The Montgomery Bus Boycott, initiated in 1955, was a pivotal event in the American Civil Rights Movement. Sparked by Rosa Parks' arrest for refusing to give up her bus seat to a white passenger, this nearly year-long boycott sought to challenge racial segregation on public buses in Montgomery, Alabama. Led by figures such as Martin Luther King Jr., the boycott united the African American community and garnered national attention, highlighting the injustices of segregation. The successful outcome, resulting in a Supreme Court ruling against bus segregation, demonstrated the power of nonviolent protest and laid the groundwork for further civil rights activism across the United States.
