From exile in Paraguay, Juan Domingo Peron (1895-1974), former dictator of Argentina, ordered his sympathizers to harass the government through riots, sabotage, and terrorism. On June 14, 1956, Peronist rebels rose in revolt in the provinces of Santa Fe, La Pampa, and Buenos Aires. Declaring martial law, the provisional government, headed by General Pedro Pablo Eugenio Aramburu (1903-70), sent in troops to restore order. Many on both sides were killed and wounded before the revolt was suppressed; more than 2,000 civilians and military men were arrested, 38 of whom were executed. Later in 1956 other Peronist plots were uncovered and squashed. A neo-Peronist Popular Union party urged voters to cast blank ballots in the forthcoming elections for a constituent assembly. Violent clashes between proponents for and against the restoration of a constitutional government became frequent. When the elections were over in 1957, the single largest block of votes was blank, but those who did vote elected pro-reform candidates who held about 60 percent of the assembly seats. The assembly voted to restore the 1853 constitution, but little else was accomplished. The government was hindered by strikes by telephone and telegraph employees and by general strikes by antigovernment workers, most of whom were Peronists. These disputes caused much damage, large production losses, and general political and economic chaos.
