Secret Societies in 20th Century America

The twentieth century reshaped American secret societies in ways that would have startled their nineteenth-century founders — some organizations swelled to millions of members, others fractured under political pressure, and a few quietly became the subject of congressional investigations. This page examines how fraternal and clandestine organizations defined, adapted, and sometimes reinvented themselves across a hundred years of war, civil rights tension, Cold War paranoia, and cultural upheaval. The scope runs from the Masonic lodges that counted Franklin D. Roosevelt among their members to the Yale senior societies that became shorthand for elite American networking.

Definition and scope

A secret society in the twentieth-century American context is an organized group that restricts membership, requires oaths of confidentiality, and conducts at least some of its activities beyond public view. That definition sounds tidy until it hits the real world, where the line between a fraternal benefit society, a collegiate senior society, and an ideological brotherhood gets genuinely blurry. The Fraternal Order of Eagles, founded in 1898, had over 1.5 million members at mid-century — an organization that large can hardly claim secrecy as its primary feature. Compare that to Skull and Bones at Yale, which taps exactly 15 seniors per year and has done so since 1832, and the contrast clarifies something important: secrecy in American fraternal life operates on a spectrum, not a binary.

The history of secret societies in this country stretches back to colonial charters, but the twentieth century introduced a novel pressure: mass media. Radio, newsreels, and eventually television made ritual secrecy harder to maintain and conspiracy narratives easier to amplify.

How it works

The operating architecture of a twentieth-century American secret society typically rested on four structural pillars:

  1. Tiered membership with degrees — Members advanced through ranks, each requiring new oaths and revealing additional ritual content. Freemasonry's three-degree Blue Lodge system, described in detail at Degrees and Ranks, was the template most other organizations copied or adapted.
  2. Oaths and obligations — Sworn commitments created psychological and social bonds that substituted for legal enforcement. The binding force was reputational, not contractual. See Oaths and Obligations for the historical language involved.
  3. Ritual and regalia — Elaborate ceremonies served dual purposes: they made membership feel meaningful and they raised the perceived cost of departure. The Knights of Columbus, by 1950, had codified four degrees of initiation, each with distinct regalia.
  4. Selective recruitment — Whether by invitation only (Skull and Bones) or by vouched application (most Masonic lodges), controlled entry preserved group cohesion and enforced social homogeneity.

The Bohemian Grove Society offers a useful twentieth-century case study in how these pillars operated outside the traditional lodge structure. The annual July encampment in Monte Rio, California drew Republican and Democratic power brokers alike — Herbert Hoover, Richard Nixon, and Ronald Reagan all attended — yet its organizing principle was exclusivity rather than ritual degree-work.

Common scenarios

Three distinct patterns defined how secret societies functioned in twentieth-century American life.

Elite networking societies — Organizations like Skull and Bones and the Bohemian Grove functioned primarily as career-accelerating networks. Membership signaled trustworthiness to other members and conferred access to business and political relationships unavailable outside the group. The documented membership overlap between Bonesmen and senior positions in the CIA, federal judiciary, and Wall Street banks is extensive enough that journalists including Alexandra Robbins covered it in book-length treatments (Secrets of the Tomb, 2002).

Fraternal benefit societies — The Shriners International and Odd Fellows (Fraternal Order of Odd Fellows) operated hospitals, orphanages, and insurance programs. Shriners Hospitals for Children, established in 1922, grew to 22 facilities across North America by the end of the century — a concrete social infrastructure, not merely a ritual club.

Esoteric and occult orders — Organizations like the Ordo Templi Orientis and the Rosicrucians occupied a smaller but intellectually distinct niche, transmitting philosophical and magical traditions rather than political networks or charitable services. Their membership numbers were modest — the OTO's American membership never exceeded a few thousand at any point in the twentieth century — but their cultural footprint, especially through figures like Aleister Crowley, was disproportionately large.

Decision boundaries

Understanding which organizations merit the "secret society" label — and which merely borrowed its aesthetic — requires distinguishing three categories that are frequently collapsed together in popular coverage.

Documented fraternal organizations with secret elements are groups like Freemasonry and the Knights of Columbus: legally incorporated, publicly acknowledged, with disclosed membership rolls and only specific ritual content kept private. Their secrecy is procedural, not existential.

Elite social clubs with restricted access — Skull and Bones, the Bohemian Grove — are open about their existence but opaque about their proceedings. They are secret in the sense that a locked diary is secret: the object is visible, the contents are not.

Genuinely clandestine organizations that concealed their membership, funding, and purposes from law enforcement occupy a third category, and here the twentieth century produced serious examples. The Senate Select Committee to Study Governmental Operations (the Church Committee), in its 1975-1976 reports, documented that FBI surveillance under COINTELPRO targeted fraternal and political organizations — treating some as subversive regardless of their actual clandestine character.

The conspiracy theories versus documented facts distinction matters enormously when evaluating twentieth-century claims. Declassified records, examined at Declassified Documents on Secret Societies, show that the documented reality of organizations like the Council on Foreign Relations is simultaneously less dramatic and more consequential than popular mythology suggests.
