At an International Conference of Working Women in Copenhagen, a woman named Clara Zetkin presents the idea of an International Women's Day. She proposes that every year, in every country around the world, there should be a celebration on the same day–a Women's Day–to press for their demands.
The conference, which is attended by 100 women from 17 countries, representing unions, socialist parties, and working women's clubs, unanimously approves the suggestion, resulting in the first International Women's Day.
