John Lewis (Stephan James)
As the chairman of the Student Nonviolent Coordinating Committee (SNCC) at 25, John Lewis was known at the time of the Selma marches as the youngest "Big Six" civil rights leader. He continued with his civil rights work through the '60s, and moved into politics in the '70s. In 1987 he was elected congress, representing Georgia's 5th District (the same seat previously occupied by Andrew Young). And he's been there ever since.
