Hildebrandt joined the
Nazi Party in February 1925 (membership number 3,653) when it was refounded and, as an early member, he later was awarded the
Golden Party Badge. On 27 March 1925 he was appointed
Gauleiter of Gau Mecklenburg-Lübeck. In September 1925, he became a member of the
National Socialist Working Association, a short-lived group of north and northwest German
Gauleiter, organized and led by
Gregor Strasser, which unsuccessfully sought to amend the
Party program. It was dissolved in 1926 following the
Bamberg Conference. In 1927, Hildebrandt became the founder and editor of a Nazi newspaper, the
Niederdeutscher Beobachter, later also serving as editor of two additional such publications, the
Lübecker Beobachter and the
Strelitzer Beobachter. In 1929, he was again elected to the
Landtag, this time as a Nazi deputy. Briefly suspended as
Gauleiter by
Rudolf Hess in July 1930 for criticism of
Adolf Hitler's alliance with industry, Hildebrandt was reinstated on 31 January 1931 after making a declaration of loyalty to Hitler. He was elected to the
Reichstag in September 1930 as a deputy for electoral constituency 35 (
Mecklenburg) and retained that seat until the fall of the Nazi regime. After the
Nazi seizure of power, he was named
Reichskommissar for the Free States of both Mecklenburg-Schwerin and
Mecklenburg-Strelitz on 24 March 1933. He was subsequently elevated to the new post of
Reichsstatthalter (Reich Governor) of Mecklenburg-Schwerin, Mecklenburg-Strelitz and the
Free City of Lübeck on 26 May 1933. He thus united under his control the highest party and governmental offices in his jurisdictions. On 1 January 1934, the two Free States were combined into a unified
Mecklenburg. From 1933 to 1934, Hildebrandt also served as the leader of the
Nordische Gesellschaft (Nordic Society), which sought to strengthen German-Nordic cultural and political cooperation. He was also made a member of
Hans Frank's
Academy for German Law in 1935. On 1 April 1937, the
Greater Hamburg Act transferred the City of Lübeck to
Gau Schleswig-Holstein and Hildebrandt's Gau was renamed
Gau Mecklenburg. Hildebrandt became a member of the SS (member number 128,802) on 5 December 1933 with the rank of SS-
Oberführer. He was made the honorary commander of SS-
Standarte 22, headquartered in
Schwerin, and was subsequently promoted to SS-
Gruppenführer on 27 January 1934. He was assigned to the staff of the
Reichsführer-SS on 23 January 1936. During the Second World War, he was promoted to SS-
Obergruppenführer on 30 January 1942. Hildebrandt was named
Reich Defense Commissioner for his Gau on 16 November 1942 and, on 25 September 1944, he was made commander of the
Volkssturm (Nazi national militia) in his Gau. Hildebrandt was involved in
involuntary euthanasia for
Aktion T4. In April 1941 he had the deaconess house in
Lübtheen expropriated. The mentally handicapped children living there were then taken to the Lewenberg children's ward in
Schwerin, where they were later murdered. During a meeting on 5 April 1941, Hildebrandt said "I had Lobetal cleaned. I had the idiots taken to where they belong." In the winters of 1941/1942, several thousand Soviet POWs starved to death under Hildebrandt's jurisdiction in Mecklenburg. In a letter to the chancellery, he expressed his concern about the lack of slave labourers, and said the problem could be avoided if "enough Russians are delivered later." During a meeting with the Reich Defense Committee on 17 March 1942, Hildebrandt said "... for the Führer and for Adolf Hitler's cause, I pursue the law, even if it comes down to dead bodies." By the end of 1943, there were 152,148 foreign workers in Mecklenburg, most of whom were there against their will and were being exploited for slave labour. == Post-war prosecution ==
