Source-derived summary

Maria of Nassau or Maria of Orange-Nassau (5 September 1642 – 20 March 1688) was a Dutch princess of the house of Orange and by marriage pfalzgräfin or countess of Simmern-Kaiserslautern.

Life

Maria was born in The Hague, the youngest daughter of Amalia of Solms-Braunfels and her husband Frederick Henry, Prince of Orange. Her father was already in his late fifties when she was born and died when she was only four. She was also the aunt of the future William III, via her older brother William II. Since Spain was at war with Portugal and wanted to avoid an Anglo-Portuguese alliance, the Spanish government proposed Princess Maria of Orange-Nassau as a bride for Charles II of England, instead of Catherine of Braganza. However, Charles II dismissed the proposal and chose to establish an anti-Spanish alliance with Portugal and, therefore, he decided to marry Catherine and not Maria. The Orange family also began negotiations for her to marry Charles II of England, but he also refused. A year later marriage negotiations with John Maurice, Prince of Nassau-Siegen began, but these also proved abortive.

On 23 September 1666 in Kleve she married Louis Henry, Count Palatine of Simmern-Kaiserslautern (1640-1674), son of Louis Philip and a grandson of Maria's aunt Countess Louise Juliana of Nassau. Like her sisters' marriages, Maria's marriage was intended to draw the network of Calvinist princes closer together. Maria and Louis Henry were married eight years but the marriage proved childless and on her husband's death the Simmern-Kaiserslautern line died out.

Editorial summary

Begin with the source’s own compact description: “Maria of Orange-Nassau” is open-knowledge reference entry. The dossier treats that line as a proposition to test through Maria, Orange-Nassau and Open-knowledge, not as a finished interpretation.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1642, 1688, 1666, 1640—that can be checked directly. The authority record carries competing date values—1642-09-05, 1642—which should remain separate until their references and qualifiers are resolved. For this dossier, Maria, Orange-Nassau and Open-knowledge is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “open-knowledge reference entry” 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

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 Jun 8, 2026. The linked authority identifier is Q528962. VIAF identifies the subject as 7885159337549113150009. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 1 use preferred rank. The first chronological checks are 1642, 1688, 1666 and 1640.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.

How to read it
