Events
By place
Byzantine Empire
January 27 – The co-emperors Stephen and Constantine are overthrown barely a month after deposing their father, Romanos I. With the help of his wife, Constantine VII becomes sole emperor of the Byzantine Empire. He appoints to the highest army commands four members of the Phokas family, which have been in disgrace under Romanos.
Constantine VII concludes a Rus'–Byzantine treaty in which Rus' merchants are to conduct their trade in Constantinople. While many Rus' make their fortunes in trade with the Arab Muslims, the Rurik Dynasty of Kiev grows rich from Byzantine commerce.
Europe
Spring – Berengar of Ivrea invades Italy with hired Lombard troops and takes up residence in Milan. Berengar proceeds to Verona, where he is joined by forces of Count Milo and other partisans.
King Hugh of Provence lays siege to Vignola to put an end to Berengar's advance. But to no avail, as Berengar of Ivrea is hailed throughout northern Italy as a liberator, and Hugh flees to Provence.
April 13 – Hugh of Provence abdicates the throne in favor of his son Lothair II (who has been co-ruler since 931) and is acclaimed as sole king of Lombardia.
This brief starts where responsible research should: with the source description of “945” as year. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as year. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 19, 2026. The linked authority identifier is Q24199. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
