History's greatest tour guide is back. And he's ringing the changes. In a contest of change, which century from the past millennium would come up trumps? Imagine the Black Death took on the female vote in a pub brawl, or the Industrial Revolution faced the internet in a medieval joust - whose side would you be on? In this hugely entertaining book, celebrated historian Ian Mortimer takes us on a whirlwind tour of Western history, pitting one century against another in his quest to measure change. We journey from a time when there was a fair chance of your village being burnt to the ground by invaders, and dried human dung was a recommended cure for cancer, to a world in which explorers sailed into the unknown and civilisations came into conflict with each other on an epic scale. Here is a story of godly scientists, shrewd farmers, cold-hearted entrepreneurs and strong-minded women - a story of discovery, invention, revolution and cataclysmic shifts in perspective. Bursting with ideas and underscored by a wry sense of humour, this is a journey into the past like no other.Our understanding of change will never be the same again - and the lessons we learn along the way are profound ones for us all.
