International Women’s Day (then International Working Women’s Day) was introduced during the International Conference of Working Women in Copenhagen, Denmark.
The origins of the holiday can be traced back to March 8, 1857, when garment workers in New York City staged a protest against inhumane working conditions and low wages, according to the United Nations. The police attacked the protesters and dispersed them, but the movement continued and led to the creation of the first women’s labor union.
