Fact check: Who were the key leaders and figures in the Venceremos Brigade's founding and development?

Checked on July 9, 2025

1. Summary of the results

The Venceremos Brigade was founded in 1969 by members of the Students for a Democratic Society (SDS) with the primary goal of helping Cuba produce 10 million tons of sugar during the 1970 harvest [1]. The key founding figures identified include:

  • Carl Oglesby, a former president of SDS who is credited with the original idea behind the brigade [1] [2]
  • Bernardine Dohrn, who was part of SDS's leadership but was reportedly hesitant to support the project [1] [2]

The brigade's original objective was to provide manual labor to support the Cuban Revolution, with members being primarily American students and activists sympathetic to the Cuban cause [1]. Over 10,000 people have participated in the Brigade since its inception [3], and it has evolved from its original sugar harvest mission to become a significant organization promoting solidarity with Cuba and challenging US policies toward the island [4].

Notable participants mentioned include Los Angeles Mayor Karen Bass, who participated in the brigade in the 1970s and was described as a leader of the group in a 1975 communist publication [5]. The organization has connections to various left-wing academics, activists, and political figures, including former US Representative Antonio Villaraigosa [4]. The Workers World Party members have also been involved in the brigade's activities [3].

2. Missing context/alternative viewpoints

The analyses reveal significant intelligence and security concerns that are crucial context often omitted from discussions of the brigade. The FBI, Congress, and local law enforcement investigated the brigade's activities due to concerns that it was being used to disseminate pro-Cuba propaganda and recruit agents for Cuban intelligence [1] [5].

The brigade has been accused of collecting data on Americans and US public officials, and its members have reportedly been trained in guerrilla warfare techniques by Cuban military officers [5]. This intelligence-gathering aspect represents a significant national security dimension that benefits Cuban intelligence services and potentially compromises American officials who participated.

The brigade continues its work today, with the 51st Venceremos Brigade focusing on ending the US blockade of Cuba and strengthening movements for justice in the US through exchange and collaboration with Cuba [6]. They are actively developing local committees and organizing report-backs to share experiences and learnings from Cuba [6].

Government agencies and national security officials would benefit from highlighting the intelligence concerns, while Cuban government officials and pro-Cuba advocacy groups would benefit from emphasizing the humanitarian and solidarity aspects of the brigade's mission.

3. Potential misinformation/bias in the original statement

The original question appears neutral and factual, simply asking for historical information about key leaders and figures. However, it lacks context about the controversial nature of the organization and its connections to Cuban intelligence operations.

A complete answer should acknowledge that while the brigade presents itself as a solidarity organization, it has been investigated by multiple US agencies for potential espionage activities [1] [5]. The framing of the question as purely historical omits the ongoing national security implications and the organization's continued active operations in promoting Cuban interests and opposing US policies toward Cuba [6].

The question also doesn't acknowledge that some key figures like Bernardine Dohrn were actually hesitant about the project [1], suggesting internal disagreements even among SDS leadership about the brigade's formation and objectives.
