Months before Martin Luther King Jr.'s "I Have a Dream" declaration galvanized a quarter-million people at the 1963 March on Washington, Rustin was planning all the essential details to keep the crowd orderly and engaged. A Quaker, and a pacifist, Rustin served as chief strategist for King's march over the objections of some leaders, but was kept mostly in the background with some organizers considering him a liability. Notably, he was gay in an era when same-sex relations were widely reviled in American society. He died in 1987, and is sometimes forgotten in civil rights history. (AP Photo/A. Camerano)

Bayard Rustin In this Aug. 1, 1963 black-and-white photo, Bayard Rustin, leader of the "March on Washington" speaks at the National Headquarters. Months before Martin Luther King Jr. declared "I Have a Dream" to galvanize a crowd of thousands, Rustin was planning all the essential details to make the 1963 March on Washington a success. Rustin, who died in 1987, is sometimes forgotten in civil rights history. He had been an outcast. He was a Quaker, a pacifist who opposed the Vietnam war and had flirted with communism. And he was gay. Fifty years later, Rustin's legacy is a key part of the march anniversary. Civil rights leaders plan an unprecedented inclusion of gay, lesbian, bisexual and transgender people this month as part of a larger movement calling for equal rights for all.

It wasn't until the 1960s civil rights movement, exemplified by the historic march, that new laws began strengthening the federal role in civil right protection. Now, the Justice Department is expected to pursue civil rights prosecutions. But in many cases of inflamed racial passions, federal prosecutors don't find the evidence needed to support civil rights charges. (AP Photo, File)
