On November 25, 1960, Trujillo killed three of the four Mirabal sisters, nicknamed "Las Mariposas" (The Butterflies). The victims were Patria Mercedes Mirabal (born on February 27, 1924), Argentina Minerva Mirabal (born on March 12, 1926), and Antonia María Teresa Mirabal (born on October 15, 1935). Along with their husbands, the sisters were conspiring to overthrow Trujillo in a violent revolt. The Mirabals had communist ideological leanings, as did their husbands. The sisters have received many honors posthumously and have many memorials in various cities in the Dominican Republic. Salcedo, their home province, changed its name to Provincia Hermanas Mirabal (Mirabal Sisters Province). The International Day for the Elimination of Violence against Women is observed on the anniversary of their deaths.
