Notes about Barnum I OF POMERANIA

Barnim I the Good (c.1217/1219 - December 13, 1278) from the Griffin dynasty was a Duke of Pomerania (ducis Slauorum et Cassubie) from 1220 until his death.

Son of Duke Bogislaw II and Miroslawa, daughter of Duke Mestwin I of Pomerelia, he succeeded to the Duchy of Pomerania-Stettin upon his father's death in 1220; he had however to share the rule of Pomerania with his cousin Wartislaw III, who resided at Demmin. A minor when his father died, his lands until about 1226 were under regency of his mother Miroslawa from the Pomerelian Samborides dynasty. At first still a Danish fief, the Pomeranian lands fell back to the Holy Roman Empire after the victory of several North-German princes at the 1227 Battle of Bornhöved. Emperor Frederick II of Hohenstufen in 1231 put the Duchy of Pomerania under the suzerainty of the Ascanian margraves of Brandenburg, disregarding the tenure of the Griffin dynasty, and thereby fueling the long-term Brandenburg-Pomeranian conflict.

After his cousin Wartislaw III had formally accepted the Brandenburg overlordship by the 1236 Treaty of Kremmen, Duke Barnim I came to terms with the mighty Ascanian margraves in the 1250 Treaty of Landin: he confessed himself a Brandenburg vassal and had to renounce the Uckermark region, nevertheless he reached the consent, that the fief of his cousin Wartislaw would remain with the Griffin dynasty upon his death. When Duke Wartislaw III died in 1264, Barnim I was able to unite the whole Duchy of Pomerania under his rule. He promoted the Ostsiedlung by introducing German settlers and customs into the duchy, established many towns, among them Prenzlau, Szczecin, Gartz, Anklam, Stargard, Gryfino, Police, Pyrzyce, Ueckermünde and Goleniów. He was also known for his generous ecclesiastical foundations, and supported the extension of the secular reign of the Cammin bishops in the Kolobrzeg area.

Duke Barnim died at the town of Dabie (Altdamm), today part of Szczecin. The Minnesinger Meister Rumelant wrote a dirge in his honour.

About 1238 Barnim married Marianne (d. 1252), formerly identified as a daughter of King Eric X of Sweden, secondly Margaret (d. 1261), and for the third time Matilda, a daughter of Margrave Otto III of Brandenburg, in 1267.

His eldest son Bogislaw IV was co-ruler from 1276 and sole ruler after Barnim's death, sharing power with Barnim's younger sons by his third marriage, Barnim II and Otto I, from the 1290s.
