Rosa Louise Parks was nationally recognized as the “mother of the modern day civil rights movement” in America. Her refusal to surrender her seat to a white male passenger on a Montgomery, Alabama bus, December 1, 1955, triggered a wave of protest December 5, 1955 that reverberated throughout the United States. Her quiet courageous act changed America, its view of black people and redirected the course of history.
Mrs. Parks was born Rosa Louise McCauley, February 4, 1913 in Tuskegee, Alabama. She was the first child of James and Leona Edwards McCauley. Her brother, Sylvester McCauley, now deceased, was born August 20, 1915. Later, the family moved to Pine Level, Alabama where Rosa was reared and educated in the rural school. When she completed her education in Pine Level at age eleven, her mother, Leona, enrolled her in Montgomery Industrial School for Girls (Miss White's School for Girls), a private institution. After finishing Miss White's School, she went on to Alabama State Teacher's College High School. She, however, was unable to graduate with her class, because of the illness of her grandmother Rose Edwards and later her death.
As Rosa Parks prepared to return to Alabama State Teacher's College, her mother also became ill, therefore, she continued to take care of their home and care for her mother while her brother, Sylvester, worked outside of the home. She received her high school diploma in 1934, after her marriage to Raymond Parks, December 18, 1932. Raymond, now deceased was born in Wedowee, Alabama, Randolph County, February 12, 1903, received little formal education due to racial segregation. He was a self-educated person with the assistance of his mother, Geri Parks. His immaculate dress and his thorough knowledge of domestic affairs and current events made most think he was college educated. He supported and encouraged Rosa's desire to complete her formal education.
