Since 1999 the United Nations has recognized November 25 as International Day for Elimination of Violence Against Women. Universally, one in three women will experience sexual and physical violence in their lifetime. The Human Rights Education Associates elaborate on the history of this day:
"The origins of November 25th go back to 1960, when the three Mirabal sisters from the Dominican Republic were violently assassinated for their political activism. The sisters, known as the "Unforgettable Butterflies," became a symbol of the crisis of violence against women in Latin America. November 25th was the date chosen to commemorate their lives and promote global recognition of gender violence, and has been observed in Latin America since the 1980s."
