Secret societies throughout history

Among the earliest secret societies of which historical evidence exists were the mystery religions of ancient Egypt, Greece, and Rome, which had secret rites, initiations, and revelations of still more ancient wisdom. Among these were the cult of Dionysus, the keepers of the Eleusinian and Orphic mysteries, and the Pythagorean brotherhood. Whereas the mysteries employed secrecy to guard religious truths, other groups have been forced to adopt secrecy to escape or survive suppression and persecution. This was the case of the early Christians in pagan Rome and, in their turn, of various groups deemed heretical by the Roman Catholic Church in the Middle Ages. So widespread were these groups that the church created the Inquisition to hunt them down and prosecute their members.
