Among the various interpretations, reference to the colonization of East Europe starting from Low Germany is the most plausible one: The "Children of Hameln" would have been in those days citizens willing to emigrate being recruited by landowners to settle in Moravia, East Prussia, Pomerania or in the Teutonic Land. It is assumed that in past times all people of a town were referred to as "children of the town" or "town children" as is frequently done today. The "Legend of the children's Exodus" was later connected to the "Legend of expelling the rats". This most certainly refers to the rat plagues being a great threat in the medieval milling town and the more or less successful professional "rat catchers".
