What Happened During the May Days in Barcelona in 1937?

By Anna Duncan

The May Days in Barcelona in 1937 were a significant event during the Spanish Civil War. This period of intense conflict and political tension took place between May 3rd and May 8th, and it had a profound impact on the course of the war and the political landscape of Catalonia.

The Background

In order to understand what happened during the May Days, it is important to have some background knowledge about the political climate in Barcelona at that time. The Spanish Civil War began in 1936, pitting the Republican government against General Francisco Franco’s Nationalist forces.

Within the Republican side, there were various factions with differing ideologies. One such faction was the Workers’ Party of Marxist Unification (POUM), which advocated for a more revolutionary approach to socialism. Another major faction was the Unified Socialist Party of Catalonia (PSUC), which was aligned with the Soviet-backed Communist Party.

The Trigger

The May Days were triggered by a series of events that led to an escalation of tensions between these two factions. On May 3rd, members of the PSUC and their allies launched an attack on key buildings controlled by the POUM, accusing them of being Trotskyist conspirators. This attack led to street battles throughout Barcelona as supporters of both factions clashed.

Violence and Repression

During these days, violence and repression became widespread. The Republican government, fearful of a potential anarchist uprising, declared a state of emergency and began arresting members of anarchist groups such as the CNT-FAI. The streets were filled with armed militias from different factions, leading to chaotic scenes and numerous casualties.

  • Rumors Spread: Rumors circulated that POUM leaders were planning a coup against the Republican government or collaborating with Franco’s forces. These rumors further fueled the tension and violence on the streets.
  • Newspaper Censorship: The government imposed strict censorship on newspapers, controlling the flow of information and shaping public opinion.
  • Foreign Involvement: The May Days also saw the involvement of foreign actors. Soviet-backed communist forces supported the PSUC, while anarchists and Trotskyists received support from international volunteers who sympathized with their cause.

The Aftermath

The May Days had significant consequences for Catalonia and the wider Spanish Civil War. The POUM was outlawed, its leaders were arrested, and its newspaper was shut down. This event marked a turning point in the war, as it demonstrated the growing influence of Stalinist communism within Republican ranks.

The May Days also led to a loss of unity among Republican forces, weakening their ability to resist Franco’s advance. The conflict further polarized political factions, making it difficult for them to work together effectively against their common enemy.

In conclusion, the May Days in Barcelona in 1937 were a tumultuous period during the Spanish Civil War. The clash between different factions within the Republican side resulted in violence, repression, and political upheaval. It is a stark reminder of how internal divisions can weaken a movement fighting for a common cause.
