Life

Barnim III. was the son of Duke Otto I of Pomerania-Stettin and his wife Elisabeth, the daughter of Count Nikolaus I of Schwerin . From 1320 he was co-regent of his father, who set up his own court for him. After the Brandenburg Ascanians , the previous feudal lords, died out, attempts were made to first give Pomerania-Stettin to the bishop of Cammin and in 1331 to Pope Johannes XXII. to be offered as fiefdom to avoid paying homage to the new Margrave Ludwig since 1323 . Meanwhile, Duke Wartislaw IV of Pomerania-Wolgast died in 1326 , resulting in the First War of the Rügen Succession . Barnim III. and his father took over the guardianship of Wartislaw's three underage sons. Since they had little interest in another military conflict besides the one with the Brandenburgers, they negotiated the peace of Brudersdorf in 1328 with the Mecklenburg opponents who had lost in the most important battles .

In 1329 the Pomeranian-Brandenburg War broke out , in which Barnim III. in alliance with the Bishop of Cammin and Count Hermann von Eberstein-Naugard, defeated the Brandenburgers near Prenzlau. The armistice of January 1331 lasted until mid-1331 or 1332, then Barnim III marched. entered the march with an army. He pursued the Brandenburgers defeated at Kremmer Damm as far as Berlin. Finally, on June 28, 1333, the peace of Lippehne was concluded. It was not until 1338 that King Ludwig IV succeeded in achieving recognition of the imperial immediacy of Pomerania-Stettin . In return, the Duchy of Szczecin granted the Brandenburg margrave the right of repudiation; if the Szczecin Griffin family had died out , Pomerania-Szczecin would have fallen to Brandenburg. As a result, the dukes of Pomerania-Wolgast saw their inheritance claims endangered and several towns in Barnim's domain turned against him. By 1343, however, he managed to resolve the conflict.

From 1344 or 1345 onwards, Barnim had a new castle built, initially against the will of the Stettiners. On June 4, 1348, he personally obtained confirmation of Pomerania's imperial immediacy from King Charles I of Bohemia . At the same time he provided military support to False Waldemar , who was enfeoffed by the King with the Mark Brandenburg, and conquered the eastern parts of the Uckermark , which remained in his possession after Waldemar was deposed and a settlement with Margrave Ludwig.

During the Second War of the Rügen Succession , he moved with a relief army to Pommern-Wolgast and defeated the Mecklenburgers in 1351 in the Battle of Schoppendamm near Loitz . In the following years, Barnim III. to consolidate his rule in Pomerania-Stettin and allied himself with his Wolgast relatives as well as the dukes of Mecklenburg and the margrave of Brandenburg.

Barnim was married to Agnes von Braunschweig (1318-1371), a daughter of Duke Heinrich II of Braunschweig-Grubenhagen . They had four sons. In addition to Otto, who died young, these were Casimir III. (IV.) , Swantibor III. (I.) and Bogislaw VII. , Who succeeded their father in the rule in 1368.
