Order of Knight Masons

The Order of Knight Masons is a chivalric Masonic order open to all Master Masons who are also members of a Mark Lodge and a Royal Arch Chapter. Members of the Order meet in Councils of Knight Masons, which are governed by the Grand Council of Knight Masons based in Dublin, Ireland. A member of the Order is known as a Knight Mason.

The Order was formally established in 1923 with the formation of the Grand Council, tasked with preserving and standardizing a set of Masonic degrees that had historically been practiced in various forms across different Masonic bodies. These degrees, collectively known as the Red Cross or Babylonian Degrees, had been transmitted, often in abridged versions, through Royal Arch Chapters and Knights Templar Preceptories since at least the early 18th century. The Irish expressions of these degrees, distinguished by their symbolic depth and ceremonial detail, were consolidated under a single governing authority to ensure their continuation.
