Tadeusza Manteuffla Polskiej Akademii Nauk}, language={pol}, abstract={The article presents an edition and analysis of an unknown source document from the time of Mieszko the Tanglefoot from 1207–1211. The source was found in a codex of Dominican provenance from the fifteenth century, with the reference number Lat. I F 212, kept in the National Library of Russia in St Petersburg. The document (or a note) contains the text of a confirmation by Duke Mieszko the Tanglefoot that the church of St Adalbert (Wojciech) in Wrocław belongs to the Canons regular monastery of the Blessed Virgin Mary on Sand in Wrocław. The ducal confirmation mentions a war between the sons of Władysław the Exile returning to Silesia (in 1163) and their uncles ruling in Poland: Boleslaw the Curly and Mieszko the Old. Boleslaw the Tall and Mieszko the Tanglefoot defeated their uncles at the Battle of Modlikowice. This information contradicts the opinion, well-established in historiography, of a peaceful return of the Władysław’s sons to their homeland.}, type={Text}, title={Nieznany dokument Mieszka Plątonogiego z 1207–1211 r. : zbrojny powrót synów Władysława Wygnańca na Śląsk}, URL={http://www.rcin.org.pl/Content/237106/WA303_273342_B88-SZ-60-2022_Kowalski.pdf}, keywords={Mieszko I Laskonogi, Duke of Racibórz, 1142?-1211, Mieszko the Tanglefoot, Bolesław IV, Prince of Poland, 1122?-1173, Bolesław the Curly, Silesia, “war for strongholds”, St Mary’s Monastery on the Sand in Wrocław, Canons Regular, Silesia (Poland ; region) - history - 13th century - sources, princes - Poland - Silesia (region) - biography - sources}, }
