In 1975 the United Nations declared March 8 as International Women's Day. Today it is celebrated in as a national holiday in many countries around the world. In the U.S. International Women’s day inspired the designation of March as Women's History Month.
The idea for a women's day first arose at the turn of the 20th century among members of the Socialist Party of America. This was the only major political party at the time to advocate for women’s right vote. Women of this party helped to organize the first national Women's Day on February 28, 1909. Two years later, in 1911, Women's Day became an international event. Greeted with the unanimous approval of 100 women from 17 countries at the Socialist International meeting in Denmark, the first global celebration occurred on March 19. The date was changed to March 8 on the eve of World War I, when women held rallies to protest the war.
Women's History Month began as a weeklong celebration to coincide with International Women's Day in 1978. The U.S. Congress expanded the week to a full month in 1987.
