Rosa Parks' commitment to civil rights was shaped by several key experiences, including her upbringing in the segregated South and her involvement with the NAACP. Growing up, Parks witnessed pervasive racism and inequality, which instilled a deep sense of justice. Her work as a secretary for the NAACP exposed her to civil rights activism, empowering her to challenge discrimination. The pivotal moment in her refusal to give up her bus seat in Montgomery was influenced by her lifelong struggles against injustice, becoming a symbol of the civil rights movement.
