He ultimately attended the American Baptist Theological Seminary and Fisk University in Nashville, Tennessee.
He began organizing sit-in demonstrations at whites-only lunch counters and volunteering as a Freedom Rider, enduring beatings and arrests while traveling around the South to challenge segregation.
Lewis helped found the Student Nonviolent Coordinating Committee and was named its chairman in 1963, making him one of the Big Six at a tender age.
The others, in addition to King, were Whitney Young of the National Urban League; A. Philip Randolph of the Negro American Labor Council; James L. Farmer Jr., of the Congress of Racial Equality; and Roy Wilkins of the NAACP.
All six met at the Roosevelt Hotel in New York to plan and announce the March on Washington.
The huge demonstration galvanized the movement, but success didn’t come quickly.
After extensive training in nonviolent protest, Lewis and the Rev. Hosea Williams led demonstrators on a planned march of more than 50 miles (80 kilometers) from Selma to Montgomery, Alabama’s capital, on March 7, 1965.
A phalanx of police blocked their exit from the Selma bridge.
Authorities shoved, then swung their truncheons, fired tear gas and charged on horseback, sending many to the hospital and horrifying much of the nation. King returned with thousands, completing the march to Montgomery before the end of the month.
Lewis turned to politics in 1981, when he was elected to the Atlanta City Council.
