Europe

King Liutprand contracts an alliance with Eutychius, exarch of Ravenna, and agrees to support him in his attack on Rome, while subjugating the independent southern Lombard duchies of Benevento and Spoleto.

Tiberius Petasius proclaims himself emperor in Tuscia. Eutychius defeats him with the support of Pope Gregory II, and Tiberius is killed in Monterano, with his head sent to the Byzantine emperor Leo III as a gift.

Charles Martel defeats the last independent dukedom of Alamannia, and incorporates it into the Frankish Empire. He also launches raids on the Saxons beyond the Rhine.

Editorial summary

Begin with the source’s own compact description: “730” 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 201-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 Feb 27, 2026. The linked authority identifier is Q23563. 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.
