A secret society is a club or an organization whose activities, events, inner functioning, or membership are concealed from non-members. The society may or may not attempt to conceal its existence. The term usually excludes covert groups, such as intelligence agencies or guerrilla insurgencies, that hide their activities and memberships but maintain a public presence. The exact qualifications for labeling a group as a secret society are disputed, but definitions generally rely on the degree to which the organization insists on secrecy, and might involve the retention and transmission of secret knowledge, the denial about membership or knowledge of the group, the creation of personal bonds between members of the organization, and the use of secret rites or rituals which solidify members of the group.
Anthropologically and historically, secret societies have been deeply interlinked with the concept of the Männerbund, the all-male "warrior-band" or "warrior-society" of pre-modern cultures (see H. Schurtz, Alterklassen und Männerbünde, Berlin, 1902; A. Van Gennep, The Rites of Passage, Chicago, 1960).
A purported "family tree of secret societies" has been proposed, although it may not be comprehensive.
Alan Axelrod, author of the International Encyclopedia of Secret Societies and Fraternal Orders, defines a secret society as an organization that:
- is exclusive
- claims to own special secrets
- shows a strong inclination to favor its members.
David V. Barrett, author of Secret Societies: From the Ancient and Arcane to the Modern and Clandestine, has used alternative terms to define what qualifies a secret society. He defined it as any group that possesses the following characteristics:
- It has "carefully graded and progressed teachings".
- Teachings are "available only to selected individuals".
- Teachings lead to "hidden (and 'unique') truths".
- Truths bring "personal benefits beyond the reach and even the understanding of the uninitiated."
Barrett goes on to say that "a further characteristic common to most of them is the practice of rituals which non-members are not permitted to observe, or even to know the existence of." Barrett's definition would rule out many organizations called secret societies; graded teaching is usually not part of the American college fraternities, the Carbonari, or the 19th century Know Nothings.
Because some secret societies have political aims, they are illegal in several countries.Italy (Constitution of Italy, Section 2, Articles 13-28) and Poland, for example, ban secret political parties and political organizations in their constitutions.
Colleges and universities
See also: Collegiate secret societies in North America
Many student societies established on university campuses in the United States have been considered secret societies. Perhaps one of the most famous secret collegiate societies is Skull and Bones at Yale University. The influence of undergraduate secret societies at colleges such as Harvard College, Dartmouth College, the University of Chicago, the University of Virginia, Georgetown University, New York University, and Wellesley College has been publicly acknowledged, if anonymously and circumspectly, since the 19th century.
British Universities, too, have a long history of secret societies or quasi-secret societies, such as The Pitt Club at Cambridge University, Bullingdon Club at Oxford University, and the 16' Club at St David's College. Another British secret society is the Cambridge Apostles, founded as an essay and debating society in 1820.
In France, Vandermonde is the secret society of the Conservatoire National des Arts et Métiers.
Notable examples in CanadaEpiskopon at the University of Toronto's Trinity College, and the Society of Thoth at the University of British Columbia.
Secret societies are disallowed in a few colleges. The Virginia Military Institute has rules that no cadet may join a secret society, and secret societies have been banned at Oberlin College from 1847 to the present, and at Princeton University since the beginning of the 20th century.
While their existence had been speculated for years, internet-based secret societies first became known to the public in 2012 when the secret society known as Cicada 3301 began recruiting from the public via internet-based puzzles. The goals of the society remain unknown, but it is believed that they are involved in cryptography and cryptocurrency.
The only secret society abolished and then legalized is that of the philomaths; it is now a legitimate academic association founded on a strict selection of its members.
