Local Christians in 547 massacre Samaritans and …

…Jews.

Belisarius recaptures Rome from the Ostrogoths but his Italian campaign is unsuccessful, starved as it is of supplies and reinforcements from Constantinople.

John Troglitas decisively defeats Antalas and his allies in early 547 and drives them from Byzacena.

As Procopius recounts: And this John, immediately upon arriving in Libya, had an engagement with Antalas and the Moors in Byzacium, and conquering them in battle, slew many; and he wrested from these barbarians all the standards of Solomon, and sent them to the emperor—standards which they had previously secured as plunder, when Solomon had been taken from the world.

—Procopius, The Vandalic War II.XXVIII A few months later, however, the tribe of the Leuathae (Laguatan), in Tripolitania, rises up, and inflicts a severe defeat upon the imperial forces in the plain of Gallica.

John Troglita flees to …

…Lunci (nine kilometers south of Mahares) and is forced to withdraw north to …

Some of the Angles of what will come to be called Bernicia may have been employed as mercenaries along Hadrian's Wall during the late Roman period.

The first Anglian king in the historical record is Ida, who is said to have obtained the throne and the kingdom about 547.

The death of the Empress Theodora at forty-eight, probably of breast cancer (according to bishop Victor of Tunnuna), subtracts both intensity and purpose from Justinian’s reign.

Justinian relieves Belisarius from military service in favor of the seventy-year-old general Narses.

Germanus is by 548 acknowledged as the most influential of Emperor Justinian's relatives and his heir apparent, although this is never formally recognized.

In this year, his position is strengthened further by the death of Empress Theodora, who had disliked him intensely.

His stature at court is such that a plot is hatched by the disaffected general Artabanes and his kinsman Arsaces to assassinate Emperor Justinian and replace him with Germanus.

The conspirators think Germanus amenable to their plans, since he has been dissatisfied with Emperor Justinian's meddling in the settling of the will of his recently deceased brother Boraides.

The conspirators first tell Justin, Germanus's eldest son, of their intentions.

He, in turn, informs his father, who then holds counsel with the comes excubitorum, Marcellus.

In order to find out more of their intentions, Germanus meets the conspirators in person, while a trusted aide of Marcellus is concealed nearby and listens in.

Marcellus then informs Emperor Justinian, and the conspirators are arrested, but treated with remarkable leniency.

At first, Germanus and his sons too are suspected, until the testimony of Marcellus clears them.
