On the first of December Rosa Parks travelled home in the front seat of the bus after a long day of work. She was sitting in the white section of the bus and when she was told to move she remained in her seat. Rosa parks was arrested and fined $10. She was later bailed out of jail by E.D. Nixon a well known black leader whom believed would be a great plaintiff in a legal challenge of the segregation. News of a boycott spread fast around Montgomery many African American leaders started to give their support, (including Martin Luther King Jr.).
40,000 or more African American bus riders boycotted the system the next day. On December 5 Montgomery Improvement Association (MIA) was formed with King being the head of the organisation. The demands of the organisation were the hiring of black drivers, and a first-come, first seated policy. A group of five Montgomery women, represented by NAACP sued the city. These five women were seeking to have the segregation laws in buses totally removed.
On June the Fifth 1956 Montgomery federal court ruled that any law requiring racially segregated seating on buses violated the 14th Amendment to the U.S. Constitution
