Ordo Templi Orientis

Overview

The Ordo Templi Orientis (Order of Oriental Templars, often abbreviated O.T.O.) is an initiatic order organised through a graded system of degrees. Following its restructuring under Aleister Crowley in the early twentieth century, it has functioned principally as a vehicle for the religious system known as Thelema, whose foundational text is Crowley’s The Book of the Law (1904).

The order is led by an Outer Head (the “Frater Superior”) and operates internationally through national grand lodges, local bodies, and ecclesiastical entities of the Ecclesia Gnostica Catholica, its associated church.

Origins & history

The order was established around the turn of the twentieth century by Carl Kellner and Theodor Reuss in Germany, drawing on a mix of Masonic high-degree systems, Rosicrucian currents, and material claimed to derive from contact with esoteric teachers in the East. Aleister Crowley was admitted to the order by Reuss in 1910 and within a few years had been authorised to head its English-speaking work.

Crowley substantially rewrote the order’s rituals to align with Thelema, and after a period of organisational fracture in the mid-twentieth century the present-day O.T.O., with its headquarters in the United States, emerged as the largest of several bodies claiming the lineage.

Beliefs & practices

The order’s religious framework is Thelema, summarised in the maxim “Do what thou wilt shall be the whole of the Law” and accompanied by “Love is the law, love under will.” Members progress through a sequence of initiatic degrees that draw on Masonic structure but are reframed within Thelemic cosmology.

The Gnostic Mass, composed by Crowley in 1913, is the central public ritual of the associated Ecclesia Gnostica Catholica.

Symbols

Recurring symbols include the unicursal hexagram, the lamen of the order, the eye in the triangle (frequently in red), and the sigil of Babalon. The numerological signature 93, derived by Greek isopsephy from the words thelema (“will”) and agape (“love”), is used as a greeting and identifier.

Notable figures

• Theodor Reuss 1855–1923
  Co-founder; Outer Head until 1922

  German occultist, journalist, and Masonic high-degree organiser who, with Carl Kellner, established the order in its early form. Reuss admitted Aleister Crowley to the order in 1910 and authorised him to lead its English-speaking work.

• Aleister Crowley 1875–1947
  Outer Head 1922–1947; principal architect of the modern order

  English occultist, writer, and mountaineer who restructured the O.T.O. as a vehicle for Thelema following his reception of The Book of the Law in Cairo in 1904. The bulk of the order’s present ritual, doctrinal, and ecclesiastical material derives from his pen.

• Karl Germer 1885–1962
  Outer Head 1947–1962

  German-American businessman and longtime financial supporter of Crowley who succeeded him as head of the order. The succession following Germer’s death in 1962 is the source of the principal twentieth-century lineage disputes within the order.

Controversies

Crowley was the subject of sustained tabloid hostility in the British press during his lifetime, much of it inaccurate but some of it grounded in incidents at the Abbey of Thelema in Cefalù, from which he was expelled by the Italian government in 1923.

Modern O.T.O. has been involved in extended litigation over its name, copyright in Crowley’s works, and competing lineage claims, most prominently against the body originally known as the “Society Ordo Templi Orientis” (SOTO) in the late twentieth century. The order’s position on which competing line is the legitimate continuation of Crowley’s order remains disputed by other claimants.
