Secret societies have captured the imagination of the public for centuries. Many of these groups are thought to be ancient, mysterious gatherings of powerful men who get together and tip the balance of world power in their own favor.

These organizations, which have developed their own rituals and require membership oaths, exist for numerous reasons and have popped up over the centuries. Not just anyone can be a member of these groups. Many restrict admittance based on gender, religion, or occupation. Some seek power for their members, while others are dedicated to charity. Whatever their purpose, these organizations are thought to have significant influence on the outside world, largely because of the powerful people known to be members.

24/7 Wall St. reviewed historical records and media sources to determine the most powerful secret societies still in existence today.

Perhaps the group that pops into most people’s heads when they hear the words “secret society” is the Illuminati. However, he actual Illuminati, formed in Germany in the 18th century, only existed for a few years before disappearing. The legend of the Illuminati as an all-powerful secret order, which includes famous people like Beyoncé, comes from Playboy Magazine.

Two writers for the publication sent fake letters supposedly from readers to the magazine to stir up public fervor about the Illuminati’s role in society, and those falsified letters are the reason people believe the group is still in power today — or maybe that’s just what they want us to think.

However, there are secret societies whose members have wielded considerable influence and power that are very real and still operate to this day. Freemasons are well known worldwide, with an estimated 3.6 million members — more than 1 million of whom are in the U.S. The group has included influential figures such as George Washington, Ben Franklin, J. Edgar Hoover, Benedict Arnold, and more.

Though secret societies likely make people think of old men sitting over grand wooden tables, the group that may be able to claim the most influential alumni in the U.S. is made up of college students. The Skull and Bones society, open only to seniors at Yale University, has a long list of powerful business leaders and politicians who were once members. Presidents William Taft, George H.W. Bush, and George W. Bush were all members.

Many secret societies focus more on helping the world than its members. Groups like the Odd Fellows and the Seven Society have stated missions to help those in need. Other organizations, such as The Loyal Order of Moose and the Ancient Order of United Workmen, are made up of working class people and serve as a union of sorts, advocating for their members’ interests and helping them obtain health or life insurance.

Secret societies date back hundreds of years, with one of the oldest examples being the Knights Templar. The group of crusading warriors, founded in 1118, had the stated mission of protecting Christian pilgrims and defending the Holy Land against Muslim armies. The Knights Templar disbanded in the early 14th century, but many secret societies still aim to promote its religious values.

Though Opus Dei was vilified in the film “The Da Vinci Code,” the Catholic organization’s stated goal is to encourage people to be “close to Christ, and making Him known to others.” Other groups like the Ancient Order of Hibernians work to preserve and defend their religion.

There is still much we don’t know about these societies, given their secretive nature. In fact, there is always a chance other influential groups were omitted from this list because their secretive nature has kept them out of the public eye.

In order to determine the most powerful secret societies, 24/7 Wall St. reviewed historical records, information from the societies, and media sources to find societies with restrictive membership guidelines. To be considered, the society must still be in operation, meet regularly, adhere to traditions including an oath, and have some membership base located within the United States.

Opus Dei is a Catholic group with 80,000 clergy and lay members who claim to find God in everyday life.

This encountered some opposition from alumni until Scroll and Key member and then-Yale President A. Bartlett Giamatti said he would not set foot in the club until women were admitted.
