Secret History

A secret history (or shadow history) is a revisionist interpretation of either fictional or real history which is claimed to have been deliberately suppressed, forgotten, or ignored by established scholars. "Secret history" is also used to describe an alternative interpretation of documented facts which portrays a drastically different motivation or backstory from established historical events.

Originally, secret histories were designed as non-fictional, revealing or claiming to reveal the truth behind the "spin": one such example is The Secret History of the Mongols. Secret histories can range from standard historical revisionism with proper critical reexamination of historical facts to negative historical revisionism wherein facts are deliberately omitted, suppressed or distorted.

The quintessential example secret history is the Anecdota of Procopius of Caesarea (known for centuries as the Secret History). It was discovered, centuries after it was written, in the Vatican Library and published in 1623, although its existence was already known from the Suda, which referred to it as the Anekdota ("the unpublished composition"). The Secret History covers roughly the same years as the first seven books of the History of Justinian's Wars and appears to have been written after they were published. Current consensus generally dates it to 550 or 558, possibly as late as 562. It portrays the reign of the Roman Emperor Justinian I to the great disadvantage of the Emperor, the Emperor's wife, and some of his imperial court.

Secret history is sometimes used in a long-running science fiction or fantasy universe to preserve continuity with the present by reconciling paranormal, anachronistic, or otherwise notable but unrecorded events with what actually happened in known history; for instance, in the Star Trek universe, Greg Cox's novels The Eugenics Wars: The Rise and Fall of Khan Noonien Singh cast the devastating Eugenics Wars of the 1990s (still well into the future when first mentioned in an episode from 1967) as shadow wars most people never knew about, in which such real-life events from that era as the Smiling Buddha nuclear test, the Yugoslav Wars, and the 1992 Los Angeles riots were all part of one wider conflict.
