This article examines one of the most violent episodes in Mexico’s recent history—the Corpus Thursday massacre orchestrated by the Mexican government against young students on June 10, 1971. The event marked the beginning of a period known as the guerra sucia (dirty war), marked by the systematic repression of students and dissenting political groups by government forces. The present work advocates for “making history with photographs,” urging readers to explore the historical moment through the narratives presented by three distinct historical actors: the press, independent photographers, and the perspective of power from governmental organizations.
