A one-eyed parish priest in postwar Spain built the world’s largest worker-owned cooperative.
José María Arizmendiarrieta arrived in the Basque town of Mondragón in February 1941, a twenty-six-year-old priest assigned to a parish whose previous clergyman had been shot by Francoist forces.1 The town had a population of roughly 7,000, and it had not recovered from the Spanish Civil War. Arizmendiarrieta had lost an eye in a childhood accident and read badly. His parishioners initially asked the bishop to replace him.
He began by founding a technical school in 1943, believing that education was the prerequisite for any economic change.2 In 1955, five graduates of that school created the first industrial cooperative, a small workshop manufacturing paraffin heaters. They called it Ulgor, an acronym from their five surnames.3
In 1959, Arizmendiarrieta and his collaborators founded a cooperative bank, Caja Laboral Popular, which became the financial engine for new cooperative ventures.2 Each cooperative elected its own management team. Pay ratios between the highest and lowest earners were capped, initially at three to one.
The network grew into the Mondragón Corporation, which by 2024 employed over 70,000 workers across more than 250 companies spanning finance, industry, retail, and education.3 It is the seventh-largest company in Spain by asset turnover and the largest business group in the Basque Country.
Arizmendiarrieta held no formal position in any of the cooperatives he helped create. He refused a salary from the movement and traveled by bicycle.1 He died in Mondragón on November 29, 1976. Sixty priests officiated the funeral. In 2015, Pope Francis declared him a "venerable servant of God," the first step in the Catholic canonization process.4
