Duchy of Cosel

from Wikipedia, the free encyclopedia

The Duchy of Cosel (Polish : Księstwo kozielskie ; Czech : Koselské knížectví ) was part of the Duchy of Bytom from 1281 and an independent duchy from 1286. It was ruled by dukes from the Opole line until 1355 , then by dukes from the Oels branch of the Glogau line of the Silesian Piasts until 1492 . The place of residence was the city of the same name, Cosel (today in the Polish Voivodeship of Opole ).

history

The Duchy of Cosel was established in 1281 as a result of the division of the Duchy of Ratibor-Opole after the death of Duke Wladislaus I. The areas of Beuthen and Cosel were given to his second-born son Casimir II of Beuthen , who from 1286 also called himself Duke of Cosel . Already at the beginning of his reign he turned politically to Bohemia and was the first Silesian duke to honor the Bohemian King Wenceslaus II in Prague on January 10, 1289. At the same time, with the consent of his sons, he took over his land as a fiefdom of the crown of Bohemia . His second-born son, Wladislaus († 1351/52), was documented as Duke of Cosel while Kasimir was still alive . After the death of his father in 1312, Wladislaus Cosel initially reunited with Beuthen, but later transferred it to his son Casimir III. († 1347), who officiated as Duke of Cosel. He was followed by his brother Boleslaus († 1355) von Beuthen, who reunited both parts.

Then there was a long-term dispute between the Oelser and the Teschen dukes over the Beuthen-Cosel inheritance, which had fallen back to the Crown of Bohemia as a settled fiefdom . Nevertheless, the four representatives of the main line of Opole raised Casimir I of Teschen , Johann I of Auschwitz († 1370/72), Boleslaus II of Opole and Bolko I of Falkenberg , whose son Wenzel was engaged to Boleslaus daughter Euphemia († 1411) , Inheritance claims to the fallen duchy. Even Conrad I († 1366) of Oels, who was married for 1328/29 with Euphemia († 1376/78), a subsidiary of Duke Władysław of Bytom and Cosel, filed for claims.

On October 10, 1355, an arbitration court chaired by the Bohemian sovereign Charles IV awarded the Duchy of Cosel to Duke Konrad I of Oels. The dispute over the inheritance of the Duchy of Beuthen was only settled in 1369 after the death of Duke Konrad I von Oels, who died in 1366.

Cosel Castle

In 1489, King Matthias Corvinus conquered Cosel. After his death in 1490 Cosel was returned to the rightful heir Konrad X. "the young white man" . Since the Oels line of the Glogau Piasts expired with him in 1492, Cosel again fell to the Crown of Bohemia as a settled fiefdom. King Vladislav II sold it in 1509 to Duke John II , who linked it to his Duchy of Opole. Since he was the last of his tribe, Cosel and Opole fell again to the Crown of Bohemia after Johann's death in 1532.
