Mar�a Estela Mart�nez Cartas de Per�n, better known as Isabel Mart�nez de Per�n or Isabel Per�n, is a former President of Argentina. She was the third wife of the former President, Juan Per�n. 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. This made her the first female president of any country in the world. In 2007, an Argentine judge ordered the arrest of Isabel Per�n over the forced disappearance of an activist in February 1976, on the grounds that the disappearance was authorized by her signing of decrees allowing Argentina's armed forces to take action against "subversives". She was arrested near her home in Spain on 12 January 2007. Spanish courts subsequently refused her extradition to Argentina.
