The invasion of Europe by the barbarians
J.B. Bury

This book serves as a standard text on the Germanic penetration of the Roman Empire. Bury’s history is indispensable to anyone who seeks to understand the connection between the barbarian migrations of the third to the ninth century. With a focus on military matters, they examine how Germans, Visigoths, Gauls, Ostrogoths and Franks took control of Europe as the power and influence of the Roman Empire waned, and the framework of our modern Europe.
