 Teupitz probably arose from a medieval Slavic settlement during the "Ostsiedlung" of German peasants and craftsmen.A "Tupcz" fortification was first mentioned in a 1307 deed, issued by Margrave Herman of Brandenburg at Spandau.The Ascanian rulers of Margraviate of Brandenburg had just acquired the estates in the former March of Lusatia from Margrave Dietrich IV of Wettin.
