During the
later history of the Roman Empire the top job
became too much for one man to handle, with the result that the Empire was
governed at various times by two or more Emperors. Gratian, who reigned from
375 to 383, was one of many such joint Emperors.
Flavius
Gratianus was born on 18th April 359 at Sirmium in Pannonia (a Roman
province that covered parts of modern Austria, Hungary, Slovakia and several
former Yugoslav republics). His father was Emperor Valentinian I and his mother
Marina Severa, who was later divorced by Valentinian, probably in 370.
On his
elevation to Emperor, Valentinian had requested that his brother Valens should
rule jointly with him, the latter taking control of the eastern part of the
Empire while Valentinian ruled in the west. This arrangement, which had also
been made by Diocletian in the previous century, was to become a familiar
pattern until the eventual collapse of the Western Empire
in the 5th century.
Gratian’s
early years
Gratian’s first
public office was that of consul in 366. Two (sometimes more) consuls were
appointed for one-year terms, this being an office that had its origins in
Republican Rome but had long been merely an honorary position. As Gratian was
aged seven at the time this was simply an acknowledgment of his high status as
the Emperor’s son.
He accompanied
his father on campaign in Gaul in 367, and it
was on this campaign that Valentinian fell seriously ill and there was concern
among his courtiers about who would succeed him if he died. Discussions were
held without either Valentinian or his brother being consulted, which many Emperors
would have regarded as treasonable behaviour. However, when Valentinian
recovered, his only action was to appoint his son Gratian as “Augustus” (i.e.
Emperor-in-waiting), thus indicating who his successor would be.
Despite the
boldness of this move, there were many people who doubted whether this was the
best thing to do. Had the young Gratian shown signs of being suited for high
office, possibly to be attained within only a few years, the senior officials
might have had their fears assuaged, but this was not the case. Gratian
appeared to have little interest in military matters and his father had great
difficultly in persuading the army that his son had the qualities of a
potential Emperor. He took steps to educate Gratian for his future role by
appointing the poet and rhetorician Ausonius as his tutor, although this seems
a strange choice given that a military-style education would have been more
appropriate. Gratian clearly found Ausonius to be a tutor he could get on with,
as he appointed the poet to the consulship when he became Emperor.
Gratian
married in 374, his wife Constantia being the daughter of a former Emperor
(Constantius II). She died in 383, shortly before Gratian himself.
Gratian as
Emperor
When
Valentinian died on 17th November 375, Gratian was declared Emperor
as his father had decreed, but this did not please everyone, and particularly
not the army commanders in the Balkan region. They sought a leader, albeit only
a nominal one, who would allow them to be the real force in the part of the
empire that they controlled, namely the eastern part of the Western
Empire. Within five days of Valentinian’s death, his son (by his
second wife Justina), also called Valentinian, was declared Emperor by the army
of that region.
Gratian was
therefore left as one of three Emperors, having jurisdiction over
Gaul, Spain
and Britain.
The provinces in Italy,
Africa and Illyricum were nominally governed
by Emperor Valentinian II, although he was not yet five years old at the time
of his accession. The Eastern Empire continued
to be ruled by Valens, who was fully occupied in repelling invasions by the
Goths.
Despite the
fact that the decision to appoint his half-brother as co-Emperor was taken
without his consent, Gratian appears to have accepted it without too much fuss,
and even took steps to help the young Emperor with his education.
Gratian had
problems of his own to contend with, namely incursions by the Alamanni tribe into
what is now southern Germany. Although the situation was peaceful at the time
of his accession, the Alamanni needed to be watched, which presented a problem
when a request came from Valens in 376 for help to repel the Goths in the east.
Gratian was willing to help, but his chief general, Merobaudes (who had also
been mainly responsible for the appointment of Valentinian II), disobeyed
Gratian’s orders and held some of the legions back in order to guard the border
against the Alamanni. The fact that Merobaudes could get away with this shows
that Gratian was not strong-willed enough for the job of Emperor, although the
actions of Merobaudes were probably correct under the circumstances.
In late 377
Gratian prepared to set off east to help his uncle against the Goths, but this
was the signal the Alamanni had been waiting for. They invaded in February 378
but the legions left in place by Merobaudes were able to deal with the threat,
with some 30,000 Alamanni being killed in battle at Argentovaria (near Colmar, France).
With his own
borders secure, Gratian could now provide the assistance that Valens had asked
for, but the latter seems to have changed his mind and decided to take on the
Goths without waiting for his young nephew (still only 19 in 378) to arrive. The
result was a devastating defeat at Adrianople
at which two-thirds of the Roman army, and Valens himself, were killed.
Gratian was
now left as the senior Emperor in the whole of the Roman
Empire. However, he clearly needed help and he called on a Spanish
general, Theodosius, to assist him. This was an interesting choice, because
Theodosius’s father, also called Theodosius, had fallen foul of Merobaudes
during the reign of Valentinian I and had been executed following a trumped-up
charge of treason. The appointment may have been partly a move by Gratian to
assert himself against Merobaudes.
Theodosius
allowed himself to be declared Eastern Emperor by his troops, and Gratian did
not oppose this move. It at least allowed him to carry on with the more
peaceful life of being Western Emperor.
Gratian, who
like all the Emperors since Constantine
was nominally Christian, now interested himself in Church affairs. In 381 he moved his capital from Trier (in Gaul) to Milan,
where Ambrose had earlier been appointed bishop with the Emperor’s help.
Gratian involved himself in the debate between orthodox Christians and the
“heretics” who followed the teachings of Arius. He was persuaded by Ambrose to
call a council of bishops to debate the matter, and this convened at Aquileia (in northern Italy) in September 381. Ambrose
made sure that the decision that was made favoured his position and had the Emperor’s
backing.
Gratian
continued to support Theodosius in the east, by sending troops when needed, but
the support was not reciprocated. In 383 the commander of the British garrison,
Magnus Maximus, revolted against Gratian and invaded Gaul,
where he was supported by Merobaudes. Theodosius indicated that he would not
oppose the revolt, and Gratian was subsequently defeated and forced to flee.
His pursuers caught up with him at Lyons
and he was killed on 25th August 383, aged 24.
Gratian’s
career as Emperor was not a particularly distinguished one as he simply did not
have the qualities needed to be a strong Emperor. In his defence it could be
pointed out that, during the turbulent times of the later Roman
Empire, there were very few men who did.
