Summary

In 1919, workers in Barcelona, Spain, led by the Confederación Nacional del Trabajo (CNT) and the Regional Labor Confederation of Catalonia (CRT), launched a general strike for economic justice. The strike achieved all its original demands, including the first general guarantee of an eight-hour workday in the world, but was followed by severe military repression and the imprisonment of strike leaders. The campaign demonstrated the power of nonviolent mass action to achieve significant reforms despite a repressive state.

Background

During the early 20th century, Spain experienced political instability and tensions between leftist groups, the military, and the civilian government. In 1919, the CRT and CNT in Barcelona sought to achieve economic reforms including an eight-hour workday, union legalization, and the release of political prisoners, facing opposition from the military and employers.

What happened

On 5 February 1919, eight workers at La Canadiense electrical plant were fired for appealing to the union to join a strike, leading to a walkout by 117 billing office employees. [source: nv-database] After they were blocked from returning to work by police, nearly all La Canadiense workers struck on 8 February, joined by workers from other plants and textile workers. [source: nv-database] The CRT called a general strike, and 100,000 workers joined in Barcelona. [source: nv-database] General Milans del Bosch declared a state of emergency, arrested 3,000 workers and CNT leaders, and attempted to conscript strikers into the army, but this decree was never carried out. [source: nv-database] Newspapers owned by CNT members practiced ‘red censorship’ and refused to print Milans’ demand. [source: nv-database] The strike brought 70% of Catalonia’s production to a halt. [source: nv-database] On 17 March, new liberal officers negotiated with strikers and conceded to all demands, including the eight-hour workday. [source: nv-database] However, military leaders refused to release prisoners, prompting a second strike. [source: nv-database] The military reinstated martial law, arrested the strike committee, and on 31 March CNT secretary Miguel Burgos was killed in prison. [source: nv-database] The second strike was broken by 3 April, and the military expelled civilian officers from Barcelona, gaining local power and momentum towards dictatorship.

Outcome

Verdict: partial.

The initial strike achieved all demands, including the first general guarantee of an eight-hour workday, but military repression intensified, leaders were imprisoned, and the second strike was broken. The outcome is partial because while the immediate goals were met, the campaign did not prevent subsequent repression and the military’s rise to power. [source: nv-database]

  • Coalition-building across unions and sectors amplifies the impact of a strike.
