1776 Document

The Declaration of Independence

Thomas Jefferson & the Continental Congress

"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 origin point — the founding promise every later generation would claim, challenge, and reinterpret.

1848 Document

Declaration of Sentiments

Elizabeth Cady Stanton, Seneca Falls

"We hold these truths to be self-evident: that all men and women are created equal..."

The first great reinvention of the Declaration — women's rights claimed in the founding's own words.

1852 Speech

"What to the Slave Is the Fourth of July?"

Frederick Douglass, Rochester

"This Fourth of July is yours, not mine. You may rejoice, I must mourn..."

Douglass turns the founders' words into a fierce indictment of a nation celebrating liberty while enslaving millions.

1863 Speech

The Gettysburg Address

Abraham Lincoln

"Four score and seven years ago our fathers brought forth on this continent a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal."

Lincoln re-founds the nation on the Declaration's promise of equality — and makes it the war's meaning.

1876 Document

Declaration of Rights of the Women of the United States

Susan B. Anthony, Centennial, Philadelphia

"We ask justice, we ask equality, we ask that all the civil and political rights that belong to citizens of the United States be guaranteed to us and our daughters forever."

Delivered at the nation's 100th birthday — proof that anniversaries become moments of reckoning over the Declaration.

1963 Speech

"I Have a Dream"

Martin Luther King Jr., March on Washington

"When the architects of our republic wrote the magnificent words of the Constitution and the Declaration of Independence, they were signing a promissory note to which every American was to fall heir."

King casts the Declaration as a check America has refused to cash — the most famous modern invocation of its promise.

1963 Letter

Letter from Birmingham Jail

Martin Luther King Jr.

"We will win our freedom because the sacred heritage of our nation and the eternal will of God are embodied in our echoing demands..."

From a jail cell, King anchors the struggle for justice in the nation's founding ideals.

2004 Speech

Democratic National Convention Keynote

Barack Obama

"We hold these truths to be self-evident, that all men are created equal. That they are endowed by their Creator with certain inalienable rights, that among these are life, liberty and the pursuit of happiness."

More than two centuries on, the Declaration's self-evident truths remain the language Americans reach for to define the nation.
