Widonids
noble family

The Widonids (Italian: Guideschi) were an Italian family of Frankish origin prominent in the 9th century.
They were an aggressive dynasty that expanded their power base, the Duchy of Spoleto, at the expense of the neighboring Papal States and in alliance with the Carolingian dynasty, to whom they were related through the female line. Through this relation, the Widonids were able to aspire to the imperial throne. The Widonids and the Rorgonids competed for control of the Breton March through much of the ninth century.
The first member of the family to attain prominence was Lambert's son Guy I, who was made duke of Spoleto by the Emperor Lothair I in 842. He was active in Lotharingia and Italy, even marrying a local Lombard woman, Itta (or Itana), the daughter of Sico of Benevento. His descendants continued to rule Spoleto until 897.
The most famous Guidoni were Guy III and his son Lambert II. Both became kings of Italy and emperors. Guy IV of Spoleto also became Duke of Benevento.

This brief starts where responsible research should: with the source description of “Widonids” as noble family. 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 noble family. Its deeper value depends on whether names, dates, institutions and citations support that framing.
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 Aug 22, 2026. The linked authority identifier is Q1553748. None of the 0 selected statements returned an explicit reference.
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.
