#NiUnaMenos which translates to #NotOneLess symbolizes a highly effective Argentinean campaign against gender-based violence. The movement arose from the fact that In Argentina every 30 hours a woman is murdered simply because she is a woman. Starting with the awareness raising of a few journalists, activists and artists the campaign developed into a collective outcry demanding the end of femicide in Argentina. Thousands of people joined hundreds of organizations throughout the whole country. On June 3rd 2015 #NiUnaMenos reached its peak, when 200,000 people protested on the Plaza del Congreso in Buenos Aires, due to the number of recent and extremely brutal cases of gender-motivated killings.
