This chapter will examine the transnational militant political culture that emerged from the constriction of political space, socioeconomic crisis, and increased social polarization during the late sixties and early seventies. The elements of this political culture can be briefly described as follows: a Latin Americanist view supported by regional exile experiences; a set of ideas initially critical of the traditional left; and, lastly, a model activist associated with the idealized figures of the revolutionary soldier and the proletarian. This political culture was not merely the result of a number of preformed ideas. Rather it resulted from the interaction of previously held ideas and the political process that these activists had to face. It was in that process that these activists gradually developed a unique political culture, which was built in the course of the regional exchanges that were born of the uncertain historical contingency of local processes that often led them to places that were inconceivable in the mid-1960s.
