The Revolución Libertadora (Spanish pronunciation: , Liberating Revolution) was a military and civilian uprising that ended the second presidential term of Juan Perón in Argentina, on September 16, 1955.


President Perón was first elected in 1946. In 1949, a constitutional amendment sponsored by the government introduced a number of workers' rights and the possibility of presidential reelection. Perón was reelected in 1952. At the time, his administration was widely supported by the labor unions, the military and the Catholic Church.

However, economic problems, some of the government's policies and Perón's own Christian democracy in Argentina.

By 1955, Perón had lost the support of a large part of the military, who conspired with other political actors (members of the Radical Party and the Socialist Party, as well as conservative groups). There was turmoil in different parts of the country. On June 14, Catholic bishops spoke against Perón during a Corpus Christi procession which turned into an anti-government demonstration.

For several days, there was some fighting in places like the city of Córdoba (Gen. Lonardi's central command), Puerto Belgrano Naval Base near Bahía Blanca, another naval base in Río Santiago, and a mechanized infantry regiment in Curuzú Cuatiá, Corrientes Province.

The rebellion in Corrientes, which was initially defeated, was led by Pedro Eugenio Aramburu, who later became one of the main players of the future government. Two rebel destroyers, that were enforcing the blockade of the Río de la Plata, were strafed by loyalist aircraft. The city of Mar del Plata was subjected to naval bombardment on September 19 by the light cruiser 9 de Julio and several destroyers, and scattered skirmishes and air strikes took place elsewhere, including Buenos Aires itself.

After realizing that the country was on the brink of civil war, Perón resigned and sought asylum in Paraguay, after taking shelter aboard the Paraguayan gunboat Paraguay.

On September 23, General Lonardi assumed the presidency and gave a speech from the balcony of the Casa Rosada, saying that there would be
