They had moved along the Baltic coast from Holstein to Farther Pomerania, up the Oder river to the Moravian Gate, down the Danube into the Kingdom of Hungary and into the Slovene lands of Carniola. From the mouth of the Vistula river and the Prussian region, the Teutonic Knights by force continued the migration up to Estonian Reval (Tallinn). They had also settled the mountainous border regions of Bohemia and Moravia and formed a distinct social class of citizens in towns like Prague, Havlíčkův Brod (German Brod), Olomouc (Olmütz) and Brno (Brünn).
