Bogislaw XIV, Duke of Pomerania, the last living member of the House of Pomerania, had suffered a stroke already in April 1631. Sweden neither approved nor rejected the Brandenburgian offer.  On 19 November 1634, a "regiment constitution" [nb 9] reformed the administration of the duchy of Pomerania. 
Bogislaw XIV, Duke of Pomerania, pledged his assistance as well, but he was desperately isolated. The Margraviate of Baden as well as William of Hesse also pledged their support.

Following the Capitulation of Franzburg in 1627, the Duchy of Pomerania was occupied by forces of Ferdinand II, Holy Roman Emperor, under command of Albrecht von Wallenstein. The Swedish intervention in the Thirty Years' War began with the active military support of Stralsund, a Pomeranian Hanseatic port which since the Battle of Stralsund successfully resisted imperial occupation with Danish and Swedish support. Sweden and Stralsund concluded an alliance scheduled for twenty years. The Danish campaigns in Pomerania and other parts of the Holy Roman Empire ended with the Battle of Wolgast in 1628 and the subsequent Treaty of Lübeck in 1629. Except for Stralsund, all of Northern Germany was occupied by forces of the emperor and the Catholic League. In 1629, the emperor initiated the Re-Catholization of these Protestant territories by issuing the Edict of Restitution. The Truce of Altmark ended the Polish–Swedish War (1626–1629) in September 1629, releasing the military capacities nee...
The first draft of a Swedish-Pomeranian alliance, which the Pomeranian ducal councillors had worked out since 20 July 1630 (N.S.), was rejected by Gustavus Adolphus of Sweden. A second draft was returned to the council together with a list of modifications Sweden insisted on. On 22 August (N.S.), actual Swedish-Pomeranian negotiations started, which Gustavus Adolphus on 1 September (N.S.) joined in person.The final negotiations lasted from 2–4 September (N.S.). The actual agreement was made on 25 August (O.S.) or 4 September (N.S.), but pre-dated to 10 July (O.S.) or 20 July 1630 (N.S.).[nb 1] The alliance was to be "eternal". The treaty also included the alliance with Stralsund of 1628, which was concluded when the town resisted the Capitulation of Franzburg and was thus besieged by Albrecht von Wallenstein's army. Subsequent treaties were the "Pomeranian Defense Constitution"[nb 4] of 30 August 1630 (O.S.), and the "Quartering Order"[nb 5] of 1631. The Swedish king and the high-ra...

Bridgehead for the Swedish intervention in the Holy Roman Empire
When Gustavus Adolphus landed in Pomerania, the German Protestant nobility met his intervention with distrust. In April 1631, at a convention in Leipzig, they decided to set up a third front on their own, and except for Magdeburg, who had allied with Sweden already on 1 August 1630, did not side with Sweden.In Swedish strategy, Magdeburg was to be the spark inflaming a "universal rebellion in Germany" - yet initially this strategy failed. In early 1631, Swedish forces advanced into Brandenbur...

When peace talks started in Osnabrück to end the Thirty Years' War, a Pomeranian delegation was present in early 1644 and from October 1645 to August 1647. Stralsund had sent her own delegates, and the rest of the duchy was represented by von Eickstedt and Runge, accredited by both Sweden and Brandenburg. On 3 August, George William of Brandenburg's delegation started to negotiate a partition of the duchy with Sweden. While the Pomeranian nobility in October rejected a partition and urged Brandenburg to look for alternatives, the partition was made definite on 28 January 1647 in Osnabrück, signed as Peace of Westphalia on 24 October 1648: Western Pomerania was to remain with Sweden, while Farther Pomerania was to become a fief of Brandenburg.

The dispute was ended in 1526 when King Sigismund I the Old gave the area as a nearly unconditional fief ("libere a servitio et a iuramento") to Duke Georg I of Pomerania. The only condition was that the dukes had to send an official to the coronations of Sigismund's successors, who would reassure the dukes of the fief.
