The Social-Psychological Origins of the Montgomery Bus Boycott: Social Interaction and Humiliation in the Emergence of Social Movements

This study advances a new explanation of the Montgomery bus boycott, the constitutive event of the U.S. civil rights movement. It introduces new findings to demonstrate that Montgomery, Alabama, was unique in its segregation system, and that unrest among blacks emerged in the narrow time period between late 1953 and 1955. I trace the motivational origins of the boycott in worsening social interactions that caused a sense of abuse and humiliation in black passengers due to three main factors: changing ratios of black and white passengers on the public buses; labor-related issues that frustrated the bus drivers; and the impact of the 1954 Brown decision on the bus drivers. This study calls for a framework that conceptualizes and connects lived experiences and real contentious social interactions with the emergence of protest motivations and social movements. Accordingly, I stress the importance of distinguishing between causes that explain the emergence of movements and factors that explain the momentum and success of movements.
