They ruled for four centuries. They humiliated Rome. They built one of the ancient world's most sophisticated civilizations. And then history forgot them.Between the fall of classical antiquity and the rise of Islam stood a superpower that shaped both - the Sasanian Empire of Persia. At its height, it stretched from the deserts of Arabia to the steppes of Central Asia, from the peaks of the Caucasus to the banks of the Indus. Its armies shattered Roman legions. Its scholars preserved Greek philosophy. Its artists, architects, and administrators built a world so rich and so complex that even after the empire fell, its conquerors could not resist adopting everything it had created.The Sasanian Empire - the story of Persia's last great dynasty, told in full for the first time for the general reader.Follow the rise of Ardashir I, the obscure priest-king from the province of Fars who overthrew the Parthian order and forged an empire from nothing. Witness the reign of Shapur I, who captured a Roman emperor in battle - the only time in history a Roman emperor was taken alive by a foreign enemy. Enter the magnificent court of Khosrow I, the philosopher-king whose sweeping reforms transformed Persia into the most efficiently governed state in the ancient world. And watch in real time as the empire that had stood for four centuries collapsed, with shocking speed, in the space of two decades.This is not only the story of kings and battles. It is the story of the world the Sasanians built - a world of fire temples and silk merchants, of Jewish academies and Christian martyrs, of armored knights and royal rock carvings, of radical social movements and catastrophic civil wars. It is the story of an empire that sat at the crossroads of the ancient world and shaped everything that passed through it.Inside this book you will discover:- How a minor provincial dynasty overthrew the Parthian Empire and invented a new Persian identity from the ground up- The sophisticated administrative and legal machinery that governed millions across forty provinces for four centuries- The role of Zoroastrianism as state religion and how Christians, Jews, Manichaeans, and others navigated life inside a Zoroastrian empire- The endless wars with Rome and Byzantium that defined both civilizations and ultimately exhausted them both- The Sasanian Empire's central place in the Silk Road economy and its diplomatic relationships stretching from China to Ethiopia- The revolutionary Mazdakite movement that nearly overturned the entire social order a century before the empire fell- How Sasanian administrative systems, court culture, art, and philosophy survived the Arab conquests and flowed directly into early Islamic civilization- The women, scholars, merchants, and ordinary people whose lives gave the empire its texture and humanity- And much more...Drawn from the latest archaeological discoveries, newly translated primary sources, and decades of specialist scholarship, The Sasanian Empire brings one of history's most important and least known civilizations to vivid life. It is essential reading for anyone who wants to understand how the ancient world became the medieval world - and how the Middle East was shaped into the region we know today.The Sasanian Empire was not a footnote between Rome and Islam.
