The First Conference of the Communist Parties of Latin America took place in Buenos Aires, attracting various leftist groups dedicated to Marxist ideologies from different countries across the continent. Delegates included prominent communists who discussed strategies to enhance revolutionary activities amidst the rising tide of nationalism and liberalism in the region. The primary aim was to solidify alliances among Communist factions to tackle common challenges posed by oppressive political regimes.

One of the highlights of the conference was the formulation of a platform that underscored the necessity of unity among Latin American Communists. The conference incorporated discussions on social justice, the rights of workers, agrarian reform, and anti-imperialism, reflecting the socio-political realities many countries faced during this period. While the assembly focused on internal solidarity, it also drew connections to the broader international Communist movement, most notably aligning with the goals of the Comintern, which sought to promote global socialism.

Furthermore, the conference included a variety of speeches from influential leaders in the Communist movement. Delegates engaged in fierce debates stemming from their individual national contexts, yet there was a collective acknowledgment of the need for a coordinated effort to address the distinct challenges faced in Latin America. The interactions fostered camaraderie and a shared purpose, which subsequently inspired further organizational efforts among leftist groups throughout the continent.
