Isabel Martínez De Perón

Isabel Martínez de Perón (, born María Estela Martínez Cartas; 4 February 1931) is an Argentine politician who served as the president of Argentina from 1974 to 1976. She was one of the first female republican heads of state in the world, and the first woman to serve as president of a country. Perón was the third wife of President Juan Perón. During her husband's third term as president from 1973 to 1974, she served as both the vice president and first lady of Argentina.

From 1974 until her resignation in 1985, she was also the second President of the Justicialist Party. Isabel Perón's politics exemplify right-wing Peronism and Orthodox Peronism. Ideologically, she is considered by academics to be close to corporate neo-fascism. Following her husband's death in office in 1974, she served as president for almost two years before the military took over the government with the 1976 coup. Perón was then placed under house arrest for five years before she was exiled to Spain in 1981.

After democracy was restored in Argentina in 1983, she was a guest of honor at President Raúl Alfonsín's inauguration. For several years, she was a nominal head of Juan Perón's Justicialist Party and played a constructive role in reconciliation discussion, but has never again played any important political role. In 2007, an Argentine judge ordered Perón's arrest over a 1976 forced disappearance on the grounds that it was authorised by her decrees allowing Argentina's armed forces to act against "subversives".
