Born in
Enid, Oklahoma, Ferrill earned a B.A. at the University of Wichita (now
Wichita State University) in 1960. He went on to graduate study at the
University of Illinois at Urbana-Champaign, where he received a master's degree in 1961 and a Ph.D. in 1964. In
The Fall of the Roman Empire: The Military Explanation (1998 ), Ferrill supports the claims of
Vegetius, about increased "
barbarisation" and "
germanisation" helping to cause the collapse of the
Western Roman Empire in the fifth century AD. He asserts that allowing barbarians to settle within Rome's borders, to act as a buffer zone against other barbarians, created friction and led to a decrease in the size of the Roman Empire's Borders. He also states that the Germans were recruited in such large numbers by the Western empire that they in fact changed it from a Roman to a German culture. For example, field army units would not use their helmets, the pilum was replaced, and the standard of drill declined, leading to a lack of military skill within the empire.
