On March 15, 1965, Lyndon Baines Johnson addressed a joint session of Congress to push for the Voting Rights Act. In his speech, Johnson not only advocated policy, he borrowed the language of the civil rights movement and tied the movement to American history.

Mr. Speaker, Mr. President, Members of the Congress:

I speak tonight for the dignity of man and the destiny of democracy.

…

At times history and fate meet at a single time in a single place to shape a turning point in man’s unending search for freedom. So it was at Lexington and Concord. So it was a century ago at Appomattox. So it was last week in Selma, Alabama.

There, long-suffering men and women peacefully protested the denial of their rights as Americans. Many were brutally assaulted. One good man, a man of God, was killed.

There is no cause for pride in what has happened in Selma. There is no cause for self-satisfaction in the long denial of equal rights of millions of Americans. But there is cause for hope and for faith in our democracy in what is happening here tonight.

For the cries of pain and the hymns and protests of oppressed people have summoned into convocation all the majesty of this great Government–the Government of the greatest Nation on earth.

Our mission is at once the oldest and the most basic of this country: to right wrong, to do justice, to serve man.

In our time we have come to live with moments of great crisis. Our lives have been marked with debate about great issues; issues of war and peace, issues of prosperity and depression. But rarely in any time does an issue lay bare the secret heart of America itself. Rarely are we met with a challenge, not to our growth or abundance, our welfare or our security, but rather to the values and the purposes and the meaning of our beloved Nation.

The issue of equal rights for American Negroes is such an issue. And should we defeat every enemy, should we double our wealth and conquer the stars, and still be unequal to this issue, then we will have failed as a people and as a nation.

…

This was the first nation in the history of the world to be founded with a purpose. The great phrases of that purpose still sound in every American heart, North and South: “All men are created equal”—“government by consent of the governed”—“give me liberty or give me death.” Well, those are not just clever words, or those are not just empty theories. In their name Americans have fought and died for two centuries, and tonight around the world they stand there as guardians of our liberty, risking their lives.

Those words are a promise to every citizen that he shall share in the dignity of man. This dignity cannot be found in a man’s possessions; it cannot be found in his power, or in his position. It really rests on his right to be treated as a man equal in opportunity to all others. It says that he shall share in freedom, he shall choose his leaders, educate his children, and provide for his family according to his ability and his merits as a human being.

To apply any other test–to deny a man his hopes because of his color or race, his religion or the place of his birth–is not only to do injustice, it is to deny America and to dishonor the dead who gave their lives for American freedom.

…

To those who seek to avoid action by their National Government in their own communities; who want to and who seek to maintain purely local control over elections, the answer is simple:

Open your polling places to all your people.

Allow men and women to register and vote whatever the color of their skin.

Extend the rights of citizenship to every citizen of this land.

…

So I ask you to join me in working long hours–nights and weekends, if necessary–to pass this bill. And I don’t make that request lightly. For from the window where I sit with the problems of our country I recognize that outside this chamber is the outraged conscience of a nation, the grave concern of many nations, and the harsh judgment of history on our acts.

But even if we pass this bill, the battle will not be over. What happened in Selma is part of a far larger movement which reaches into every section and State of America. It is the effort of American Negroes to secure for themselves the full blessings of American life.

Their cause must be our cause too. Because it is not just Negroes, but really it is all of us, who must overcome the crippling legacy of bigotry and injustice.

And we shall overcome.

…

My first job after college was as a teacher in Cotulla, Texas, in a small Mexican-American school. Few of them could speak English, and I couldn’t speak much Spanish. My students were poor and they often came to class without breakfast, hungry. They knew even in their youth the pain of prejudice. They never seemed to know why people disliked them. But they knew it was so, because I saw it in their eyes. I often walked home late in the afternoon, after the classes were finished, wishing there was more that I could do. But all I knew was to teach them the little that I knew, hoping that it might help them against the hardships that lay ahead.

Somehow you never forget what poverty and hatred can do when you see its scars on the hopeful face of a young child.

I never thought then, in 1928, that I would be standing here in 1965. It never even occurred to me in my fondest dreams that I might have the chance to help the sons and daughters of those students and to help people like them all over this country.

But now I do have that chance—and I’ll let you in on a secret—I mean to use it. And I hope that you will use it with me.
