The year 572 would not, there-
fore, have seemed a propitious one to provoke the Persians, but in that year
Justin refused the first annual tribute under the Fifty-Year Peace negotiated by
Justinian (having evidently paid the three-year tribute due in 568). The Chris-
tians of Persian Armenia had risen in revolt against the attempts by Chosroes to
impose Zoroastrianism on them and appealed to Justin, who not only refused
the tribute due in 572, but also threatened to invade Persia and depose Chosroes
if he persisted in his attempts to turn the Armenians from Christianity. The
Armenian revolt was successful, and they were joined by the Iberian kingdom.
Justin ordered an invasion of Persia. His cousin, Marcian, appointed magister
militum per Orientem,in572 attacked Arzanene, on the southern border of
Persian Armenia, and the next year attacked Nisibis. Once the Persians had
overcome their surprise at the Roman attack, their response was devastating:
they invaded Syria and took Apamea, and then went on not only to relieve
Nisibis, but to besiege and capture the fortress of Dara. The news of the fall
of Dara drove Justin mad, and his consort Sophia took the reins of power.
She negotiated a truce of one year with the Persians for which the Romans
paid 45,000 nomismata (half as much again as had been due); this was later
extended to five years, at the old rate of 30,000 nomismata ayear. But Sophia
could not, as a woman, rule as regent herself, and in December 574 she per-
suaded Justin to make Tiberius, the Count of the Excubitors, Caesar. Although
Justin lived until 578,inthe interim government was in the hands of Sophia
and Tiberius. Sophia is, in fact, a somewhat neglected Byzantine empress. Far
less famous than her aunt Theodora, but unlike her aunt she played a direct
role in Byzantine politics, securing the succession of her husband, and the suc-
cession of Tiberius, whom she vainly hoped to make her second husband. She
is the first empress to appear on Byzantine coins together with her husband.

Theophanes the Confessor, who clearly disliked women with pretensions to
power, paints an ugly picture of Sophia and her meddling in imperial matters,
as he did of Eirene, the first Byzantine empress to rule in her own name. It
may be significant that he has comparatively little to say about Theodora.
Tiberius became emperor in 578, but by then had already effectively been
governing for four years. In many respects he was the reverse of his predecessor:
whereas Justin was financially cautious to the point of being regarded as miserly,
but militarily ambitious, Tiberius bought popularity by reducing taxes, but in
military matters exercised caution. He also called a halt to the persecution of
the Monophysites, on which Justin had embarked. Tiberius quickly realized
that the Empire did not have the resources to engage with its enemies on all
fronts. He thus secured the support of the Avars on the Danube frontier by
