International Women's Day After the Socialist Party of America organised a Women's Day on February 28, 1909 in New York, the 1910 International Socialist Woman's Conference suggested a Women's Day be held annually. After women gained suffrage in Soviet Russia in 1917, March 8 became a national holiday there. The day was then predominantly celebrated by the socialist movement and communist countries until it was adopted in 1975 by the United Nations.
