International Women’s Day originally commemorated the working rights protest led by female garment workers. Many seem to forget the holiday’s ties to the working rights movement in the United States and the Socialist Party.
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.
