The Raised Fist symbol was popularized in 1948 by Taller de Gráfica Popular, a print shop in Mexico that used art to advance revolutionary social causes.

Its use spread through the United States in the 1960s after artist and activist Frank Cieciorka produced a simplified version for the Student Nonviolent Coordinating Committee: this version was subsequently used by Students for a Democratic Society and the Black Power movement.
