The National Day of Women's Political Rights is observed in Argentina every September 23. This day commemorates the law passed on September 23, 1947, which granted women the right to vote and established political equality between men and women. The celebration is closely associated with Eva Perón, known as Evita, who was the First Lady of Argentina from 1946 until her death in 1952. Eva Perón played a significant role in advocating for women's suffrage and was instrumental in the law's adoption by the Argentine Congress. Additionally, she founded the Female Peronist Party in 1949, which became the largest female political party in Argentina, focusing on political and feminist goals. The National Day of Women's Political Rights was officially established in 1997 to honor this landmark achievement in Argentine history.
