The Wartburg remained the seat of the Thuringian landgraves until 1440. thumb|The Luther Room From May 1521 to March 1522, Martin Luther stayed at the castle under the name of Junker Jörg (the Knight George), after he had been taken there for his safety at the request of Frederick the Wise following his excommunication by Pope Leo X and his refusal to recant at the Diet of Worms. It was during this period that Luther translated the New Testament from ancient Greek into German in just ten weeks. Luther's was not the first German translation of the Bible but it quickly became the most well known and most widely circulated.
