1960 – The Mirabal sisters of the Dominican Republic are assassinated.
The Mirabal sisters were four Dominican sisters known commonly as Patria, Minerva, María Teresa, and Dedé, who opposed the dictatorship of Rafael Trujillo (El Jefe) and were involved in clandestine activities against his regime. Three of the four sisters (Patria, Minerva, María Teresa) were assassinated on November 25,1960. The last sister, Dedé, died of natural causes on February 1, 2014. The assassinations turned the Mirabal sisters into “symbols of both popular and feminist resistance”. In 1999, in the sisters’ honour, the United Nations General Assembly designated November 25 the International Day for the Elimination of Violence against Women.
