Academic literature on the topic 'Hauptabteilung XX'

Research objectives: This article offers annotated editions of nine letters from the archive of the grand masters of the Teutonic Order written between the spring of 1431 and the summer of 1432 concerning the Tatars. Research materials: The originals and copies of the letters preserved in the Geheimes Staatsarchiv Preußischer Kulturbesitz in Berlin – the historical Königsberg archive (XX. Hauptabteilung), subsidiary materials, published and unpublished, from the same archive, as well as materials from the archives of Cracow and Warsaw. Results and novelty of the research: It is established that at least nine letters written between the spring of 1431 and the summer of 1432 concerning the Horde’s relations with its neighbors (the Grand Duchy of Lithuania, the Kingdom of Poland, Moldavia, and Walachia) and its ongoing internal power struggle are preserved in the historical Königsberg archive, presently named the Geheimes Staatsarchiv Preußischer Kulturbesitz, in Berlin. Only three of them have been hitherto published in full and in keeping with modern scholarly standards. The remaining six letters are published here along with the descriptions of their originals and copies besides detailed annotations.
