The introduction begins with the story of Domitila, a young campesina who escaped to the mountains at night to train for the coming insurrection. Guarding her secret, she endured beatings from her father, who accused her of promiscuity. After her father discovered the revolver hidden underneath her pillow, he affords her a form of respect that he had previously reserved for men. Through Domitila’s personal story, I explain the conditions that drove rural workers to organize, the dramatic rise of state repression against unarmed movements, the left’s radicalization, the subsequent formation of the insurgency, the outbreak of the civil war (1980–1992), women’s organizing in the guerrilla territories and in multiple countries abroad, and the postwar battles to remember an insurgent past. I also contextualize El Salvador within a regional and global Cold War history. After the major actors and temporal scope are identified, I explain how dominant narratives, many rooted in Cold War paradigms, have contributed to the erasure of revolutionary women within feminist histories. I offer an alternative framework and methodology – rooted in dialectical approaches, oral history, and movement archives – that takes seriously the political contributions of revolutionary women.
