The 1976 Argentine coup d'état that overthrew Isabel Perón as President of Argentina on 24 March 1976, while having some right-wing elements, such as its emphasis on order and security, was not a traditional right-wing coup and did not adhere to a specific ideology. A military junta was installed to replace her; this was headed by Lieutenant General Jorge Rafael Videla, Admiral Emilio Eduardo Massera and Brigadier-General Orlando Ramón Agosti. The political process initiated on 24 March 1976 took the official name of "National Reorganization Process", and the junta, although not with its original members, remained in power until the return to the democratic process on 10 December 1983. The coup was planned and executed within the framework of the Condor Plan, a clandestine system of repressive coordination between Latin American countries promoted by the United States, as part of the national security doctrine, which generalized dictatorships in Latin America in order to maintain the control over those countries during the Cold War.
The military coup had been planned since October 1975; the Perón government learned of the preparations two months before its execution. Henry Kissinger met several times with Argentine Armed Forces leaders after the coup, urging them to destroy their opponents quickly before outcry over human rights abuses grew in the United States.
Given the systematic persecution of a social minority, the period has been classified as a genocidal process. This has been established in the sentences of the trials of the perpetrators for crimes against humanity.
Prelude to the coup
When president Juan Perón died of natural causes on 1 July 1974, he was succeeded by his wife (then vice-president) Isabel Perón, also known as "Isabelita." Despite her claim as the country's rightful ruler, she rapidly lost political gravitas and power. A group of military officials, tasked by Perón to aide the vice-president, took control in an effort to revitalize Argentina's deteriorating political and social climate. This shift in governance paved the way for the ensuing coup.
On 5 February 1975 Operativo Independencia was launched. This Vietnam-style intervention aimed to eliminate the guerrillas in the Tucumán jungle, who had maintained strongholds in the area as early as May 1974. In October the country was divided into five military zones, with each commander given full autonomy to unleash a carefully planned wave of repression.
On 18 December, a number of warplanes took off from Morón Air Base and strafed the Casa Rosada in an attempt to overthrow Isabel Perón. The rebellion was brought to a halt four days later through arbitration by a chaplain.
However, the military did succeed in removing the only officer remaining loyal to the government, Air Force commander Héctor Fautario. Fautario drew harsh criticism from the Army and Navy owing to his vehement opposition to their repressive plans, and for his refusal to mobilize the Air Force against the guerrillas' strongholds in the north. Fautario was Videla's final obstacle in his pursuit of power.
By January 1976 the guerrilla presence in Tucumán had been reduced to a few platoons. Meanwhile, the military, fully backed by the local élite, along with Chilean strongman Augusto Pinochet, the United States Central Intelligence Agency (CIA), and the administration of President Gerald Ford, bided its time before ultimately seizing power.
