Source-derived summary

Year 671 (DCLXXI) was a common year starting on Wednesday of the Julian calendar. The denomination 671 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

December 7 – An annular solar eclipse is visible from Tibet to the Maghreb.

By place

Europe

Perctarit returns to Lombardy from exile and reclaims his realm, which is being ruled on behalf of Garibald, since his father King Grimoald I died. He deposes the young king, and becomes the new ruler of the Lombard Kingdom in Italy. During his reign Perctarit makes Catholicism the official religion, but does not recognize papal authority. Grimoald is buried in the St. Ambrogio Church (Milan).

Britain

Battle of Two Rivers: King Ecgfrith of Northumbria defeats the Picts under King Drest VI, in the vicinity of Moncreiffe Island, near Perth (Scotland). After the battle the Picts are reduced to slavery, and subject to the yoke of captivity for the next 14 years.

Editorial summary

Begin with the source’s own compact description: “671” is year. The dossier treats that line as a proposition to test through year, not as a finished interpretation.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current 172-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

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Feb 27, 2026. The linked authority identifier is Q30722. 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 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.
