Events

By place

Byzantine Empire

Byzantine–Sassanid War: Emperor Maurice, seeing an opportunity to end the prolonged war to the advantage of Constantinople, assists Khosrau II to regain the Persian throne. He sends a Byzantine army (35,000 men) under Narses into Mesopotamia, through Syria. At the same time, an expeditionary force in Armenia advances through Caucasian Iberia into Media (modern Azerbaijan).

Battle of Blarathon: A Persian army of about 40,000 men under King Bahrām VI is defeated, in the lowlands near Ganzak (northwestern Iran), by the Byzantines. Bahrām flees to seek refuge with the Turks in Central Asia, and settles in Fergana. However, after some time, he is murdered by a hired assassin of Khosrau II.

Summer – Maurice begins a series of military expeditions, to defend the Balkan provinces from the Avars and Slavs. He establishes the Danube frontier (Limes Moesiae) from the Delta to the fortress city of Singidunum (Belgrade), and permits the Byzantines to reassert their authority in the interior.

Europe

Agilulf, cousin of Authari (called "the Thuringian"), is raised on the shield (a ceremonial investment) by Lombard warriors in Milan.

Editorial summary

The public source identifies “591” as year. This brief keeps that definition visible, then builds a research path around year.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current 226-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with year providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “591”, the useful work is to connect “year” to the records capable of establishing context and consequence.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 18, 2026. The linked authority identifier is Q33746. None of the 0 selected statements returned an explicit reference.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
