Accession Justinian I had several nephews but seems to have never appointed an heir. On the night of 13 November 565 – 14 November 565, Justinian I lay on his deathbed. Justin was his
kouropalates and thus a viable heir within the
Great Palace of Constantinople. He managed to gain the support of the
Senate and was proclaimed emperor in the palace before the other members of the
Justinian Dynasty were notified. According to
John of Biclaro, the murder was carried out by the supporters of Sophia. Evagrius claims that the head of the deceased was sent to the imperial couple who spitefully kicked it around, a detail likely exaggerated by Evagrius. In 568,
Narses was removed from his position as prefect of
Italy. According to
Paul the Deacon, Sophia sent a message to the senior general that she had a more suitable position for a
eunuch like him, as an overseer of the weaving girls of the
gynaikonitis (women's quarters). Narses chose to retire to
Naples, instead of returning to Constantinople as Justin had ordered him to do and invited the Lombards to invade. But the evidence for this conflict is deemed unreliable by some historians.
Financial policy Sophia was involved in the financial policies of Justin. Having inherited an exhausted treasury, they set about repaying the various debts and loans of Justinian to bankers and money-lenders. According to
Theophanes the Confessor, Sophia was in charge of the debt repayments, and this act gained her contemporary praise. The imperial couple tried to reduce expenses and increase treasury reserves. Evagrius, John of Ephesus,
Gregory of Tours, and Paul the Deacon mention this while accusing both Justin and Sophia of greed. After the death of Justin, Sophia and emperor
Tiberius II Constantine were said to have clashed over financial policies.
Religious policy In 569, Justin and Sophia together reportedly sent a relic of the
True Cross to
Radegund. The event was commemorated in
Vexilla Regis by
Venantius Fortunatus. They also sent relics to
Pope John III in an attempt to improve relations: the
Cross of Justin II in the
Vatican Museums, a
crux gemmata, and a
reliquary of the
True Cross perhaps given at this point, has an inscription recording their donation and apparently their portraits on the ends of the arms on the reverse. This led to creation of poems by
Venantius Fortunatus, which referred to Justin and Sophia as the new Constantine and the new Helena, and indicating Sophia's major role in the presentation of the relic. For the
Monophysites, the religious policy of the couple was controversial. During their reign, they attempted but failed to reconcile
Chalcedonian and
Monophysitic Christianity, which ended in renewed persecution of the latter. Meanwhile, their own beliefs were still in question. John of Ephesus himself was imprisoned during this persecution, presumably contributing to the hostile tone to Justin and Sophia in his writings. ==Regent (573–578)==
