297 Missing Years: The Story That Says the Middle Ages Were Inserted

On October 4, 1582, in the places that accepted Pope Gregory XIII's new calendar, the next date was October 15. Ten days vanished from the page to bring the calendar closer to the seasons. That detail begins one of Europe's biggest historical rumours: if church authorities could remove ten days by decree, could they once have added whole centuries to the calendar people treat as continuous?

In 1991, German publisher Heribert Illig gave the shocking answer. He said 297 years, from September 614 to August 911, did not happen in the way official history says they did. In his version, medieval record keepers inserted a false block of time into the calendar. The year 2026 could therefore be closer to 1729. Kings, wars, documents and buildings attached to those three centuries do not disappear from books. They become parts of a reconstruction designed to hide a change in timekeeping.
