Among the Germanic tribes who ruled the fragments of the western Roman empire, the Ostrogoths enjoyed the greatest wealth and splendour. Conquering Italy itself from the warlord Odoacer, they inherited the buildings, traditions, and administrative apparatus of imperial rule, and revived the empire in Spain, southern Gaul and the northwest Balkans. Aspects of their history and empire examined here include their ethnic identity in Italy and relations (as Asian heretics) with the Catholic Church; the vicissitudes of sixth century Rome, the monuments of the period in Ravenna; their influence on the economy, settlements, and social structures throughout Italy; the interweaving of society and administration with their internal and external politics; and the history of their Spanish empire. There are also studies of the Goths in eastern Europe before the emergence of the Ostrogoths, and under Hunnic rule. The whole significantly advances an understanding of how medieval Europe evolved from the combination of Roman civilisation with Germanic outsiders.
