Finally, President Johnson decided to send soldiers from the United States Army and the Alabama National Guard to protect the marchers. From March 21 to March 25, the marchers walked along the "Jefferson Davis Highway" from Selma to Montgomery. On March 25, 25,000 people entered Montgomery. Martin Luther King gave a speech called "How Long? Not Long" at the Alabama State Capitol. He told the marchers that it would not be long before they had equal rights, "because the arc of the moral universe is long, but it bends toward justice."
