The Illustrious Royal Order of Saint Januarius (Italian: Insigne Reale Ordine di San Gennaro) is a Roman Catholic order of knighthood founded by Charles VII of Naples in 1738. It was the last great dynastic order to be constituted as a chivalric fraternity, with a limitation to Roman Catholics and a direct attachment to the dynasty rather than the state. The founder of the order, Charles VII of Naples, ruled from 1734 until 1759. The grand magistery of the order is disputed among claimants to the headship of the formerly reigning House of Bourbon-Two Sicilies. Source: Wikipedia (en)
