William T. Still’s book “New World Order: The Ancient Plan of Secret Societies,” published in 1991, explores the concept of a global conspiracy orchestrated by secret societies throughout history. Still delves into the idea that certain powerful groups, often secretive and influential, have been working towards establishing a centralized world government or a “New World Order.” He traces the historical roots of these ideas, suggesting that various events and movements, including revolutions and financial systems, have been manipulated by these societies to achieve their goals.
