The Mirabal sisters, known as the Butterflies, were four Dominican women who opposed the dictatorship of Rafael Trujillo in the Dominican Republic during the 1950s. The sisters—Patria, Minerva, María Teresa, and Dedé—became symbols of resistance against oppression and violence. Their activism was rooted in a desire for freedom and justice in their country. On November 25, 1960, the Mirabal sisters were assassinated by Trujillo's regime, which sought to silence their dissent. Their legacy continues to inspire movements for human rights and gender equality. In 1999, the United Nations designated November 25 as the International Day for the Elimination of Violence Against Women in their honor.
