By resolution 54/134 of 17 December 1999, the United Nations General Assembly designated 25 November as the International Day for the Elimination of Violence against Women, and invited governments, international organizations and NGOs to organize activities designed to raise public awareness of the problem on that day.

Women's activists have marked 25 November as a day against violence since 1981. This date came from the brutal assassination in 1960, of the three Mirabal sisters, political activists in the Dominican Republic, on orders of Dominican ruler Rafael Trujillo (1930-1961).

On 20 December 1993 the General Assembly, by resolution 48/104, adopted the Declaration on the Elimination of Violence against Women.

From 25 November, the International Day for the Elimination of Violence against Women, to 10 December, Human Rights Day, the 16 Days of Activism against Gender-Based Violence Campaign is a time to galvanize action to end violence against women and girls around the world.

This year, the United Nations Secretary-General’s Campaign UNiTE to End Violence against Women invites you to “Orange the world: End violence against women and girls.” Join the UNiTE campaign and organize “Orange Events” between 25 November and 10 December 2015.
