Source-derived summary

Year 604 (DCIV) was a leap year starting on Wednesday of the Julian calendar. The denomination 604 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Events

By place

Byzantine Empire

The Avars regroup after they are almost destroyed; together with the Slavs they start pillaging through the Byzantine provinces, west and south of the Danube. Due to the new Persian war, Emperor Phocas has few imperial troops available to defend the Balkan Peninsula.

Byzantine–Persian War: King Khosrau II captures the Byzantine positions east of the Euphrates; the Persians destroy many cities in the Levant region, after prolonged sieges such as the Byzantine fortress of Dara (modern Turkey).

Europe

Queen Brunhilda of Austrasia conspires to have Berthoald, Mayor of the Palace, assassinated. She convinces King Theuderic II to send him to inspect the royal villae along the Seine. Brunhilda then has the noblemen who actually carried out the murder arrested and killed.

December 25 – Battle of Ėtampes: Theuderic II, with the aid of Berthoald, defeats the Frankish forces under King Chlothar II of Neustria, at Étampes (near Paris).

Britain

Æthelfrith of Northumbria invades Deira and kills its king, Æthelric.

Editorial summary

Begin with the source’s own compact description: “604” is year. The dossier treats that line as a proposition to test through year, not as a finished interpretation.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current 207-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. For this dossier, year is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “year” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 18, 2026. The linked authority identifier is Q31048. None of the 0 selected statements returned an explicit reference.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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.

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.
