Geopolitical background (orange) Roman Empires in 476 By the time of emperor
Diocletian (284–305), the idea that the
Roman Empire had grown so large that it would be better managed by two co-ruling emperors, rather than one, had become established. After various divisions were made throughout the 4th century, the empire was firmly and permanently divided into a western and eastern sphere of imperial administration from the death of emperor
Theodosius I (379–395) in 395 onwards. Though modern historians typically use the terms
Western Roman Empire and
Eastern Roman Empire to describe the new political situation, the Romans themselves never considered the empire to have been formally divided, still viewing it as a single unit, although most often having two rulers rather than one. Over the course of the 5th century, the western empire experienced a period of catastrophic decline. Not only were many of the rulers in the west generally lacking in competence, but they also faced enormous problems. In comparison with the eastern provinces, much of the west was more rural, with fewer people and a less stable economy. An increasing number of
Germanic barbarian invasions and settlements throughout the west only added to these issues. In 410, the
Visigoths under
Alaric I had
sacked Rome and in 455, the last western emperor of Theodosius' dynasty,
Valentinian III (425–455), was deposed and murdered. That same year, Rome was
sacked again for the second time in less than fifty years, this time by the
Vandals. The Roman army became increasingly reliant on barbarian mercenaries and after Valentinian's murder, the most powerful barbarian generals, such as
Ricimer ( 418–472), became politically dominant, ruling through proclaiming
puppet emperors. In the twenty years between the death of Valentinian and the accession of Romulus Augustus, eight different emperors ruled in the west. By 475, the western empire was in critical condition. Outside of Italy, authority was only exercised in
Raetia and some regions of
Gaul. The ruling emperor in 475 was
Julius Nepos, who had been in power for less than a year. Nepos had been appointed western emperor in 474 by the eastern emperors
Leo I (457–474) and
Zeno (474–491), but had little real support in the west. In 475, Nepos named
Orestes as a
patrician and
magister militum ('master of soldiers'; effectively commander-in-chief), replacing the previous holder of that office,
Ecdicius. Orestes was a distinguished late Roman figure, once having served as
notarius (secretary) to the
Hunnic king
Attila. As
magister militum, Orestes was tasked by Nepos to lead an army against
Visigoths and
Burgundians,
foederati (barbarian allies of the empire) who were rebelling in southern Gaul. The army given to Orestes by Nepos was multi-ethnic, with many
foederati soldiers. Heeding the grievances of his troops (among other things learning that Nepos had refused requests for land grants ), Orestes defied the emperor's orders and marched on
Ravenna, the capital of the western empire. On 28 August 475, Orestes entered Ravenna with his army and Nepos escaped across the
Adriatic Sea to
Salona in
Dalmatia.
Ancestry and family There is little surviving concrete evidence in regards to Romulus' ancestry beyond Orestes being known to have been a Roman citizen from
Pannonia and sparse information on his immediate family. Orestes' father was a Pannonian Roman officer by the name of Tatulus, and Tatulus had at least one other son, Paulus, who served as a
comes. The name of Romulus' mother is not known, but it might have been Barbaria. The name Barbaria, otherwise rarely attested, may derive either from the
gens (family) Barbii, attested in Roman Pannonia, or it may simply be the feminine version of the name
Barbarius, attested from a few Roman individuals in southern Gaul. Another hypothesis identifies Romulus' mother as Flavia Serena. Romulus' maternal grandfather was a
comes, also by the name of Romulus, attested as alive in 449, when he was sent on an embassy to Attila by the general
Aetius. Orestes and Romulus Augustus' mother married at some point before 449. It is believed that Romulus' mother, and thus perhaps her immediate family, were, like Orestes, from Roman Pannonia. It is possible that Romulus Augustus had older siblings, especially given that Romulus was born several years after the marriage of his parents. In ancient Rome, it was customary for the eldest son to be named after his grandfather. That Romulus was not named Tatulus thus indicates that he was not the firstborn boy. == Reign ==
