"A tactic is not a movement. A lot of people got excited by the tactics, but they didn't have a second act."
People remember the March on Washington because it did have a second act. Civil rights leaders used the political pressure generated by the march and the subsequent assassination of President John F. Kennedy to pressure Congress to pass the Civil Rights Act of 1964 and the Voting Rights Act of 1965, historians say.
Still, they were also willing to compromise. And compromise is not glamorous. Failed movements are filled with stories of idealistic people who didn't make compromises. A successful movement, though, is filled with people who know that it is wise at times to compromise.
A compromise is what helped the March on Washington take flight, some historians say.
The original March on Washington wasn't supposed to be just about race but about economic issues as well. Organizers originally billed it as a march for "jobs and freedom."
Yet King and others de-emphasized the jobs' focus of the march because they thought it would jeopardize the passage of the pending civil rights bill, says Podair, the Lawrence University professor.
Talking about poverty and inequality at the 1963 march would have alienated potential Northern white supporters who would have seen such rhetoric as a ploy to redistribute money from the white middle class to blacks, Podair says.
Instead, organizers reassured them by focusing on King's dream of racial equality, he says.
"The reason they can get Northern whites to support the march is to say we're not going to touch your wallets," Podair says. "What we're going to do is ask the South to give African-Americans their political rights, something they should have done 100 years ago. But we're not going to redistribute income."
Those commemorating the 50th anniversary of King's speech during various events in Washington this month can learn from the leaders of the 1963 march, Podair says.
If the commemoration speeches are confined to racial issues such as the Trayvon Martin case, they won't be as powerful. But if they also talk about economic inequality, a major issue for white voters, they can also do what King originally did: cast a vision of America that appeals to all types of people.
"Sometimes it makes you feel good to preach to the choir," Podair says, "but after a while you have to go outside the church and find other people for your coalition."
3. Redefine the meaning of punishment
On July 6, 1892, 300 armed detectives confronted a group of unionized steelworkers who had been locked out of a steel mill in Homestead, Pennsylvania. The workers, who were striking for better wages at a time when people routinely worked 12-hour-per-day, six-day weeks, fought back with stones and guns. They eventually forced the armed detectives to surrender. Three workers and seven detectives died.
That confrontation is now known as the Homestead Strike. It pitted ordinary workers against steel titan Andrew Carnegie. Carnegie eventually crushed the workers' union, reduced wages and eliminated 500 jobs.
The past can inspire, yet it can also be intimidating. Some believe that contemporary Americans are too jaded and lazy to take the risks that 19th century workers at the Homestead Mill took. Can anyone envision striking fast-food workers fighting pitched battles against armed troops today?
One historian who has studied movements, though, says the belief that modern Americans lack the right stuff to rise up is "hogwash."
Sam Pizzigati is the author of "The Rich Don't Always Win," a book that traces how ordinary Americans in the first part of the 20th century rose up against plutocrats like Carnegie to create a vibrant middle class. Pizzigati calls that battle a "forgotten triumph."
When people experience enough pain, they will mobilize, says Pizzigati, a labor journalist and associate fellow at the Institute for Policy Studies.
"When people's situation becomes worse, when something changes and things that people took for granted have suddenly gone by the board and they see their position in society sinking, that's a powerful factor that can drive movements," Pizzigati says.
