Frederick, Duke of Opava
Co-ruler of Troppau

Frederick, Duke of Opava (Czech: Bedřich Opavský; German: Friedrich von Troppau; c. 1440 – 1470) was a member of the Opava branch of the Bohemian Přemyslid dynasty. He was co-ruler of Opava from 1452 to 1456.
Life
His parents were Duke William of Opava and his wife Salome (d. 1489), and daughter of the Bohemian nobleman Půta III of Častolovice.
After his father died in 1452, his uncle Ernest took up the guardianship of Frederick and his two brothers and two sisters. The three brothers (Frederick, Wenceslas III, and Przemko III) had jointly inherited two thirds of the Duchy of Opava. The remaining third was held by their cousin John II. Their father had held the Duchy of Münsterberg for a while, however, Frederick and his brothers did not inherit it, because their father had swapped it with Ernest for the latter's third of Opava. Ernest, in his capacity as their guardian, sold the brothers' two-thirds of Opava in 1464 to Duke Bolko V of Opole. John II retained his third.

This brief starts where responsible research should: with the source description of “Frederick, Duke of Opava” as co-ruler of Troppau. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as co-ruler of Troppau. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 26, 2026. The linked authority identifier is Q185900. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1440, 1470, 1452 and 1456.
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.
