ABSTRACT
The wave's first cycle affected countries whose political situations were similar to that of the Cuba of Batista. In several of them, furthermore, the political opponents of the incumbent dictators had been testing classic repertoires of action to topple them for some time. In Brazil, some authors note that since 1962 there were contacts between certain sectors of the Left and Cuba with the aim of promoting a guerrilla war, whose plans were discovered and thwarted. The influence of Cuba and the ideas generated by its revolution were fundamental during the decade, either for the evolution of the Left or for the creation of new political bodies and organizations that mobilized the young and were strategically orientated towards the armed struggle. But with differences with respect to the previous cycle: the armed groups did not appear immediately in the wake of the Cuban Revolution, but some time afterwards at the end of the decade.
