Source-derived summary

Gerhard VI (c. 1367–1404) was the Count of Holstein-Rendsburg from 1382, and Duke of Schleswig as of 1386.

Gerhard VI was born around 1367, the son of Count Henry II from the Rendsburg line of the House of Schauenburg and Ingeborg of Mecklenburg. After the death, in 1381 or 1384, of his father, who had ruled jointly with Gerhard's uncle Nicholas (Claus), Gerhard and his younger brother Albert II entered into the joint government for their late father. On 15 September 1386 King Olav III of Denmark enfeoffed him with the Duchy of Schleswig, after his uncle Nicholas had resigned from that function.

In 1390 Gerhard and his brother and uncle inherited Holstein-Kiel, including the merged Plön, whose line had been extinct in 1350. After their uncle Nicholas had died in 1397 the brothers divided their possessions, the elder keeping Schleswig and Holstein-Rendsburg, and Albert II receiving Holstein-Segeberg as secundogeniture. In 1403 Gerhard regained Segeberg by way of reversion upon Albert's death in action against Ditmarsh, thus ruling almost the whole of Holstein except of Holstein-Pinneberg. The Duchy of Schleswig and the County of Holstein-Rendsburg were then under one ruler. He fell in the Battle on the Hamme on 4 August 1404 during another attempt to subjugate Ditmarsh.

Editorial analysis

Why this record matters

The phrase “duke of Schleswig and Count of Holstein-Rendsburg” 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 Aug 29, 2026. The linked authority identifier is Q563792. VIAF identifies the subject as 81710680. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1367, 1404, 1382 and 1386.

Critical limits

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.
