Argentina, 1960 — dissident coup attempt

Argentina (ARG)South America, AmericasNovember 30, 1960

Event Summary

The dataset records an attempted dissident coup in Argentina on 30 November 1960, part of the relentless military pressure on President Arturo Frondizi's constitutional government, which was besieged from multiple directions in a single turbulent year. Alongside the anti-Peronist officers who resented Frondizi's 1958 electoral bargain with the proscribed Peronist movement, this period saw uprisings tied to Peronist and nationalist currents, and the government was operating under the counterinsurgency framework of Plan Conintes. A rising in late 1960 associated with dissident and Peronist aligned elements came within that context and did not unseat Frondizi at the time.

The cumulative weight of the military planteos, however, culminated in his overthrow in March 1962 after he permitted provincial elections that the Peronists won, leading the armed forces to remove him and install the civilian Jose Maria Guido.

Editorial Note

No discrete documentation of a coup attempt precisely on 30 November 1960 was found in accessible English sources this session; the entry records the dataset's coding and the verified context of the besieged Frondizi government, with plotter identity for this specific date unconfirmed, flagged. Pairs with the Argentina 1960-10-15 record in this batch.
