The Primer Congreso Interamericano de Mujeres (First Inter-American Congress of Women) was a feminist meeting held from 21 to 27 August 1947 in Guatemala City, Guatemala. It was called together by the Women's International League for Peace and Freedom (WILPF) and hosted by the Unión Democrática de Mujeres of Guatemala. This organization had been formed by Angelina Acuña de Castañeda, Berta Corleto, Elisa Hall de Asturias, Gloria Méndez Mina de Padilla, Rosa de Mora, Irene de Peyré, and Graciela Quan immediately following the Guatemalan 1944 coup d'état to push for recognition of women's civil rights.
There were representatives from countries throughout the Americas who accepted the invitation to attend the Conference, but the delegates were not country representatives. Instead, the women represented women's clubs throughout the region. The women participating were from: Argentina, Bolivia, Brazil, Canada, Chili, Colombia, Costa Rica, Cuba, El Salvador, Ecuador, Guatemala, Haiti, Honduras, Mexico, Nicaragua, Panama, Puerto Rico, United States, Uruguay and Venezuela. The women were not politically radical but believed in peace, political equality, and security of human welfare. The first press release issued spoke against the Rio Pact, which was simultaneously being discussed at a conference in Rio de Janeiro and urged arming the nation states of the Western Hemisphere and consolidating their agreement for reciprocal assistance. The women insisted on their right to speak on international issues and urged peace in the region.
The meeting was presided over by the Panamanian delegate, Gumercinda Páez with the Guatemalan First Lady, Elisa Martínez de Arévalo, as honorary president.Heloise Brainerd acted as General Secretary. Funding for the event came mainly from North American sources including the National Council of Negro Women, the National Federation of Business and Professional Women's Clubs, the Pan-American League of Miami, the People’s Mandate Committee, the US WILPF section and Zonta International.
