ABSTRACT
The purpose of this study is to analyze the activities conducted by communist secret services in Uruguay during the first half of the 1960s based on documents archived by the Czechoslovak State Security Service (StB). Czechoslovak spies started to more actively operate in Latin America at the beginning of the 1960s as a reaction to the growing cooperation of the Soviet Bloc with the Cuban government. The residentura in Montevideo was part of a widespread continental network, whose objective was to weaken the U.S. influence on the region and to defend Cuban interests. Thanks to its good working conditions, the residentura of the StB in Uruguay became one of its most important Latin American bases. In order to meet its objectives, Czechoslovak spies cooperated with several people within forces that followed different ideological lines, except with the communists that had direct contact with the KGB. While the importance of the Blancos and the Colorados consisted in gaining information about government policy, cooperation with socialists was useful mainly to make anti-imperialist publications.
