Frederick of Büren
(1020-1068)
Frederick of Büren (fl. 1053) was a count in northern Swabia and an ancestor of the imperial Staufer dynasty.
The name Frederick of Büren is known only from the Tabula Consanguinitatis, a Staufer genealogy drawn up by the monk Wibald in the mid-12th century. Wibald writes that Frederick of Büren was the son of an unspecified Frederick and the father of Duke Frederick I of Swabia, "who built Stauf", the castle from which the family later took its name. Otto of Freising, in his Gesta of the Emperor Frederick Barbarossa, records that Duke Frederick I was descended "from the most noble counts of Swabia" without naming them.
Büren is usually identified with Wäschenbeuren and Frederick with the count of the same name who appears as a witness in a charter of 1053. Also appearing in that charter is the count palatine Frederick, who it is speculated may have been Frederick of Büren's father, since the title of count palatine in Swabia is later found with Frederick of Büren's second son, Louis. Wäschenbeuren lies not far from Stauf.
Frederick's stature in Swabia and neighbouring Alsace is proved by his advantageous marriage. He married Hildegard of Egisheim, a niece of Pope Leo IX. It is generally thought that the Staufer acquired Sélestat through this marriage.
This brief starts where responsible research should: with the source description of “Frederick of Büren” as (1020-1068). 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 (1020-1068). 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 Sep 10, 2025. The linked authority identifier is Q323896. The first chronological checks are 1053.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.
