Terminology
The term "Spätantike", literally "late antiquity", has been used by Austrian historians since its popularization by Alois Riegl in the early 20th century. It was given currency in English partly by the writings of Peter Brown, whose survey The World of Late Antiquity (1971) revised the post-Gibbon view of a stale and ossified Classical culture, in favour of a vibrant time of renewals and beginnings, and whose The Making of Late Antiquity offered a new paradigm of understanding the changes in Western culture of the time in order to confront Sir Richard Southern's The Making of the Middle Ages.
The continuities between the later Roman empire, as it was reorganized by Diocletian (r. 284–305), and the Early Middle Ages are stressed by writers who wish to emphasize that the seeds of medieval culture were already developing in the Christianized empire, and that they continued to do so in the Eastern Roman Empire, or Byzantine Empire at least until the coming of Islam. Concurrently, some migrating Germanic tribes such as the Ostrogoths and Visigoths saw themselves as perpetuating the "Roman" tradition. While the usage "Late Antiquity" suggests that the social and cultural priorities of Classical Antiquity endured throughout Europe into the Middle Ages, the usage of "Early Middle Ages" or "Early Byzantine" emphasizes a break with the classical past, and the term "Migrations Period" tends to de-emphasize the disruptions in the former Western Roman Empire caused by the creation of Germanic kingdoms within her borders beginning with the foedus with the Goths in Aquitania in 418.
