Abstract: This study examines Jim Crow practices and the Black Freedom Struggle in Kansas between 1945 and 1960, focusing at the state level. It proceeds in three sections. First, it examines Jim Crow in housing, employment, schools, public accommodations, and sundown towns. Second, it addresses the enforcement of these practices through mob violence and, to a greater degree, police violence. Third, it investigates the activism of Black Kansans who were, irrespective of age, gender, or class, determined to destroy Jim Crow through public protests, legal strategies, and physical self-defense, even if they represented considerable ideological, methodological, and strategic diversity. The study is based primarily on extensive research in regional and local newspapers, in public and university archives, and in oral histories with contemporary Black activists. Because of the limited time period involved, it utilizes a topical approach overall but, within this framework, addresses change over time. Before proceeding, the study briefly examines the long history of racism against Blacks and Black resistance to it in Kansas before 1945.
