Rosa Parks was not just some black lady who would not give up her seat on a bus.The whole thing was planed. At the time, Parks was secretary of the Montgomery chapter of the NAACP. She had recently attended the Highlander Folk School, a Tennessee center for training activists for workers' rights and racial equality. She acted as a private citizen "tired of giving in" Black activists had begun to build a case to challenge state bus segregation laws around the arrest of a 15-year-old girl, Claudette Colvin, a student at Booker T. Washington High School in Montgomery. On March 2, 1955, Colvin was handcuffed, arrested and forcibly removed from a public bus when she refused to give up her seat to a white man. At the time, Colvin was an active member in the NAACP Youth Council; Rosa Parks was an advisor. f E. D. Nixon, president of the local NAACP chapter and a member of the Brotherhood of Sleeping Car Porters. Nixon intended that her arrest be a test case to allow Montgomery's black citizens to challenge segregation on the city's public buses. With this goal, community leaders had been waiting for the right person to be arrested, a person who would anger the black community into action, who would agree to test the segregation laws in court, and who, most importantly, was "above reproach". When Colvin was arrested in March 1955, Nixon thought he had found the perfect person, but the teenager turned out to be pregnant. Nixon later explained, "I had to be sure that I had somebody I could win with." Parks was a good candidate because of her employment and marital status, along with her good standing in the community.
