<p>Rosa Lee Parks, whose refusal to give up her bus seat to a white man in Motgomery, Ala., sparked the modern civil rights movement, died Monday. She was 92.</p><p>Mrs. Parks died at her home of natural causes, said Karen Morgan, a spokeswoman for U.S. Rep. John Conyers, D-Mich.</p><p>Mrs. Parks was 42 when she committed an act of defiance in 1955 that was to change the course of American history and earn her the title "mother of the civil rights movement."</p><p>At that time, Jim Crow laws in place since the post-Civil War Reconstruction required separation of the races in buses, restaurants and public accommodations throughout the South, while legally sanctioned racial discrimination kept blacks out of many jobs and neighborhoods in the North.</p><p>The Montgomery seamstress, an active member of the local chapter of the National Association for the Advancement of Colored People, was riding on a city bus Dec. 1, 1955, when a white man demanded her seat.</p><p>Mrs. Parks refused, despite rules requiring blacks to yield their seats to whites. Two black Montgomery women had been arrested earlier that year on the same charge, but Mrs. Parks was jailed. She also was fined $14.</p><p>Speaking in 1992, she said history too often maintains "that my feet were hurting and I didn't know why I refused to stand up when they told me. But the real reason of my not standing up was I felt that I had a right to be treated as any other passenger. We had endured that kind of treatment for too long."</p><p>Her arrest triggered a 381-day boycott of the bus system organized by a then little-known Baptist minister, the Rev. Martin Luther King Jr., who later earned the Nobel Peace Prize for his work.</p><p>"At the time I was arrested I had no idea it would turn into this," Mrs. Parks said 30 years later. "It was just a day like any other day. The only thing that made it significant was that the masses of the people joined in."</p><p>The Montgomery bus boycott, which came one year after the U.S. Supreme Court's landmark declaration that separate schools for blacks and whites were "inherently unequal," marked the start of the modern civil rights movement.</p><p>The movement culminated in the 1964 federal Civil Rights Act, which banned racial discrimination in public accommodations.</p><p>After taking her public stand for civil rights, Mrs. Parks had trouble finding work in Alabama. Amid threats and harassment, she and her husband Raymond moved to Detroit in 1957. She worked as an aide in Conyers' Detroit office from 1965 until retiring Sept. 30, 1988. Raymond Parks died in 1977.</p><p>Mrs. Parks became a revered figure in Detroit, where a street and middle school were named for her and a papier-mache likeness of her was featured in the city's Thanksgiving Day Parade.</p><p>Mrs. Parks said upon retiring from her job with Conyers that she wanted to devote more time to the Rosa and Raymond Parks Institute for Self Development. The institute, incorporated in 1987, is devoted to developing leadership among Detroit's young people and initiating them into the struggle for civil rights.</p>
