November 25th is designated by the United Nations as “International Day for the Elimination of Violence Against Women.”  The date was selected to “commemorate the lives of the Mirabal sisters,” who were assassinated on November 25, 1960 during the Trujillo dictatorship, as explained in the General Assembly resolution designating the day:

Previously, 25 November was observed in Latin America and a growing number of other countries around the world as “International Day Against Violence Against Women”. With no standard title, it was also referred to as “No Violence Against Women Day” and the “Day to End Violence Against Women”. It was first declared by the first Feminist Encuentro for Latin America and the Caribbean held in Bogota, Colombia (18 to 21 July 1981). At that Encuentro women systematically denounced gender violence from domestic battery, to rape and sexual harassment, to state violence including torture and abuses of women political prisoners. The date was chosen to commemorate the lives of the Mirabal sisters. It originally marked the day that the three Mirabal sisters from the Dominican Republic were violently assassinated in 1960 during the Trujillo dictatorship (Rafael Trujillo 1930-1961). The day was used to pay tribute to the Mirabal sisters, as well as global recognition of gender violence.

The resolution “[i]nvites, as appropriate, Governments, the relevant agencies, bodies, funds and programmes of the United Nations system, and other international organizations and non-governmental organizations, to organize on that day activities designed to raise public awareness of the problem of violence against women.”
