The Province of Pomerania was a province of Brandenburg-Prussia, the later Kingdom of Prussia. After the Thirty Years' War, the province consisted of Farther Pomerania. Subsequently, the Lauenburg and Bütow Land, Draheim, and Swedish Pomerania south of the Peene river were joined into the province. The province was succeeded by the Province of Pomerania set up in 1815.

The Treaty of Bromberg or Treaty of Bydgoszcz was a treaty between John II Casimir of Poland and Elector Frederick William of Brandenburg-Prussia that was ratified at Bromberg (Bydgoszcz) on 6 November 1657. The treaty had several agreements, including the Treaty of Wehlau, signed on 19 September 1657 by the Brandenburg–Prussian and Polish–Lithuanian envoys in Wehlau. Thus, the Treaty of Bromberg is sometimes referred to as treaty of Wehlau-Bromberg or Treaty of Wehlau and Bromberg.
