March 1965 marked a pivotal time for the U.S. civil rights movement, when the Rev. Martin Luther King Jr. led demonstrators to protest discrimination against black Americans in Alabama who had been denied the right to vote. The march from Selma to the state capital began three times before the demonstrators were finally able to finish it.
The first attempt took place March 7, 1965, when 600 demonstrators were attacked by state and local police with weapons and tear gas as they reached the Edmund Pettus Bridge in Selma, injuring 17 protesters in what came to be known as "Bloody Sunday."
It became national news when televisions across the country displayed images of bloodied and severely injured marchers.
The second march, March 9, resulted in 2,500 protesters turning around after crossing the main bridge because of the restraining order a federal district court judge issued barring the march from taking place until he could hold additional hearings later in the week.
The third march started March 16, when the restraining order was lifted after a judge ruled in favor of the marchers, citing their First Amendment right to protest anywhere, even in Alabama. They started March 21 and walked an average of 10 miles a day on their 54-mile trek. The National Guard and the FBI looked on as the march proceeded to Montgomery. About 25,000 people marched to the steps of the Alabama State Capitol Building in Montgomery March 25 when King delivered the speech "How Long, Not Long."
