Abstract
In this papper, we will do a travel to the history about Movimiento 19 de Abril, a Colombian guerrilla, and one of their units: the Batallón América. This army was conformed for four groups: M-19 and Movimiento Armado Quintín Lame, Alfaro Vive Carajo, and Movimiento Revolucionario Túpac Amaru. This battalion was a perfect example about the relation of M-19 with national and international guerrillas, and the Socialist International. Across this paper, we will show a primal idea about the internationalism in the Latin American guerrillas, its effects in the posterior history from these guerrillas, the important paper from the Batallón América in their strategy about the cooperation between guerrillas in Colombia and the creation of a transnational revolutionary army in the Latin American continent.
