America, National Women's Day was first observed in the United States on February 28. Women continued to celebrate on the last sunday of that month until 1913.1910Clara Zetkin: A German socialist who proposed the creation of International Women's Day. The organisation "Second International", the original "Social Internatonal", came together in Copenhagen, where they established Women's Day in an internacional character, to honor women's rights movement and to assist in achieving the rights to vote for women worldwide. The proposal was greeted with unanimous approval by the conference of over 100 women from 17 countries, which included the first three women elected to the Finnish parliament. No fixed date was selected for the observance.1911As a result of the decision taken in Copenhagen the previous year, International Women's Day was marked for the first time (19 March) in Austria, Denmark, Germany and Switzerland, where more than one million women and men attended demonstrations. Besides the right to vote and hold public office, they demanded the right to work, to professional education and an end to discrimination in the workplace.Less than a week later, on 25 March, the tragic factory fire of "Triangle Shirtwaist" in New York, took the lives of more than 140 girls who worked in the factory, mostly Italian and Jewish immigrants. This event had a significant impact on labor legislation in the United States, and the working conditions leading up to the disaster were invoked during subsequent observances of International Women's Day.1913-1914As part of the peace movement on the eve of World War I, Russian women observed the International Women's Day on the last Sunday in February 1913. Elsewhere in Europe, as the German poster here on the right depicts, on 8 March of the following year, women formed rallies to protest against the war or to express solidarity with their sisters.1917With 2 million Russian soldiers dead in the war, Russian women again chose the last Sunday in February to strike for "bread and peace". Political leaders opposed the timing of the strike, but the women went anyway. The rest is history: Four days later the Czar was forced to abdicate and the provisional government gave women the right to vote.That historic Sunday fell on 23 February on the Julian calendar then in use in Russia, but on 8 March on the Gregorian calendar in use elsewhere. Above the massive demonstration on that day in Petrograd.In the West, International Women's Day was commemorated during the 1910s and 1920s. Later, the date was forgotten and was only recovered by the feminist movement, already during the 1960s, and ultimately adopted by the United Nations in 1977.In Brazil, we can say that the day 24 February 1932 was a milestone in the history of Brazilian women. On this date women's suffrage was established. Women conquered, after many years of discussions and claims, the right to vote and be elected to positions in the executive and legislative branches.Since the first years, International Women's Day has assumed a new global dimension for women in developed and developing countries. Unfortunately, today, the celebration of International Women's Day
