Freemasonry is a fraternal organization tracing its origins to the medieval stonemason guilds of Europe. As skilled craftsmen traveled from site to site, they developed secret signs, handshakes, and passwords to identify one another and protect their trade knowledge. Modern Freemasonry preserves these traditions, with rituals and vows of secrecy that may feel irrelevant to some and fuel suspicion among outsiders. But with the internet, secrecy is increasingly difficult to maintain, and this video is no help in that department.
