This book follows California’s history of segregation from statehood to the beginning of the long civil rights movement, arguing that the state innovated methods to control and contain African Americans and other people of color. While celebrated in popular discourse for its forward-thinking culture, politics, and science, California also pioneered new ways to keep citizenship white. Schools, streetcars, restaurants, theaters, parks, beaches, and pools were places of contestation where the presence of black bodies elicited forceful responses from segregationists. Black Californians employed innovative measures to dismantle segregation in the nineteenth and twentieth centuries; they borrowed some tactics from race rebels in the South, others they improvised. West of Jim Crow uses California to highlight the significance of African American resistance to racial restrictions in places often deemed marginal to mainstream civil rights histories. Examining segregation in the state sheds light on the primacy of gender and sexuality in the minds of segregationists and the significance of black women, black bodies, and racial science, in the years preceding the modern civil rights struggle. California has much to teach us about the lives of African Americans who crossed the color line and the variety of tactics and strategies employed by freedom fighters across the United States.
