Mirabal Sisters Assassinated in Dominican Republic

Context

Rafael Trujillo seized control of the Dominican Republic in 1930 and maintained power through a network of repression, patronage, and violence that lasted three decades. His rule included the 1937 border massacre of thousands of Haitians and intensified crackdowns after the 1959 Cuban Revolution energized local dissidents. In response, opponents formed groups such as the 14th of June Movement to distribute information about the regime's crimes and organize against it.

The Mirabal family lived in the central Cibao region. Although their parents discouraged political involvement, three of the four daughters—Patria, Minerva, and María Teresa—joined the resistance alongside their husbands. Minerva, the first woman to graduate from law school in the country, drew particular attention after rejecting Trujillo's advances at a social gathering; authorities later revoked her law license as punishment.

By 1960 the regime had arrested numerous dissidents, including the sisters and their husbands, but released the women while keeping some spouses imprisoned. The sisters continued their work under the nickname Las Mariposas, or the Butterflies, despite ongoing surveillance and harassment.

What Happened

On November 25, 1960, Patria, Minerva, and María Teresa Mirabal received permission to travel to the prison in Puerto Plata to visit their husbands. Accompanied by their driver, Rufino de la Cruz, the sisters drove the winding northern roads of the Dominican Republic.

On the return journey, agents of Trujillo's secret police stopped the vehicle. The four occupants were overpowered and killed. The perpetrators then placed the bodies inside the car and pushed it off a cliff in an effort to present the deaths as a roadside accident.

The staging failed to convince anyone. Investigations after the fall of the regime later confirmed that Trujillo had personally ordered the killings.

Aftermath

News of the murders spread quickly and provoked widespread anger across the Dominican Republic. The transparent attempt to disguise state violence only deepened public revulsion toward the regime and its methods. International attention also increased, further isolating Trujillo.

Six months later, on May 30, 1961, Trujillo himself was killed in a roadside ambush carried out by a coalition of military officers and dissidents.

Legacy

The Mirabal sisters became central figures in Dominican memory of the struggle against dictatorship. Their story has been preserved in novels, films, and school curricula, underscoring themes of courage and sacrifice in the face of authoritarian power.

Their deaths also acquired global resonance. In 1999 the United Nations General Assembly designated November 25 as the International Day for the Elimination of Violence Against Women, citing the sisters' case as a catalyst for recognizing the link between political repression and gender-based violence.
