Intermittent wars have occurred between the Lombards,…

Gao Wei succeeds his father Emperor Wucheng as ruler of the Chinese Northern Qi Dynasty.

Wu Cheng Di becomes a regent and Grand Emperor.

The Avars, after vainly trying to force the Danubian border when the new emperor Justin II denies them both entry and wage, renew their ride to Thuringia, taking it from the Franks in 565, but are stopped here.

Procopius of Caesarea probably retires to Constantinople after Belisarius’ disgrace.

In the Wars, he narrates Justinian's achievements to 553.

In The Buildings, completed two years later, Procopius writes a further paean to Justinian for his public works.

In the posthumously published and highly scurrilous Secret History, Procopius, who dies around 565, claims to reveal information about the emperor's personality and policy that he could not present in the earlier books because he feared the emperor’s wrath.

He alleges that the emperor’s late wife, Theodora, was formerly and actress and a prostitute.

Justinian, who had always had a keen interest in theological matters and actively participated in debates on Christian doctrine, has become even more devoted to religion during the later years of his life.

When he dies, on November 14, 565, he leaves the empire exhausted by his wars and public spending, but enriched by his law code and monuments.

Justinian's body is entombed in a specially built mausoleum in the Church of the Holy Apostles (the tomb will be desecrated and robbed during the pillage of Constantinople in 1204 by the Latin States of the Fourth Crusade).

Along with Justin, the kouropalates, another of the late emperors’ nephews, Justin, son of the late Germanus, is the leading contender for the vacant throne, due to his titles and reputation as a commander, as well his army's proximity to the imperial capital.

The former, however, is already present at Constantinople, and can count on the support of the Senate, and especially of Patriarch John Scholasticus and the Count of the Excubitors Tiberius (the future Tiberius II), whom he had helped secure his post.

Callinicus, the praepositus sacri cubiculi, seems to have been the only witness to his dying moments, and later claimed that Justinian had designated "Justin, Vigilantia's son" as his heir in a deathbed decision.

Modern historians suspect Callinicus may have fabricated the last words of Justinian to secure the succession for his political ally, who is the son of Justinian’s sister Vigilantia, and married to Sophia, the niece of the late Empress Theodora.

In any case, Callinicus starts alerting those most interested in the succession, originally various members of the Byzantine Senate.

Then they jointly inform Justin and Vigilantia, offering the throne.

Justin accepts after the traditional token show of reluctance, and with his wife Sophia, he is escorted to the Great Palace of Constantinople.

The Excubitors block the palace entrances during the night, and early in the morning, John Scholasticus, Patriarch of Constantinople, crowns the new Augustus.

Only then is the death of Justinian and the succession of Justin publicly announced in the Hippodrome of Constantinople.

Both the Patriarch and Tiberius, commander of the Excubitors, had been recently appointed, with Justin having played a part in their respective appointments, in his role as Justinian's curopalates.

Their willingness to elevate their patron and ally to the throne is hardly surprising.

In the first few days of his reign Justin pays his uncle's debts, administers justice in person, and proclaims universal religious toleration.

Contrary to his uncle, Justin relies completely on the support of the aristocratic party.

Proud of character, and faced with an empty treasury, he discontinues Justinian's practice of buying off potential enemies.

Immediately after his accession, Justin halts the payment of subsidies to the Avars, ending a truce that has existed since 558.

According to the contemporary historian Evagrius Scholasticus, the two Justins had reached an agreement whereby whoever would be crowned emperor would make the other the "second man" in the empire.

When Justin II recalls his cousin to Constantinople, it seems that this is the reason.

The general is warmly received at first, but soon the new emperor begins to make accusations against him, dismisses his bodyguard and places him under house arrest, before sending him to exile in Alexandria, ostensibly as the new augustal prefect of Egypt.

The general Justin is murdered in his sleep in Alexandria in 565, ostensibly because he was plotting to seize the throne, and his head is cut off and brought to Constantinople.

In reality, he was too great a threat to the new emperor to be left alive; the Visigoth chronicler John of Biclaro explicitly attributes the murder to the wife of Justin II, the Empress Sophia.

Alboin, faced with the possibility of annihilation, makes an alliance in 566 with the Avars under Bayan I, at the expense of some tough conditions; the Avars demand a tenth of the Lombards' cattle, half of the war booty, and on the war's conclusion all of the lands held by the Gepids.

The Lombards play on the pre-existing hostility between the Avars and Constantinople, claiming that the latter is allied with the Gepids.

Cunimund, on the other hand, encounters hostility when he once again asked the Emperor for military assistance, as Constantinople has been angered by the Gepids' failure to cede Sirmium to the empire, as had been agreed.

Moreover, Justin II is moving away from the foreign policy of Justinian, and believes in dealing more strictly with bordering states and peoples.

Attempts to mollify Justin II with tributes fail, and as a result the Empire remains neutral if not outright supportive of the Avars.

The Avars do defeat Sigebert in 566 but have nonetheless to stop; in the meantime the Göktürks, in pursuit of their former subjects, remain a real danger.

The Avars, traditionally a nomadic people, desperately need both shelter and pasture for their livestock, but the route to Pannonia is blocked by impassable mountains covered with thick forests: the Carpathian range.

It is in the critical winter of 566-567 that the Avars, stuck in what is now eastern Germany, are sent feelers by Alboin, the strong ruler of the Lombards and brother-in-law of Sigebert, who seeks an alliance to crush his old enemies the Gepids.

These last ones, by chance, control the only practical way from the Lower Danube to the Pannonian pastures craved by the Avars, who are skilled in a sort of perfidious diplomacy that will help them pursue their objectives.

The refusal of Justin II to continue the payment of tribute to Avar or Persian preserves the resources of the treasury, which he further increases by levying new taxes.

Praiseworthy as his refusal to submit to blackmail may seem, Justin's intransigence only increases the menace to the empire.

John III, patriarch of Constantinople, organizes a compromise between the Chalcedonians and Monophysites.

Cunimund makes the same offer to Justin II as he had before, and this time when Justin accepts, the Gepid king hands Sirmium over to the Empire.

As it turns out, however, the imperial troops neglect to join the Gepids in their fight but keep Sirmium, and although the Avars do not show up either, the Lombards soundly defeat Cunimund in 567, crushing their foes in a pincer movement.

According to the writings of Paul the Deacon, Alboin killed the defeated king and had his skull converted into a drinking cup known as a scala or patera.

The Avars now conquer Transylvania, and the surviving Gepidae are hereafter absorbed into the Lombard nation or become submerged in Avar domains.
