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.
