A peaceful march in protest of racial injustice set out from Selma, Ala., on March 7, 1965, but was met with violent resistance from local law enforcement in an event that became known as "Bloody Sunday."
Civil rights demonstrators planned to march to the state capital in Montgomery to bring attention to the legal barriers set up to prevent African Americans from exercising their right to vote and to police violence following the death of Jimmie Lee Jackson, a 26-year-old church deacon, in Marion.

Alabama's segregationist Gov. George Wallace opposed the march and ordered state troopers to put a stop to it. Law enforcement deployed tear gas and used clubs and to attack the marchers.
The events of "Bloody Sunday" were captured on television cameras, shocking and outraging the American public. Over the next two days, demonstrations in support of the marchers were held in dozens of cities across the country.
Just over a week later, President Lyndon B. Johnson introduced legislation into Congress that would become the 1965 Voting Rights Act and called the events in Selma a turning point in the civil rights movement.
John Lewis helped lead the Selma march
Before his days serving in the U.S. Congress, John Lewis was the chairman of the Student Nonviolent Coordinating Committee.
He and Martin Luther King Jr.'s colleague, Hosea Williams, helped lead the peaceful march from Selma on "Bloody Sunday" while King was set to join them later in the day.
However, when Lewis, Williams and some 600 demonstrators arrived at the Edmund Pettus Bridge that stretched across the Alabama River and out of Selma, they faced a force of lawmen that included sheriff's deputies, dozens of state troopers and a deputized posse.
The lawmen refused to speak with the demonstrators and ordered them to disperse before violently beating and chasing the marchers.
Lewis was struck in the head and hospitalized along with dozens of other marchers.
America sees 'Bloody Sunday' on TV
The brutal assault was broadcast to the homes of millions of Americans who were watching ABC's telecast of "Judgment at Nuremburg" (1961), a film about the prosecution of Nazi war criminals.

News anchor Frank Reynolds interrupted the film to show the footage from the march.
The footage outraged Americans and broadened support for the marchers' cause.
Voting Rights Act of 1965
The Voting Rights Act, regarded as one of the most extensive pieces of civil rights legislation in U.S. history, helped overcome the legal barriers imposed at the state and local levels that prevented Black Americans from exercising their right to vote.
President Lyndon B. Johnson introduced the legislation into Congress on March 15, 1965.
The legislation would suspend literacy tests required for African Americans to determine voter eligibility and challenged the use of poll taxes when signed into law on Aug. 6.
The Road to Montgomery
On March 21, King led thousands of marchers out of Selma to Montgomery after a judge ruled that Wallace could not legally stop the demonstrators.
Swelling to numbers over 25,000, the marchers were protected by thousands of Alabama National Guardsmen, U.S. Army soldiers, federal marshals and FBI agents under the order of Johnson.
