Treaty of Stettin (1653)

The Treaty of Stettin (German: Grenzrezeß von Stettin) of 4 May 1653 settled a dispute between Brandenburg and Sweden, who both claimed succession in the Duchy of Pomerania after the extinction of the local House of Pomerania during the Thirty Years' War. Brandenburg's claims were based on the Treaty of Grimnitz (1529), while Sweden's claims were based on the Treaty of Stettin (1630). The parties had agreed on a partition of the Swedish-held duchy in the Peace of Westphalia (1648), and with the Treaty of Stettin determined the actual border between the partitions. Western Pomerania became Swedish Pomerania, Farther Pomerania became Brandenburgian Pomerania.

During the war, Sweden had occupied the Duchy of Pomerania in 1630. The last Griffin duke Bogislaw XIV died in 1637, his duchy was supposed to be inherited by Brandenburg, who based her claims on in the Treaty of Grimnitz.

This however was hindered by the Swedish presence. The 1648 Peace of Westphalia ended the war, and Pomerania was to be partitioned between Brandenburg and Sweden. The 1650 Treaty of Nuremberg roughly defined the areas that should be under control of Sweden and Brandenburg, respectively.

The precise border was drawn in the 1653 Treaty of Stettin, partitioning the Duchy of Pomerania along a line running east of the Oder river. The areas west of this line (Vorpommern, including Stettin) stayed with Sweden and hence were referred to as Swedish Pomerania. The areas east of the line (Farther Pomerania) were to be transferred to Brandenburg. Half of the customs revenues of the Farther Pomeranian towns were the prerogative of Sweden even after her withdrawal.
