Saints of the Cristero War
On May 21, 2000, Pope John Paul II canonized a group of 25 saints and martyrs who had died in the Mexican Cristero War. The vast majority are Catholic priests who were executed for carrying out their ministry despite the suppression under the anti-clerical laws of Plutarco Elías Calles after the revolution in the 1920s.
