The territory of New Western Pomerania corresponded to that area of earlier region of Swedish Pomerania that had been left after the Treaty of Stockholm in 1720; thus it covered Western Pomerania north of the Peene, including the island of Rügen.
As early as 1720, the area of Swedish Pomerania that had been ceded to Prussia was called, by contrast, Old Western Pomerania (Altvorpommern).
New Western Pomerania was part of the Prussian province of Pomerania and, from 1818, formed the government region of Stralsund, but for a time, retained a special legal status.
For example, from the old councils (Stände) of New Western Pomerania, a new Regional Parliament for New Western Pomerania and Rügen (Kommunallandtag von Neuvorpommern und Rügen) was formed in 1823, which existed until 1881.
[3] With the gradual loss of its special status, the name New Western Pomerania also became uncommon.
