Six days later, between 250,000 and 350,000 people gathered in front of the Casa Rosada, Argentina's government house, to demand Juan Perón's release. At 11 pm, Juan Perón stepped onto the balcony of the Casa Rosada and addressed the crowd. Biographer Robert D. Crassweller claims that this moment was particularly powerful because it dramatically recalled important aspects of Argentine history. Crassweller writes that Juan Perón enacted the role of a "caudillo" addressing his people in the tradition of Argentine leaders Rosas and Yrigoyen. Crassweller also claims that the evening contained "mystic overtones" of a "quasi-religious" nature.
