Celebrated annually on March 8, International Women’s Day is traced back to the US in 1907, when more than 15,000 female textile workers marched through New York City, demanding better working conditions and voting rights. In 1909, the Socialist Party of America declared a National Women’s Day, celebrated until 1913 on the last Sunday of February.
In 1910, about 100 women from 17 countries attended the Second International Conference of Women in Copenhagen, Denmark, at which Clara Zetkin proposed the establishment of International Women’s Day, on which women would highlight women’s issues. The following year, more than one million women and men attended International Women’s Day rallies worldwide. In Russia in 1917, women marked the day with a four-day strike for “peace and bread” that was a key event in the lead up to Russia’s October Revolution that year.
