Barnim I the Good (c. 1217/1219 – 13 November 1278), from theGriffin dynasty, was a Duke ofPomerania (ducis Slauorum et Cassubie) from 1220 until his death.
Son of DukeBogislaw II andMiroslava of Pomerelia, he succeeded to the Duchy of Pomerania-Stettin upon his father's death in 1220;[1] he had, however, to share the rule of Pomerania with his cousinWartislaw III, who resided atDemmin. Because he was minor when his father died, until about 1226 his lands were under the regency of his mother Miroslawa from the PomerelianSamborides dynasty. At first still aDanish fief, the Pomeranian lands fell back to theHoly Roman Empire after the victory of several North-German princes at the 1227Battle of Bornhöved. EmperorFrederick II of Hohenstaufen in 1231 put the Duchy of Pomerania under thesuzerainty of theAscanian margraves ofBrandenburg, disregarding the tenure of the Griffin dynasty, and thereby fueling the long-termBrandenburg–Pomeranian conflict.
After his cousin Wartislaw III had formally accepted the Brandenburg overlordship by the 1236Treaty of Kremmen, Duke Barnim I came to terms with the mighty Ascanian margraves in the 1250Treaty of Landin: he confessed himself a Brandenburg vassal and had to renounce theUckermark 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 theOstsiedlung by introducingGerman settlers and customs into the duchy, established manytowns, among themPrenzlau,Szczecin,Gartz,Anklam,Stargard,Gryfino,Police,Pyrzyce,Ueckermünde andGoleniów. He was also known for his generous ecclesiastical foundations,[1] and supported the extension of the secular reign of theCammin bishops in theKołobrzeg area.
Duke Barnim died at the town ofDąbie (Altdamm), today part of Szczecin. TheMinnesingerMeister Rumelant wrote adirge in his honour.
Between 4 September 1238 and 18 July 1242, Barnim I married firstly with Marianna (d. 27 June 1252), whose parentage is disputed: she was either identified as a daughter of KingEric X of Sweden,[2] or a member of theHouse of Ascania as daughter of either Count Albert II of Weimar-Orlamünde, CountHenry I of Anhalt orAlbert I, Duke of Saxony. Modern historiography considers that her origins are unknown.[3] They had one daughter:
Between 1253 and 1254, Barnim I married secondly with Margareta (b. aft. 1231 – d. bef. 27 May 1261), probably a daughter ofNicholas I, Lord of Werle and member of theHouse of Mecklenburg,[4][better source needed] although other sources identified her as a daughter ofOttothe Child, Duke of Brunswick-Lüneburg. Historian Robert Klempin identified her as the widow ofVitslav I, Prince of Rügen, but this seems very doubtful from a chronological view.[5] They had one son:
Before 20 May 1267, Barnim I married thirdly withMatilda (b. ca. 1255 – 20 December 1316), a daughter ofOtto III, Margrave of Brandenburg. They had five children:
