Philip Louis, Duke of Schleswig-Holstein-Sonderburg-Wiesenburg
Duke of Schleswig-Holstein-Sonderburg-Wiesenburg (1620-1689)
Philip Louis of Schleswig-Holstein-Sonderburg-Wiesenburg (born 27 October 1620 in Beck; died: 10 March 1689 in Schneeberg) was the founder and first duke of the line Schleswig-Holstein-Sonderburg-Wiesenburg. His branch of the House of Schleswig-Holstein-Sonderburg is named after Wiesenburg Castle, near Zwickau.
Life
Philip Louis was the youngest son of Duke Alexander of Schleswig-Holstein-Sonderburg (1573–1627) from his marriage to Dorothea (1579–1639), daughter of Count John Günther I of Schwarzburg-Sondershausen.
Philip Louis spent his youth at various courts in Hesse. In 1663 he acquired the district of Wiesenburg, with Wiesenburg Castle and the city of Kirchberg and 20 villages from Elector John George II of Saxony, with whom he had a very good relationship. Wiesenburg Castle became his seat and gave its name to his family line.
In 1668, he appointed Johann Winckler to educate his sons at the Wiesenburg Castle. He invested in the mining industry in Schneeberg and Neustädtel. Initially, it appeared to be a failure, but in the 1670s he made large profits and became a wealthy mining entrepreneur. He had his castle thoroughly renovated.

Why this record matters

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 Jul 11, 2026. The linked authority identifier is Q108992. VIAF identifies the subject as 95405063. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1620, 1689, 1573 and 1627.
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.
