After passing several years between 1940 and 1945 without a women's rights organization, the "Unión Democrática de Mujeres" (UDM) (Women's Democratic Union) was founded on December 19, 1946. It grew out of the "Agrupación de Mujeres Febrerista Residentes en Montevideo" (AMFRM) (Association of Febrerista Women Living in Montevideo), which was connected to the "Concentración Revolucionaria Febrerista", a Febrerista exile group based out of Montevideo, Uruguay. The founders of this group included Carmen Soler, Esther Ballestrino, Lilia Freis, and several others. This group was pressured to disband following the Paraguayan Civil War in 1947.
