4. The Mirabal Sisters
These three sisters, Patria, Minerva, and Maria Teresa Mirabal were assassinated by dictator Rafael Trujillo in the Dominican Republic. However, that incident made people understand how cruel and corrupted the dictator was, something that led to his assassination six months later, too. As a result, the 25th of November became the International Day for the Elimination of Violence against Women to pay their dues to the three sisters.
