further political aims. Information on thousands of people was recorded on index cards and stored at the Brown House. To mark the occasion of Heydrich's December wedding, Himmler promoted him to the rank of SS-Sturmbannführer (major). In 1932, rumours were spread by Heydrich's enemies of his alleged Jewish ancestry. Wilhelm Canaris said he had obtained copies of documents proving Heydrich's Jewish ancestry, but these copies never surfaced. Nazi Gauleiter Rudolf Jordan claimed Heydrich was not a pure Aryan. Within the Nazi organisation such innuendo could be damning, even for the head of the Reich's counterintelligence service. Gregor Strasser passed the allegations on to the Nazi Party's racial expert, Achim Gercke, who investigated Heydrich's genealogy. Gercke reported that Heydrich was "... of German origin and free from any coloured and Jewish blood". He insisted that the rumours were baseless. Even so, Heydrich privately engaged SD member Ernst Hoffmann to further investigate and dispel the rumours. Gestapo and SD In mid-1932, Himmler appointed Heydrich chief of the renamed security service—the Sicherheitsdienst (SD). Heydrich's counterintelligence service grew into an effective machine of terror and intimidation. With Hitler striving for absolute power in Germany, Himmler and Heydrich wished to control the political police forces of all 17 German states. They began with Bavaria. In 1933, Heydrich gathered some of his men from the SD and together they stormed police headquarters in Munich and took over the organisation using intimidation tactics. Himmler became the Munich police chief and Heydrich became the commander of Department IV, the political police. In 1933, Hitler became Chancellor of Germany, and through a series of decrees became Germany's Führer und Reichskanzler (leader and chancellor). The first concentration camps, which were originally intended to house political opponents, were established in early 1933. By year's end there were over fifty camps. Hermann Göring founded the Gestapo in 1933 as a Prussian police force. When Göring transferred full authority over the Gestapo to Himmler in April 1934, it immediately became an instrument of terror under the SS's purview. Himmler named Heydrich to head the Gestapo on 22 April 1934. On 9 June 1934, Rudolf Hess declared the SD the official Nazi intelligence service. Crushing the SA Beginning in April 1934, and at Hitler's request, Heydrich and Himmler began building a dossier on Sturmabteilung (SA) leader Ernst Röhm in an effort to remove him as a rival for party leadership. At this point, the
