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.
Justicialist Party
The Justicialist Party was founded in 1947 by Juan and Evita Perón, and superseded the Labour Party on which Perón had been elected a year earlier. Following the enactment of women's right to vote in 1948, a Peronist Women's Party, led by the First Lady, was also established. All Peronist entities were banned from elections after 1955, when the "Revolución Libertadora" overthrew Perón, and civilian governments' attempt to lift Peronism's ban from legislative and local elections in 1962 and 1965 resulted in military coups.
Basing itself on the policies espoused by Juan Perón as president of Argentina, the party's platform has from its inception centered around populism, and its most consistent base of support has historically been the CGT, Argentina's largest trade union. Perón ordered the mass nationalization of public services, strategic industries, and the critical farm export sector, while enacting progressive labor laws and social reforms, and accelerating public works investment.
