rule of barbarian chieftains in the last quarter of the 5th century, it deepened further afterward, and had lasting consequences for the medieval history of Europe. Throughout the 5th century, Western emperors were usually figureheads, while the Eastern emperors maintained more independence. For most of the time, the actual rulers in the West were military strongmen who took the titles of magister militum, patrician, or both, such as Stilicho, Aetius, and Ricimer. Although Rome was no longer the capital in the West, it remained the West's largest city and its economic center. But the city was sacked by rebellious Visigoths in 410 and by the Vandals in 455, events that shocked contemporaries and signaled the disintegration of Roman authority. Saint Augustine wrote The City of God partly as an answer to critics who blamed the sack of Rome by the Visigoths on the abandonment of the traditional pagan religions. In June 474, Julius Nepos became Western Emperor but in the next year the magister militum Orestes revolted and made his son Romulus Augustus emperor. Romulus, however, was not recognized by the Eastern Emperor Zeno and so was technically an usurper, Nepos still being the legal Western Emperor. Nevertheless, Romulus Augustus is often known as the last Western Roman Emperor. In 476, after being refused lands in Italy, Orestes' Germanic mercenaries under the leadership of the chieftain Odoacer captured and executed Orestes and took Ravenna, the Western Roman capital at the time, deposing Romulus Augustus. The whole of Italy was quickly conquered, and Odoacer was granted the title of patrician by Zeno, effectively recognizing his rule in the name of the Eastern Empire. Odoacer returned the Imperial insignia to Constantinople and ruled as King in Italy. Following Nepos' death Theodoric the Great, King of the Ostrogoths, conquered Italy with Zeno's approval. Meanwhile, much of the rest of the Western provinces were conquered by waves of Germanic invasions, most of them being disconnected politically from the East altogether and continuing a slow decline. Although Roman political authority in the West was lost, Roman culture would last in most parts of the former Western provinces into the 6th century and beyond. The first invasions disrupted the West to some degree, but it was the Gothic War launched by the Eastern Emperor Justinian in the 6th century, and meant to reunite the Empire, that eventually caused the most damage to Italy, as well as
