The present work tries to construct the history of the international activity of the Popular Liberation Army (EPL) putting emphasis in Central America and the Caribbean. This Colombian guerrilla organization with a Maoist orientation, in its beginnings, between 1986 and 1990 developed an intense diplomatic activity in several countries of the region, generating political interactions with state and non state agents, specially in Cuba and Nicaragua, demonstrating hereby, the direct influence that the revolutionary Central American processes had on the Colombian insurgency. In addition, with this article we strive to contribute to the construction of the history of the international relations of non state Colombian actors.
