Decius (249 - 251 AD)
Family and Background
The emperor Decius, who appears to have been born at
Budelia, a village near Sirmium, somewhere between 190 and
200 AD. His full name was Gaius Messius Quintus Decius
Valerianus and he was consul by 232. He governed Moesia and
Lower Germany between 232 and 235, and was governor of
Nearer Spain under Maximinus. It is asserted by some
sources that he was prefect of the city of Rome in 249, when
he was dispatched to suppress the revolt of Pacatianus in
the Balkans. He succeeded in this, but was then proclaimed
emperor himself. He marched on Rome and became emperor upon
the death of Philip. He was married to a woman of the
Etruscan aristocracy named Herennia Etruscilla, and had two
surviving sons by her when he assumed the throne. The elder
of the pair, Herennius Decius may have been born in the
220s, the other, Hostilianus seems to have been considerably
younger.

Outlines of Policy
The emperor Decius was a curious figure. The evidence of
his actions suggests that he was deeply conservative, that
he was deeply pious, that he possessed a ferocious temper,
and that he was quite stupid. He seems to have yearned for
the days when the empire appeared to be invincible, and he
appears to have cherished the memory of Trajan and the other
emperors who had made Rome great. Thus one of his first
acts after assuming the throne was to take the name Trajan
for himself and to issue an edict ordering all the
inhabitants of the empire to sacrifice to the ancestral gods
for the safety of the state. His vision of the empire may
also be reflected in the remarkable series of
antoniniani which were issued from the mint
at Milan commemorating the deified emperors.
Decius' edict on sacrifices is certainly the best known of
his actions, this is because it had the coincidental effect
of causing serious divisions within the Christian Church.
The edict itself seems to have been straightforward. All
the inhabitants of the empire were required to sacrifice
before the magistrates of their community "for the safety of
the empire" by a certain day (the date would vary from place
to place and the order may have been that the sacrifice had
to be completed within a specified period after a community
received the edict). When they sacrificed they would obtain
a certificate (libellus) recording the fact that they had
complied with the order. Decius himself may have intended
this act to reaffirm the pax deorum, and to reassure people
throughout the empire that the empire was still secure after
the passing of the millennium. For the Christian church it
caused a terrible crisis of authority as various bishops and
their flocks reacted to it in different ways (click here for
more on this--take them to the discussion of the
persecutions). Decius himself may not have been conscious
of any of this. The edict reflects Decius' concern with
tradition, it does not reflect a desire to eradicate
Christianity, and, by the time the edict was taking effect,
Decius had far more serious problems to worry about.
In the east, the unsettled situation that Decius inherited
after the death of Philip remained unsettled, and there was
considerable trouble associated with a figure named
Mariades, who ultimately fled to Persia. While Mariades was
ravaging the eastern provinces, the Goths once again invaded
the empire. In the course of 250 the Carpi pierced the
Dacian frontier and a large band of Goths, evidently under
the command of a king named Cniva, attacked Moesia Decius
moved first against the invaders of Dacia, and then against
Cniva and his followers. But, when he caught up with them
in the area of Beroea, he was heavily defeated.
News of Decius' defeat may have precipitated the short-lived
revolt of Valens and the much more serious revolt of
Priscus. This Priscus appears to have been the governor of
Moesia, and he seized his chance to attack Decius by making
an alliance with the Goths. He handed the city of
Philoppopolis over to them to plunder in the spring of
251.
After sacking Philoppopolis, the Goths withdrew north
through the Dobrudja (nothing is known about Priscus' fate)
with Decius in pursuit. Decius caught up with them in late
May or early June near Abrittus. The Goths appear to have
taken up a position around a marsh in the area, and when the
Romans attacked they became entangled in this swamp. The
result was a total disaster and Decius died on the field.
His body was never recovered.
