Rosa Parks was born in 1913 in Alabama and grew up experiencing racial segregation and discrimination. In 1955, she refused to give up her seat to a white passenger on a bus, which sparked the Montgomery Bus Boycott. The 381-day boycott challenged the legality of racial segregation laws and brought national attention to Martin Luther King Jr. and the emerging civil rights movement. The Supreme Court eventually ruled that segregation on buses was unconstitutional, marking a major victory for civil rights. Rosa Parks went on to write several books and receive the Presidential Medal of Freedom, cementing her legacy as a pioneer of the civil rights movement.
