  Vienna fell on 13 April 1945, during the Soviet Vienna offensive, just before the total collapse of the Third Reich. The invading Allied powers, in particular the Americans, planned for the supposed "Alpine Fortress Operation" of a national redoubt, that was largely to have taken place on Austrian soil in the mountains of the Eastern Alps. However, it never materialised because of the rapid collapse of the Reich.
  
  Karl Renner and Adolf Schärf (Socialist Party of Austria), Leopold Kunschak (Austria's People's Party), and Johann Koplenig (Communist Party of Austria) declared Austria's secession from the Third Reich by the Declaration of Independence on 27 April 1945 and set up a provisional government in Vienna under state Chancellor Renner the same day, with the approval of the victorious Red Army and backed by Joseph Stalin. (The date is officially named the birthday of the second republic.) At the end of April, most of western and southern Austria were still under Nazi rule. On 1 May 1945, the Federal Constitutional Law of 1920, which had been terminated by dictator Dollfuss on 1 May 1934, was declared valid again. The total number of Austrian military deaths from 1939 to 1945 was 260,000. The total number of Jewish Austrian Holocaust victims was 65,000. About 140,000 Jewish Austrians had fled from the country in 1938–39. Thousands of Austrians had taken part in serious Nazi crimes (hundreds of thousands of people died in the Mauthausen-Gusen concentration camp alone), a fact which was officially acknowledged by Chancellor Franz Vranitzky in 1992.
  
  Allied-occupied Austria was after World War II divided into military occupation zones. Austria was governed by the Allied Commission for Austria. As stipulated in the Moscow Declaration of 1943 a subtle difference was seen in the treatment of Austria by the Allies.
  
  The Austrian government, consisting of Social Democrats, Conservatives, and Communists resided in Vienna, which was surrounded by the Soviet zone. This Austrian government was recognised by the allies of World War II in October 1945 despite concerns that Karl Renner could be Stalin's puppet. On 26 July 1946 the Austrian Parliament passed its first nationalization law and approximately 70 mining and manufacturing companies were seized by the Austrian state. The Ministry of Property Protection and Economic Planning (Ministerium für Vermögenssicherung und Wirtschaftsplanung) was responsible for directing the nationalized industries under the directorship of Minister Peter Krauland (party ÖVP).
