Miguel Pro was a Mexican Jesuit priest born in 1891 who became a prominent figure during the religious persecution of the Cristero War. After studying in Europe and serving in various locations, he returned to Mexico to minister to Catholics practicing their faith in secret due to strict anti-clerical laws. He was eventually arrested and executed in Mexico City in 1927 on false charges of involvement in an assassination attempt. He is recognized as a martyr for his refusal to abandon his religious duties.
