Answer:
The outcome of the 1963 March on Washington was that President Johnson signed the Civil Rights Act and Voting Act. It also showed the power of people working together to bring about change.
Step-by-step explanation:
The March on Washington for Jobs and freedom that occurred on August 28th, 1963 was organized by A. Philip Randolph and Bayard Rustin. MLK was an invited speaker and obviously in support of the movement but he was not the one who "led" the organization of the March. There were actually 10 main speakers that day at the rally. The Freedom Riders were civil rights activists engaging in an ongoing protest that started before the March on Washington (in 1961). The Thirteenth Amendment is the amendment that abolished slavery. There were no efforts to overturn it. There were demonstrations throughout the United States after the March that often turned violent but they were not expressly tied to organization by the Southern Christian Leadership Conference, nor were they directly tied to the March as an outcome. They were part of general civil rights activism at the time.
