This monograph approaches the topic of the civil and military conspiracies which fundamental intention was to return the power to the General Gustavo Rojas Pinilla, and to avoid the establishment of the National Front, which had been a pass by means of national plebiscite in 1957. The conspiracies that gave to themselves from 1958 to 1961 were planned and carried out by military men sympathetic on Red Pinilla, with an important support of some politicians distinguished from the epoch.
