50 Years Later: What Would You March For? #IMarchFor If the March on Washington were today, what cause would you march for? More than 1,000 buses, 37 trains, and 14 planes brought civil rights marchers from across the country to the March on Washington for Jobs and Freedom. National Archives On Aug. 28, 1963, nearly 250,000 Americans descended on the nation's capital for the March on Washington for Jobs and Freedom. Organizers expected 100,000 marchers to attend, and more than double that number showed up, sending a message to Congress and the world that their grievances needed to be addressed. As we commemorate the 50th anniversary of this march where Martin Luther King Jr. delivered his "I Have a Dream" speech, we're reminded once again of the power of a peaceful protest, and the ability of Americans to come together to enact change. And so, we want to know: What are the causes that you care most about today? What issue would get you marching?
