Drang nach Osten (German: [ˈdʁaŋ nax ˈʔɔstn̩], "Drive to the East",[1] "push eastward",[2] "drive toward the East"[3] or "desire to push East"[4]) is a term that was coined in the 19th century in order to designate German expansion into Slavic lands.[3] The term became a motto of the German nationalist movement in the late 19th century.[5] In some historical discourse, Drang nach Osten combines historical German settlement in Central and Eastern Europe, medieval (12th-13th-century)[6] military expeditions like those of the Teutonic Knights (see Northern Crusades), and Germanisation policies and warfare of modern German states such as those which reflected Nazism's concept of Lebensraum.[2][7]
