After the war, Thadden entered politics as a member of the
Deutsche Rechtspartei and of its successor the
Deutsche Reichspartei. As a member of both, he served as a
councilman in Göttingen from 1948 to 1958. He specifically denied any accusations of
neo-Nazism levelled at him, portraying himself as a supporter of
conservative nationalism. due to his prominent opposition to the notion of any German guilt for the Second World War. He moved the party to the right, bringing in policies such as withdrawal from
NATO, a return of
Danzig to a united Germany, wide-ranging reform of the constitution and possibly a second
Anschluss. Although a loyal supporter of his successor,
Martin Mussgnug, Thadden eventually left the NPD in 1975 after
Gerhard Frey, who had previously been a harsh critic of von Thadden, was appointed Federal Administrator of the party. Thadden left active politics in 1974 and worked for a construction-firm, although he remained as chief editor of the
Deutsche Wochenzeitung into the 1980s. in 1981 and 1982. ==Personal life==
