An advance party of the Cité catholique arrived in Argentina in 1958, in the middle of the Algerian War (1954–62) and after the military deposed Juan Perón in 1955. The Cité Catholique brought to Argentina a doctrine of counter-revolutionary warfare and repression against terrorism, justified as part of Thomist dogmatism. They would thus provide the ideological support of the future "Dirty War" carried out by the Argentine military in the 1970s.
