A revealing exploration of domestic fascism in the United States from the 1930s to the January 6th insurrection in Washington, D.C. In 1951, the Civil Rights Congress presented to the United Nations We Charge Genocide, a more than two-hundred-page petition that held the United States accountable for genocide against African Americans. This landmark text represented the dawn of Black Lives Matter and is as relevant today as it was then, as evidenced by the rise of white supremacist groups across the nation, and the January 6th Capitol riot which disclosed the specter of a fascist revival in the U.S. Tracing this specter to its roots, We Charge Genocide! provides an original interpretation of American fascism as a permanent and longstanding current in U.S. politics dating to the origins of U.S. settler-colonialism. Picking up where Angela Davis’s 1971 essay, “Political Prisoners, Prisons, and Black Liberation,” left off, We Charge Genocide! reveals how the United States legal system has contributed to the growth of fascist states and fascist movements domestically and internationally. American Studies scholar Bill V. Mullen contends that the preservation of a white supremacist world order—and the prevention of revolutionary threats to that order—structure the discourse and practice of U.S. fascism. He names this fascist modality the “counterrevolution of law” in tribute to the radicals on the American Left, such as George Jackson, Angela Davis, Herbert Marcuse, and the Black Panther Party, who perceived the American state’s destruction of revolutionary groups and ideas as a distinctive form of American fascism. Mullen argues that U.S. law, particularly U.S. “race law,” has been an enabling mechanism for modalities of fascist rule that have locked historic blocs of non-white populations into an iron cage of legal and extralegal violence. To this end We Charge Genocide! offers a legal historiography of U.S. fascism rooted in law’s capacity to legitimate and sustain racial domination. By recovering the legacy of important organizations, such as the Civil Rights Congress and Black Panther Party, which have both theorized and resisted American legal fascism, Mullen demonstrates how their work and critical theorists like Davis, Marcuse, Jackson, Walter Benjamin and Ernst Fraenkel illuminate the threat of American legal fascism to its most vulnerable racialized victims of state violence in our time, including gender and transgender violence.
