On the morning of March 7, 1965, approximately six hundred people walked two by two out of Brown Chapel A.M.E. Church in Selma, Alabama, and turned east toward the Edmund Pettus Bridge. They carried no weapons. They sang no songs. John Lewis, twenty-five years old and already a veteran of sit-ins and Freedom Rides that had fractured his skull at least once before, walked at the front alongside Hosea Williams. When they crested the bridge’s arc, they saw what was waiting for them on the other side: a solid line of Alabama state troopers in blue helmets, some on horseback, gas masks clipped to their belts. Behind the troopers stood Sheriff Jim Clark’s mounted posse — men who had already ridden horses into church congregations and beaten parishioners with clubs. A state trooper with a bullhorn gave the marchers two minutes to turn around. They did not turn around. They knelt to pray.
What happened in the next few minutes was broadcast into living rooms across America and changed the course of American law. Troopers waded into the crowd with clubs and tear gas. Horsemen rode directly into the kneeling marchers. Lewis took a nightstick blow to the skull that fractured his cranium. Amelia Boynton Robinson, one of the movement’s anchors in Selma, was beaten unconscious and left in the road. A photograph of her limp body, face bloodied, appeared on the front pages of newspapers in every major American city the next morning. ABC News interrupted its broadcast of “Judgment at Nuremberg” to show footage of the assault. The irony of that interruption — a film about the legal apparatus of a genocidal state, cut away from to show American law enforcement attacking unarmed Black citizens on a bridge — was not lost on anyone.
President Lyndon Johnson watched the footage from the White House. Eight days later, he stood before a joint session of Congress and delivered what many historians consider the most powerful speech of his presidency. “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,” he said. “So it was at Lexington and Concord. So it was a century ago at Appomattox. So it was last week in Selma, Alabama.” Then, quoting directly from the anthem of the civil rights movement, the President of the United States said into a microphone before the full Congress: “We shall overcome.”
But to understand why those six hundred people were on that bridge, and why what happened to them shook a nation, you have to go back not eight days but a hundred years — to the moment the United States first promised Black citizens the right to vote, and the generations of calculated brutality that followed that promise.
The Fifteenth Amendment and Its Betrayal
The Fifteenth Amendment, ratified in February 1870, was blunt: the right of citizens to vote shall not be denied or abridged on account of race, color, or previous condition of servitude. Frederick Douglass called it “the most important event” since the Emancipation Proclamation. And for a brief period, it functioned. During Reconstruction, Black men exercised the franchise in force. Between 1870 and 1877, sixteen Black men served in Congress; more than six hundred served in state legislatures across the South; hundreds more held local offices as sheriffs, tax collectors, judges, and aldermen. Mississippi sent two Black men to the United States Senate — Hiram Revels and Blanche Bruce — and would not send another for over a hundred years. The brief, luminous experiment of Reconstruction demonstrated what Black political participation could produce when it was protected by federal force.
The counterrevolution was swift and comprehensive. When federal troops withdrew from the South in 1877 as part of the Compromise that ended Reconstruction, former Confederate states began systematically dismantling everything that had been built. The instruments of disenfranchisement were so ingeniously layered that they would take nearly ninety years and the full weight of federal law to dismantle. Poll taxes — flat fees required of every voter — were calibrated to exactly what a Black sharecropper living in the cotton economy could not afford to pay, since sharecroppers were often paid in credit against a company store rather than in cash at all. Literacy tests, administered entirely at the discretion of white registrars, required Black applicants to read and interpret passages from state constitutions, sometimes demanding recitation from memory; the same registrars who failed Black professors and schoolteachers would register illiterate white men without a second glance. Mississippi’s constitution required applicants to “give a reasonable interpretation” of any section a registrar chose — a standard that, applied at a registrar’s whim, was impossible to meet and impossible to appeal.
Grandfather clauses exempted men from literacy and property requirements if their grandfather had voted before 1867 — an explicit mechanism to include white men while excluding Black men whose grandfathers had been legally prohibited from voting. White primaries, which the Democratic Party operated as private organizations throughout the South, excluded Black voters entirely from the only elections that actually matter
