# Secret society

A secret society is an organization about which the activities, events, inner functioning, or membership are concealed. The society may or may not attempt to conceal its existence. The term usually excludes covert groups, such as intelligence agencies or guerrilla warfare insurgencies, that hide their activities and memberships but maintain a public presence.
Secret societies may be community-based or associated with colleges and universities. These societies exist in countries around the world.

## Definitions

The exact qualifications for labeling a group 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 of membership or knowledge of the group, the creation of personal bonds between members of the organization, and the use of secret rites or rituals.
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.
Historian Richard B. Spence of the University of Idaho offered a similar three-pronged definition:
* The group's existence is usually not kept secret, but some beliefs or practices are concealed from the public and require an oath of secrecy and loyalty to learn.
* The group promises superior status or knowledge to members.
* The group's membership is in some way restrictive, such as by race, sex, religious affiliation, or invitation only.
Spence also proposes a sub-category of "Elite Secret Societies" (composed of high-income or socially influential people) and notes that secret societies have a frequent if not universal tendency towards factionalism, infighting, and claiming origins older than can be reliably documented. Spence's definition includes groups traditionally thought of as secret societies (Freemasons and Rosicrucians) and other groups not so traditionally classified such as certain organized crime cabals (the Mafia), religious groups (Order of Assassins and Thelema) and political movements (Bolsheviks and Black Dragon Society).
Historian Jasper Ridley says that Freemasonry is "the world's most powerful secret Society".
The organization "Opus Dei" (Latin for "Work of God") is portrayed as a "secret society" of the Catholic Church. Critics such as the Jesuit Wladimir Ledóchowski sometimes refer to Opus Dei as a Catholic (or Christian or "white") form of Freemasonry. Other critics label Opus Dei as "Holy Mafia" or "Santa Mafia"
The National Christian Association (1868–1983) is an example of an organization opposed to secret societies.

## Realms
### Politics

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

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, Cornell University, Florida State University, Dartmouth College, Emory University, 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 have a long history of secret societies or quasi-secret clubs, such as The Pitt Club at Cambridge University, Bullingdon Club at Oxford University, the Kate Kennedy Club, The Kensington Club and the Praetorian Club at the University of St Andrews, 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. Not all British universities host solely academic secret societies; both The Night Climbers of Cambridge and The Night Climbers of Oxford require both brains and brawn.
In France, Vandermonde is the secret society of the Conservatoire National des Arts et Métiers.
Notable examples in Canada include Episkopon 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.
Confraternities in Nigeria are secret-society-like student groups within higher education, some of which have histories of violence and organized crime. The exact death toll from confraternity activities is unclear. One estimate in 2002 was that 250 people had been killed in campus cult-related murders in the previous decade, while the Exam Ethics Project lobby group estimated that 115 students and teachers had been killed between 1993 and 2003.
The Mandatory Monday Association is thought to operate out of a variety of Australian universities including the Australian Defence Force Academy. The Association has numerous chapters that meet only on Mondays to discuss business and carry out rituals.
The only secret society abolished and then legalized is that of The Philomaths, which is now a legitimate academic association founded on a strict selection of its members.

### Internet

While their existence had been speculated for years, Internet-based secret societies first became known to the public in 2012 when Cicada 3301 began recruiting from the public via Internet-based puzzles. The goals of the society remain unknown, but it is believed to be involved in cryptography.

## Opposition

The Catholic Church strongly opposed secret societies, especially the Freemasons. It did relent somewhat in the United States and allowed membership in labour unions and the Knights of Columbus, but not the Masons. Some Christian denominations continue to forbid their members from joining secret societies in the 21st century, such as the Allegheny Wesleyan Methodist Connection and Seventh-day Adventists.
