The idea of an International Women's Day first arose at the turn of the century, which in the industrialized world was a period of expansion and turbulence, booming population growth and radical ideologies.

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.

An international conference, held by socialist organizations from around the world, met in Copenhagen, Denmark, in 1910. The conference of the Socialist International proposed a Women's Day which was designed to be international in character. The proposal initially came from Clara Zetkin, a German socialist, who suggested an International Day to mark the strike of garment workers in the United States. The proposal was greeted with unanimous approval by the conference of over 100 women from 17 countries, including the first three women elected to the parliament of Finland. The Day was established to honour the movement for women's rights, including the right to vote (known as 'suffrage'). At that time no fixed date was selected for the observance.
