By capturing Vienna, Napoleon changed the course of history. At the time, the Viennese, poorly informed and disoriented, even wanted to believe a false rumor.

The venerable Germanic Roman Empire, which existed since the year 962, did not resist the shock wave. Vincent Haegele, paleographic archivist, curator of the Versailles libraries and prolific historian, takes us on the first stage of a European ride where the Napoleonic conquests took place in 1805 and 1806. He is the author of the book, "Napoleon: The Rise and Fall of the Germanic Empire," published by Simon & Schuster, priced £16.99, with a limited edition of 1,000 copies.
