Final answer:
Jo Ann Robinson was a key figure in the Montgomery Bus Boycott, contributing to its organization by producing and distributing leaflets to mobilize the African American community.
Step-by-step explanation:
Jo Ann Robinson played a crucial role in the Montgomery Bus Boycott of 1955-1956, a pivotal event in the Civil Rights Movement. As a member of the Women's Political Council, Robinson was instrumental in organizing the initial boycott after Rosa Parks' arrest. She worked tirelessly to produce and distribute tens of thousands of leaflets that informed the African American community in Montgomery of the boycott and its logistics.
Robinson, along with other civil rights leaders such as E. D. Nixon, Martin Luther King Jr., and Rosa Parks, was committed to maintaining the boycott beyond the first day. African American citizens of Montgomery, in a display of solidarity and nonviolent resistance, decided to forgo using the segregated bus system and walked or car-pooled for 381 days. This collective effort eventually led to a Supreme Court ruling that ended segregation on Montgomery buses.
