I Cannot Submit to Injustices

Critical works by legendary Black radical and political prisoner Martin Sostre

I Cannot Submit to Injustices is a collection of works by Black Puerto Rican revolutionary Martin Sostre. As a founding figure of both the prison abolition movement and contemporary Black anarchism, Sostre’s eminence as a political thinker and tireless activist continues to gain wider recognition.

These texts represent decades of Sostre’s work as an agitator, teacher, and intellectual in the face of intense state repression, including years in solitary confinement as punishment for his activism. While in prison, Sostre established radical study groups and lending libraries, published several revolutionary newspapers, organized chapters of the Black Panther Party, and fought for the rights of incarcerated workers. A self-taught lawyer, Sostre’s strategy was to struggle on the offensive, pressing legal battles that established the constitutional rights of prisoners and refusing to submit to body searches by guards he deemed state-sanctioned sexual assault, for which he was beaten nearly a dozen times. With never-before-published interviews and speeches alongside powerful essays reproduced for the first time since their original publication, this volume offers readers overdue access to Sostre’s ideas about anarchism, armed struggle, and Black liberation in his own words.

A foreword by Lorenzo Kom’boa Ervin (Anarchism and the Black Revolution), who was introduced to anarchism by Sostre while they were imprisoned together, in conversation with William C. Anderson (Nation on No Map), reflects on Martin Sostre’s teachings on Black revolutionary organizing and on his enduring legacy in the Black radical tradition.

“If Attica fell to us in a matter of hours despite it being your most secure maximum security prison-fortress equipped with your latest repressive technology, so shall fall all your fortresses, inside and out. Revolutionary spirit conquers all obstacles.” —Martin Sostre, “The New Prisoner” (1973)
