Reichsgau Oberdonau
The Reichsgau Upper Danube (German: "Reichsgau Oberdonau") was an administrative division of Nazi Germany, created after the Anschluss (annexation of Austria) in 1938 and dissolved in 1945. It consisted of what is today Upper Austria, parts of Southern Bohemia, and a small part of the Salzkammergut which was annexed from Styria. The Gau had the honorary title of "Home Gau of the Führer" (), since Adolf Hitler was born in Braunau am Inn and spent much of his early life in Linz. His home Berghof was located in neighboring Gau Munich-Upper Bavaria. History. The Nazi Gau (plural Gaue ) system was originally established in a party conference on 22 May 1926, in order to improve administration of the party structure. From 1933 onwards, after the Nazi seizure of power, the "Gaue" increasingly replaced the German states as administrative subdivisions in Germany. On 12 March 1938 Nazi Germany annexed Austria and on 24 May the Austrian provinces were reorganized and replaced by seven Nazi party "Gaue." Under the Ostmarkgesetz law of 14 April 1939 with effect of 1 May, the Austrian "Gaue" were raised to the status of "Reichsgaue" and their Gauleiters were subsequently also named "Reichsstatthalters". At the head  of each Gau stood a Gauleiter, a position which became increasingly more powerful, especially after the outbreak of the Second World War. Local Gauleiters were in charge of propaganda and surveillance and, from September 1944 onwards, the Volkssturm and the defence of the Gau. The position of Gauleiter in Upper Danube was held by August Eigruber for the duration of the existence of the Reichsgau. The Mauthausen-Gusen concentration camp was located in the Reichsgau Oberdonau. Of the 199,404 prisoners that were sent to the camp 119,000 died in the harsh conditions of the camp through overwork, malnourishment and exhaustion
