25 November 2011 - International Day for the Elimination of Violence against Women

On 17 December 1999 By resolution 54/134 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 sisters, Patria, Minerva and Maria Teresa Mirabal, political activists in the Dominican Republic, on orders of Dominican ruler Rafael Trujillo (1930-1961).
