Mexican Jesuit Catholic priest Miguel Agustín Pro moments before he was executed during the Cristero War. Pro was charged with bombing and the attempted assassination of former Mexican president Álvaro Obregón. His arrest, lack of trial, and evidential support gained prominence during the Cristero War. Pro was later beatified in Rome by Pope John Paul II as a Catholic martyr killed in odium fidei (in hatred of the faith).
