How three sisters became the butterflies that brought down a Caribbean dictator

History · Published 3 October 2026 Swipe more like this →

In short: Patria, Minerva, and María Teresa Mirabal were once ordinary members of the Dominican elite. After rejecting the advances of dictator Rafael Trujillo, they transformed into "Las Mariposas," the clandestine resistance leaders whose brutal assassination in 1960 ignited the final collapse of a thirty-one-year regime of terror.

The Mirabal sisters grew up in a prosperous landowning family in Ojo de Agua. Their path to revolution began in 1949, when Minerva caught the attention of Rafael Trujillo, a dictator who had seized power in 1930. When Minerva repeatedly rejected his persistent sexual advances, the regime retaliated by harassing the family, imprisoning their father, and stripping the sisters of their professional opportunities. These personal affronts, combined with the regime's broader history of human rights abuses—such as the 1937 Parsley Massacre—radicalized the sisters.

Minerva, who became one of the first women in the country to graduate from law school, channeled her defiance into organized resistance. Alongside her sisters Patria and María Teresa, she helped form the Fourteenth of June Movement, a national effort named in memory of a failed 1959 coup. Operating under the code name "Las Mariposas," or "The Butterflies," the women distributed anti-regime literature, gathered weapons, and established secret cells. Despite repeated arrests, torture, and imprisonment, they remained steadfast in their opposition to Trujillo’s absolute control.

On November 25, 1960, Trujillo’s henchmen intercepted the sisters and murdered them in a staged car crash, a tactic the regime frequently used to eliminate political rivals. Rather than silencing the opposition, the brutality of their deaths galvanized national and international outrage, drawing critical attention to the regime's crumbling stability. The Catholic Church, which had long supported Trujillo, publicly condemned him that same year. The sisters' sacrifice is now commemorated globally every November 25, a date designated by the United Nations to focus on ending violence against women.
