Despite his paralysis, Chamberlain whose mind was still sharp, remained active as a writer, maintaining a correspondence with a whole gamut of figures from Admiral Alfred von Tirpitz to the radical anti-Semitic journalist Theodor Fritsch, the leader of the "völkisch" "Hammerbund" ("Hammer League"). From his exile in the Netherlands, the former Kaiser wrote to Chamberlain in 1922 to tell him that thanks to his essays, he had become a Marcionist and now rejected the Old Testament. Wilhelm claimed that on the basis of Chamberlain's work, he now knew that what had become the Old Testament was in fact a Zoroastrian text from ancient Persia (modern Iran) and was therefore "Aryan". The former Kaiser claimed that the Jews had stolen and rewritten this sacred text from the Aryan Persians, ending his letter: "Let us free ourselves from the "Judentum" with its Jawe!" In 1923, Wilhelm wrote to tell Chamberlain of his belief that not only were the Jews "not our religious forebears", but that Jesus was "not a Jew", was instead an Aryan "of exceptional beauty, tall and slim with a noble face inspiring respect and love; his hair blond shading into chestnut brown, his arms and hands noble and exquisitely formed".
