In the 6th century AD, during the reign of Emperor Justinian, the Roman Empire experienced an extraordinary resurgence, reconquering lands - including Italy, North Africa and Rome itself - that had been lost to the 'barbarians' a century before. Leading these campaigns, a brilliant Roman general named Flavius Belisarius - a skilled tactician, inspirational leader, pragmatic and humane. This is the story of those campaigns, as recorded by Procopius, an eyewitness to many of them, as well as other ancient historians, texts, and archaeological remains.
