The iconic American figure known for her strong support for human rights and social justice is Rosa Parks. She became a pivotal figure in the American civil rights movement, best known for her courageous act of refusing to give up her bus seat to a white passenger in Montgomery, Alabama, in 1955. This act of defiance sparked the Montgomery Bus Boycott, a crucial event in the fight against racial segregation. Parks' commitment to equality and justice has made her a symbol of resistance and a source of inspiration for generations of activists advocating for civil rights.
