The Masonic Order of the Red Cross of Constantine was first organised in the UK by Charles Shirreff around 1780 and re‑established in 1804 by Waller Rodwell Wright. After limited activity, Grand Imperial Conclave was revived in 1865, leading to steady growth across the English‑speaking world. The Order belongs to the “East and West” class of Initiatory Rites and comprises three degrees; Knight, Priest‑Mason, and Prince‑Mason;reflecting stages of spiritual progression centred on Constantine’s conversion. Candidates must be Royal Arch Masons and members of the Appendant Orders.
