The earliest preserved document written in the Romanian language is a 1521 letter that notifies the mayor of Brașov about an imminent attack by the Turks. This document, known as Neacșu's Letter, is also notable for having the first occurrence of "Romanian" in a Romanian text, Wallachia being called here "the Romanian Land"—"Țeara Rumânească" (Țeara < Latin "Terra" = land). As in the case of the ethnonym "român/rumân", Romanian documents use both forms, "Țara Românească" and "Țara Rumânească", for the country name.
