Examining American history through the lens of black girlhood underscores just how thoroughly childhood everywhere is not “natural” but depends heavily on its social construction. Furthermore, ideas about childhood innocence are deeply racialized and gendered. At the end of Reconstruction, African Americans lost many of the social and political gains achieved after the Civil War. This signaled the emergence of Jim Crow, placing many blacks in the same social, political, and economic position that they occupied before freedom. Black girls who came of age in the 20th century lived through Jim Crow, the civil rights movement, Black Power, and the rise of the New Right. Moreover, black girls in the 20th century inherited many of the same burdens that their female ancestors carried—especially labor exploitation, criminalization, and racist notions of black sexuality—which left them vulnerable to physical, emotional, and sexual violence. In short, black girls were denied the childhood protections that their white counterparts possessed. If fights for cultural representation, economic justice, equal access to education, and a more just legal system are familiar sites of black struggle, then examining black girlhood reveals much about the black freedom movement. Activists, parents, and community advocates centered black girls’ struggles within their activism. Black girls were also leaders within their own right, lending their voices, bodies, and intellect to the movement. Their self-advocacy illustrates their resistance to systemic oppression. However, resistance in the more obvious sense—letter writing, marching, and political organizing—are not the only spaces to locate black girls’ resistance. In a nation that did not consider black children as children, their pursuit of joy and pleasure can also be read as radical acts. The history of 20th-century black girlhood is simultaneously a history of exclusion, trauma, resilience, and joy.
