Pio Heredia Zubía
Who they were
During the Spanish Civil War Catholic people faced persecution from the Republican faction of the war, in part due to their support of the nationalists and the recently abolished monarchy. The Catholic Church venerates them as martyrs. More than 6,800 clerics and other Catholic people were killed in what has been dubbed the Red Terror. As of December 2025, 2,255 Spanish martyrs have been beatified; 11 of them being canonized. For some 2,000 additional martyrs, the beatification process is underway.
