The Griffin dynasty refers to a noble family that ruled parts of Pomerania in northern Poland and Germany from the 12th to the 17th centuries. The dynasty is known for its influence in the region, particularly in the development of towns and trade. The Griffins played a significant role in the political landscape of Central Europe during the Middle Ages. The dynasty's most notable members include Duke Bogislaw IV and Duke Barnim I, who expanded their territories and strengthened their power. The Griffin dynasty eventually declined, leading to the integration of their lands into the Duchy of Pomerania and the Holy Roman Empire.
