| Pope Pius XI was born as Achille Ratti (May 31, 1857 - February 10, 1939). He was Pope from February 6, 1922 until February 10, 1939.
He issued the encylical Quas Primas[?] establishing the feast of Christ the King. The main idea here is that the Catholic religion, beliefs, morality, and rule must spread itself to all areas of human living: the home, the city, politics, economics, art, etc.
