100th anniversary.

Sesquicentennial (1926)

This recording comes from the United States Marine Band.
Created for the 1926 National Sesquicentennial Exposition in Philadelphia, this booklet explained the United States Public Health Service’s responsibilities through photographs and descriptions of medical practices.
