The One World Tartarians: The Greatest Civilization Ever Erased From History by James W. Lee is a work of alternative, revisionist history that posits the existence of a massive, technologically advanced, and benevolent global civilization known as "Tartary" (or Tartaria). The book argues that this civilization was intentionally destroyed and scrubbed from history books in the 19th and 20th centuries to facilitate a "new world order". James W. Lee, a former Wall Street analyst, frames this as a "revisionist history" aimed at uncovering the "Greatest Lie" about human history. The author argues that modern history is a fabrication created by a shadowy elite to keep humanity unaware of its potential for free energy and benevolent living.
