The August 28 march will also commemorate Detroit’s 1963 Walk to Freedom led by Rev. Martin Luther King, Jr. At the Walk to Freedom, King delivered his “I Have a Dream” speech for the first time before sharing it with the world later that summer at the March on Washington.
From Michigan History Magazine:
In the spring of 1963, Detroiters looked for a way to commemorate the anniversary of racial violence that tore through their city twenty years earlier that left 34 people dead and hundreds injured. The Detroit Council for Human Rights called for a "Walk to Freedom," because many of "the same basic, underlying causes" of the 1943 disturbance were "still present."
On June 23, 1963, an estimated 125,000 people marched down Detroit's Woodward Avenue carrying placards and singing "We Shall Overcome." National and state leaders who marched along with Reverend King included United Auto Workers president Walter Reuther, former Michigan governor John B. Swainson, and Detroit mayor Jerome Cavanagh.
The march ended at Cobo Hall where the Reverend King was cheered by thousands of marchers when he emphasized that segregation needed to end…(and) spoke of having a "dream" where whites and blacks were "walking together, hand in hand," in harmony and equality.
Later that year, King was named the TIME magazine man of the year. The following year, he won the Nobel Peace Prize.
