International Women's Day (IWD), originally called International Working Women's Day On 8 March 1857, women working in clothing and textile factories (called 'garment workers') in New York City, in the United States, staged a protest. They were fighting against inhumane working conditions and low wages. The police attacked the protestors and dispersed them. Two years later, again in March, these women formed their first labour union to try and protect themselves and gain some basic rights in the workplace.
On 8 March 1908, 15,000 women marched through New York City demanding shorter work hours, better pay, voting rights and an end to child labour. They adopted the slogan "Bread and Roses", with bread symbolizing economic security and roses a better quality of life. In May, the Socialist Party of America designated the last Sunday in February for the observance of National Women's Day.
Following the declaration of the Socialist Party of America, the first ever National Woman's Day was celebrated in the United States on 28 February 1909. Women continued to celebrate it on the last Sunday of that month through 1913.
