Pope Pius XI universally instituted the Solemnity of Our Lord Jesus Christ the King in 1925 in his encyclical Quas Primas. At the time, secularism was on the rise, and many Christians, even Catholics, were doubting Christ’s authority, as well as the Church’s, and even doubting Christ’s existence. Pius XI, and the rest of the Christian world, witnessed the rise of dictatorships in Europe, and saw Catholics being taken in by these earthly leaders.

Just as the Feast of Corpus Christi was instituted when devotion to the Eucharist was at a low point, the Feast of Christ the King was instituted during a time when respect for Christ and the Church was waning, when the feast was most needed. In fact, it is still needed today, evidenced by its institution in many other Christian denominations.
