The German Order of the Holy Virgin Mary, better known here under the name Teutonic, in domestic (and not only) historiography, fiction and cinematography, frankly, was not lucky. Almost everyone from childhood remembered the expression "dogs-knights," although in the Russian annals these "dogs" were called much more respectfully - "God's nobles" or "God's servants." With the word "Teutonic" in the mind of many, a negative associative series immediately arises: The battle of the ice - the iron pig - the cradle of the aggressive Prussian Junker state - the forerunner of German fascism... What really lies under the name "Teutonic Knights"? What are their ideals that they were willing to sacrifice their lives for without hesitation?
