Mysterious and insular associations are a phenomenon as old as the pyramids. People have formed clandestine organizations, with idiosyncratic rules, rites and practices that have attracted the wealthy, respected, and powerful. From Freemasons and Knights Templar, to Sons of Liberty, Black Hand, and Skull and Bones, these groups have been religious, political, nefarious or just plain silly—and now this special edition from LIFE unlocks the door to these secretive worlds. From those organizations that were hidden behind the Founding Fathers that helped shape the course of history to those that have dabbled in the occult, this beautifully illustrated edition takes you deep inside these fascinating organizations.
