Henry the Long
margrave of the Nordmark, Count of Stade

Henry the Long (c. 1065 – 27 June 1087) was Margrave of the Nordmark (numbered Henry I) and Count of Stade (numbered Henry III). He was son of Lothair Udo II, Margrave of the Nordmark, and Oda of Werl, daughter of Herman III, Count of Werl, and Richenza of Swabia.
Henry married Eupraxia of Kiev, daughter of Vsevolod I, Grand Prince of Kiev, and his second wife Anna. There were no children as a result of this marriage, and Eupraxia, widowed, married next Henry IV, then King of Saxony, who became Holy Roman Emperor.
Raffensperger suggests that Henry's motivation in marrying Eupraxia was to bring Saxony closer to Kiev. In fact, the marriage may have been arranged by Oda of Stade, daughter of Lothair Udo I, Margrave of the Nordmark, who had married Sviatoslav II, Grand Prince of Kiev.

Why this record matters
The phrase “margrave of the Nordmark, Count of Stade” 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.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Mar 20, 2026. The linked authority identifier is Q2067458. VIAF identifies the subject as 86108250. 1 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1065 and 1087.
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.
