Isabel Martínez de Perón
María Estela Martínez Cartas de Perón (born 4 February 1931), better known as Isabel Martínez de Perón () or Isabel Perón, served as the 42nd President of Argentina from 1974 to 1976. She was the third wife of President Juan Perón. During her husband's third term as president from 1973 to 1974, Isabel served as both vice president and First Lady. Following her husband's death in office in 1974, Isabel served as president of Argentina from 1 July 1974 to 24 March 1976, when the military took over the government and placed her under house arrest for five years, before exiling her to Spain in 1981. She holds the distinction of having been the first woman to have had the title of "President", as opposed to a queen or prime minister.
Elvia Carrillo Puerto
Carillo is noted as having devoted herself full-time to touring Southeastern Mexico with the goal of organizing Mayan women into leagues and preparing them for civic responsibility. The leagues would identify women of special aptitude and train them to fill elective posts in the city and state government. Carillo, after her brother and governor Felipe permitted women the right to vote and hold office, was elected in 1923 to the Yucatán legislature, Mexico's first female member of state legislature. Carillo won the election by an overwhelming 5,115 votes. While a member of government, Carillo promoted the issue of land reform, proposing plans that would provide "campesinos" with farms capable of sustaining their families. In doing so Carillo organized local chapters of women into Gualbertista Central Agrarian Communities for Females, named after her brother Gualberto, a senator and land reform activist.
