Summary

In the summer of 1963, Asturian coal miners in Spain went on strike for 60 days to demand better working conditions, higher wages, and the right to direct representation by their own delegates, rejecting Franco’s vertical union structure. The strike began spontaneously in one mine and spread to involve 40,000 to 50,000 workers across Spain, but did not reach major industrial centers. Despite brutal repression and no immediate gains, the campaign strengthened the democracy movement and continued until Franco’s death in 1975.

Background

The Asturian miners were challenging the dictatorship of General Francisco Franco, who imposed a vertical union structure that lumped workers and managers together. The miners sought better working conditions, one month paid vacation, wage increases to keep pace with rising costs, and the right to strike. The strike was inspired by a similar but more economically focused strike in 1962.

What happened

The strike began spontaneously in the last week of July 1963 when one coal mine in Asturias walked out, and other mines quickly joined in solidarity [source: nv-database]. Each mine shaft elected a delegate to lead secret meetings and coordinate the strike [source: nv-database]. The strikers sent a group of miners suffering from silicosis to the central government in Madrid as a protest against the regime’s unions [source: nv-database]. Solidarity actions included fishermen in Bilbao working extra shifts to supply fish, miners sharing farmed crops, and small businesses providing food [source: nv-database]. Franco responded immediately with lockouts and attempted to reopen mines every Monday, but managers reported insufficient workers [source: nv-database]. The regime used police violence, arrests, imprisonment, and torture, which was hidden from the public [source: nv-database]. A trial of five anarchist militants, two of whom were garroted, was used to discourage further participation [source: nv-database]. The strike ended after 60 days at the end of September 1963, with 40,000 to 50,000 workers having participated, but it did not spread to Catalonia, the Basque country, or Madrid [source: nv-database].

Key people & organizations

  • Union alliance
  • Popular Liberation Front
  • General Francisco Franco

Outcome

Verdict: partial.

No immediate demands were achieved, but the campaign survived and grew, with similar struggles continuing until Franco’s death in 1975. The strike provided momentum to the democracy movement and demonstrated the miners’ role in challenging Francoism. [source: nv-database]

Lessons

  • Solidarity networks with external groups (e.g., fishermen, small businesses) can sustain a strike when financial resources are exhausted.
  • Secret delegate structures can maintain organization and leadership under repressive regimes.
  • Even without immediate success, sustained nonviolent action can build long-term momentum for political change.
