Diocese of Samland
The Bishopric of Samland (Sambia) (German: Bistum Samland) was a bishopric in Samland (Sambia) in medieval Prussia. It was founded as a Roman Catholic diocese in 1243 by papal legate William of Modena. Its seat was Königsberg, until 1523 the episcopal residence was in Fischhausen. The bishopric became Lutheran in the 16th century during the Protestant Reformation and was eventually dissolved following the establishment of Ducal Prussia, a Protestant vassal duchy of the Kingdom of Poland.
The territory of the defunct bishopric of Samland came nominally under the jurisdiction of the Roman Catholic bishopric of Warmia in the 17th century, and the title of bishop of Samland was occasionally used by Warmian bishops. Most of the area of the medieval bishopric of Samland became a part of the Russian Kaliningrad Oblast in 1945 and is now under the jurisdiction of the Roman Catholic Archdiocese of Moscow. A small section around the town of Go?dap became a part of Poland and maintains its ties to the Archdiocese of Warmia, being administered by its suffragan diocese of E?k.
Samland cathedral chapter was established in Königsberg in 1285 and was dissolved in the 16th century together with the bishopric. In 1989, it was re-established as the Sambian Collegiate Chapter (Sambian Co-Cathedral Chapter since 1992) in Go?dap.
Diocese is merged into the Bishopric of Pomesania
