ドイツ騎士団国
At the beginning of the 15th century, the State of the Teutonic Order stood at the height of its power under Konrad (Conrad) von Jungingen. The Teutonic navy ruled the Baltic Sea from bases in Prussia and Gotland, and the Prussian cities provided tax revenues sufficient to maintain a significant standing force composed of Teutonic Knights proper, their retinues, Prussian peasant levies, and German mercenaries.
