ABSTRACT
The chapter is a historical review of the experience of the coordination among four South American guerrillas: the Argentinian PRT-ERP, the Chilean MIR, the Uruguayan MLN-Tupamaros and the Bolivian ELN during the second half of the 1970s, mainly in Argentine territory. It focuses on the ideological and social origins of this experience of coordination, reviews its strategy and tactics, and follows its international contacts and networks in Europe and Latin America. Also, it tries to understand this experience in the context of a regional political process lead by an increasing military authoritarian response supported by the United States in the continent.
