Bishopric of Pomesania

The Bishopric of Pomesania (Bistum Pomesanien; Diecezja pomezańska) was a Catholic diocese in the Prussian regions of Pomesania and Pogesania, in modern northern Poland until the 16th century, then shortly a Lutheran diocese, and became a Latin titular see.

The former Cathedral and Castle of Pomesanian Cathedral Chapter complex in Kwidzyn is listed as a Historic Monument of Poland.

Catholic diocese
It was founded as one of four Roman Catholic dioceses in Prussia in 1243 by the papal legate William of Modena.

The bishops, whose seat was Riesenburg (Prabuty), ruled one third of diocesan territory as his temporality. The diocesan cathedral chapter met in the fortified cathedral of Marienwerder (Kwidzyn). In the 1280s the Teutonic Order succeeded to impose the simultaneous membership of all capitular canons in the Order thus winning influence in the diocese and in the capitular elections of the bishops. So the temporality of Pomesania's bishop did not develop the status of a prince-bishopric and was ruled as part of Teutonic Prussia. In 1454, the region was incorporated by King Casimir IV Jagiellon into the Kingdom of Poland upon the request of the anti-Teutonic Prussian Confederation. The Bishop and canons of Pomesania pledged allegiance to the Polish King during the incorporation in March 1454 in Kraków. After the subsequent Thirteen Years' War (1454–1466) between Poland and the Teutonic Order, the region was recognized as part of Poland as a fief held by the Teutonic Knights.

Beginning in 1523 during the Protestant Reformation, the diocese was effectively administered by Lutheran bishops until 1587, when the diocese was secularized by the regent of Ducal Prussia, George Frederick. However the Catholic diocese was only formally suppressed in 1763, having remained vacant since 1524 except for 'temporary' Apostolic administrators since 1601.

The diocesan area outside of Ducal Prussia remained Catholic and on 1601.04.19 joined the Roman Catholic Diocese of Chełmno.
