What events that led to the Montgomery bus boycott were set in motion when what?

The Montgomery Bus Boycott was set in motion when Rosa Parks was arrested on December 1, 1955, for refusing to give up her seat to a white passenger on a segregated bus. Her act of civil disobedience sparked outrage and galvanized the African American community in Montgomery, Alabama. This led to the formation of the Montgomery Improvement Association, which organized the boycott of the city’s buses, aiming to protest racial segregation and demand equal treatment. The boycott lasted for over a year, becoming a pivotal moment in the American Civil Rights Movement.
