For study reasons, Leibbrandt oed for two semestri to Paris and an other semestre to London. It made three travels of study in Ussr and in 1930 scholarship of the foundation worked in the USA thanks to one Rockefeller. In USA it entered in contact with an organization of the NSDAP, contact that ristabill subsequently to Geneva, where it remained until 1933.
To the Leibbrandt age it worked already for the Office of foreign politics (APA) of the NSDAP, whose head was Alfred Rosenberg . The 10 July 1933 Leibbrandt enrolled to the party (ticket n. 1976826) and saw ricompensati its servigi 15 October of the same year, when it was admitted like collaborator to full time in the APA, where gives the 30 July 1935 covered, in reason of its competences - it had travelled to the foreign country, it spoke Russian, ucraino, French and English -, the function of responsible of a central office.
When the territories occupied from the nazis began to having a more and more immense extension and able the administrative and organizational staff to scarseggiare, Hitler designated to Alfred Rosenberg, a man of its continuation from the remoter times, minister of the Territories orientals (not still occupied). 13 November 1941 came announced the creation of the new ministry of the Reich, than insediò to Berlin, at first in the building of the former embassy jugoslava, then in that one of the former Soviet embassy.
Rosenberg assigned to Leibbrandt the Political division, from which the subdivisions depended Political general, Ucraina, Ostland, the Caucasus and Russia, let alone Culture and Press. Corresponsabile Leibbrandt divenne cosl of the criminal regimen of occupation in the western territories of Ussr, that it practiced one political of extermination, but entered also in conflict on the adequacy in the short period and on the ability to last in along of fascist colonial politics.
To the par of other collaborators of the ministry, it inclined for one political more flexible, paventando that the Barbarian repressive regimen could strengthen the resistance and carry to permanent disorders.
The documents do not help to make light us on the reason for which Leibbrandt it has accompanied the secretary of State Meyer to the conference of the Wannsee . Perhaps its presence is explained with a talk between Meyer and Heydrich , of 4 October 1941, to which it had participated also. In that occasion the two high civil employees of the ministry of the occupied Territories had not married the rigorous line of Heydrich, than he did not hold account of issues of economic character, a lot that the head of the RSHA quite thought to equip the assigned ministry of a special one to the Jewish issue, that he would have had to depend on the organism from directed he.
The constant interest demonstrated from the leadership of the SS because it came to them entrusted the how much before direction of entire politics of extermination, of occupation and of germanizzazione in the future Colonies in the East of the continent it was, from last, the cause of the removal of Leibbrandt from its office.
The change of the guard happened in August 1943. The successor of Leibbrandt was one of the collaborating maximums of Himmler, the Obergruppenführer of the SS Gottlob Berger, that he accumulated the new charge with that one of head of the central Office of the SS.
Leibbrandt, that it had lend service in the Wehrmacht, was enlisted in Navy. It survived to the war and it succeeded to avoid also one sentence.
A procedure started against of he from a court of the western Germany was archiviato in 1950.
