He Did Not Fear: Xusro Parviz, King of Kings of the Sasanian Empire spotlights Xusro II, the man who almost conquered the Roman Empire in the Roman-Sasanian War of the Seventh Century CE, and examines his historical prominence. This book explores Xusro II who, as a man, was as complex, deep, and complicated as any other historical figure, and compliments Walter Kaegi’s biography of the Roman emperor Heraclius, Xusro II’s contemporary and nemesis. This monograph fully examines the rich cultural and religious landscape of Late Antiquity by analyzing primary sources from the Roman Empire, Zoroastrian tradition, Eastern Christianity, Armenia, Arab Muslim historians, and Persian Muslims, who were trying to find and hold onto their identity in a changing world. He Did Not Fear: Xusro Parviz, King of Kings of the Sasanian Empire fills a missing gap in our knowledge by studying a man who represents a crossroads in Late Antiquity where Persia, the Christian East, the Roman Empire, and Islam all met.
