The Order of St. Sylvester

• Time Period: Pre-World War I
• Institution: 1841
• Country: Vatican

The Pontifical Equestrian Order of Saint Sylvester Pope and Martyr, also known as the Sylvestrine Order or the Pontifical Order of Pope Saint Sylvester, stands as one of the five orders of knighthood directly conferred by the Pope, serving as the Supreme Pontiff and head of the Catholic Church, as well as the Head of State of Vatican City. This distinction aims to recognize Catholic laypeople actively engaged in Church life, particularly those who demonstrate dedication through their professional endeavors and mastery of various arts.

In the past, this Order was united with the Order of the Golden Militia. However, Pope Pius X, through his motu proprio on 7 February 1905, titled Multum ad excitandos, split the Sylvestrine Order into two Orders of Knighthood. One retained the name of St. Sylvester, while the other reverted to the ancient name of the Order, namely the Order of the Golden Militia or the Order of the Golden Spur.

The Order acknowledges Catholic individuals deeply involved in Church affairs, especially those who excel in their professional roles and artistic pursuits. Notably, it is also bestowed upon non-Catholics, including prominent figures such as Anglicans, Muslims, and Jews in the UK.
