Maria of Masovia
politician
Maria of Masovia (pl: Maria mazowiecka; 1408/15–14 February 1454) was a Duchess of Pomerania by marriage to Bogislaw IX, Duke of Pomerania, and regent of Pomerania from 1446 to 1449.
Life
She was the sixth daughter of Siemowit IV, Duke of Masovia and Alexandra, a daughter of Algirdas, Grand Duke of Lithuania and sister of King Władysław II Jagiełło of Poland.
In Poznań on 24 June 1432, Maria married Bogislaw IX, Duke of Pomerania-Wolgast-Słupsk in Stargard, the first cousin and designated heir of Eric of Pomerania, King of Denmark, Norway and Sweden. The marriage strengthened the alliance between Bogislaw IX and King Władysław II Jagiełło against the State of the Teutonic Order, who feared losing the coastal land connecting them with the Holy Roman Empire. For this, the Order tried to prevent the wedding, and Bogislaw IX had to arrive in Poznań dressed like a pilgrim.
After her husband's death on 7 December 1446, Maria became the regent of his domains until 1449, when the male heir, ex-King Eric, returned from Gotland to rule after being deposed from his three Kingdoms 10 years earlier.
Maria died on 14 February 1454. She was buried in the Chapel of Słupsk Castle. During renovations in 1788 her sarcophagus was found and burned.
Issue
Sophie of Pomerania (1435 – 24 August 1497), married Eric II, Duke of Pomerania.
This brief starts where responsible research should: with the source description of “Maria of Masovia” as politician. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the people & ideas register because the source frames it as politician. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Sep 9, 2025. The linked authority identifier is Q3847623. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1408, 1454, 1446 and 1449.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. 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.
