International Women's Day is celebrates the world over, every year on the eight day of March. It celebrates womanhood and pays tribute to the indomitable spirit of women across the globe.
It's root lies in the early 1900s when oppression and inequality was spurring women to become more vocal and active in campaigning for change. The first National Woman's Day was more or less a political event, observed across the United States on 28 February. It was the initiative of Socialist Party of America.
Women continued to celebrate National Woman's Day on the last Sunday of February until 1913.
