The Order of Pope Pius IX, also referred as the Pian Order, is a papal order of knighthood originally founded by Pope Pius IV in 1560. Currently, it is the highest honor conferred by the Holy See. The awarding of the order fell into disuse and was re-instituted by Pope Pius IX as a continuation on 17 June 1847.

The Order of the Golden Spur, officially known also as the Order of the Golden Militia, is a papal order of knighthood conferred upon those who have rendered distinguished service in propagating the Catholic faith, or who have contributed to the glory of the Church, either by feat of arms, by writings, or by other illustrious acts. With the death in 2019 of the last remaining knight, Grand Duke Jean of Luxembourg, the order is considered dormant.
