Taking readers on a global journey through human history, historian Natasha Tidd examines how lies can change the world around us, from Julius Caesar's deceptive PR machine to the cover ups that caused Chernobyl. From forgeries that created centuries worth of conflict and domination, such as The Donation of Constantine, the Protocols of Zion and the mysterious Testament of Peter the Great, to mass political and press cover ups including Britain's Boer War concentration camps, a Pulitzer Prize winning whitewash of the Ukraine Famine and France's infamous Dreyfus Affair. Alongside these are examinations of how our retellings of history can turn fiction into fact, including The Spanish Inquisition's deceitful legacy and the demonisation of Chinese Empress, Wu Zetian. Plus, an in-depth look at how historic lies can still impact our lives today, such as the deadly legacy of America's Tuskegee Experiment.
