While Europe was still divided into a patchwork of feudal states, there emerged from the East a vast empire that eventually spanned the breadth of Asia. It had been forged under the banner of one of the greatest generals in history, Genghis Khan, and ruled by men who, a generation before, had been simple nomadic tribesmen. Accompanying a BBC2 series, this book traces the rise and fall of the Mongol Empire, describing the great storm that revolutionized the trade of goods and ideas in the medieval world and shattered the Euro-centric view of science and culture. The Mongols introduced the first international currency, built and projected vast highways across the Asian grasslands, and carved out the major political groups of modern Asia. The book gives an essentially Eastern view of these first important contacts between the Orient and the Occident. The author's other books include "All the King's Men", "Shadow Makers" and "In the Sewers of Lvov".
