For whatever reason, these groups cannot exist in the public eye. Whether this is because they are breaking the law, operating in a clandestine fashion, or because they fear retribution from other secret societies, they were often the only ones who knew. At the time, their ability to remain secret often meant the difference between life and death. Now, many years later, we can look back on these secret groups and try and lean exactly what they represented. In this book, we will look into murder, assassinations, political coups, and events which left a huge impact on the history of the world. Behind some of the most tragic events in human history, these secret societies have operated in the shadows. Their influence has been felt in every corner of the world. Secrecy is not endemic to one country or one continent. Instead, all humans have a small part of themselves which craves the secrecy afforded to these groups. But only some of us manage to bond together to form societies such as these. That's why they are remembered as the most mysterious secret societies in the world.
