How did Jackie Robison advocate for black advancement during the Jim Crow era

In his first year with the movement, Jackie crisscrossed the country and helped to raise $1 million for the NAACP. By the early 1960s, Robinson raised money for SCLC by hosting jazz concerts in his backyard. The funds were raised to help provide bail money for the jailed activists.

Jackie and his family also participated in Civil Rights marches. He was on the front line during the famous “March on Washington” on Aug. 28, 1963, that culminated with King’s unforgettable “I Have a Dream” speech.
