This book examines key moments in which collective and state violence invigorated racialised social boundaries around Mexican and African Americans in the United States, and in which they violently contested them.

Bringing anti-Mexican violence into a common analytical framework with anti-black violence, A savage song examines several focal points in this oft-ignored history, including the 1915 rebellion of ethnic Mexicans in South Texas, and its brutal repression by the Texas Rangers and the 1917 mutiny of black soldiers of the 24th Infantry Regiment in Houston, Texas, in response to police brutality.

Aragon considers both the continuities and stark contrasts across these different moments: how were racialised constructions of masculinity differently employed? How did African and Mexican American men, including those in uniform, respond to the violence of racism? And how was their resistance, including their claims to manhood and nation, understood by law enforcement, politicians, and the press?

Building on extensive archival research, the book examines how African and Mexican American men have been constructed as 'racial problems', investigating, in particular, their relationship with law enforcement and ideas about black and Mexican criminality.
