Input: Consider Input: Question: How long was the Nazi Party around for before Stahlecker joined it? Passage:On 1 May 1932, Stahlecker joined the Nazi Party (no. 3,219,015) as well as the SS (no. 73,041). On 29 May 1933, he was appointed deputy director of the Political Office of the Württemberg State Police. In 1934, he was appointed head of the Gestapo in the German state of Württemberg and soon assigned to the main office of the Sicherheitsdienst (SD). On 11 May 1937, he became head of the Gestapo in Breslau. After the incorporation of Austria in 1938, Stahlecker became SD chief of the Danube district (Vienna), a post he retained even after being promoted to SS-Standartenführer. In the summer of 1938, Stahlecker became Inspector of the Security Police in Austria, succeeding Gestapo chief Heinrich Müller in that position. As of 20 August 1938, Stahlecker was the formal head of the Central Agency for Jewish Emigration in Vienna, though its de facto leader was Adolf Eichmann. Differences of opinion with Reinhard Heydrich motivated Stahlecker to move to the Auswärtiges Amt (Foreign Office), after which he held posts as the commander of the Security Police and SD in the Protectorate of Bohemia and Moravia under SS-Brigadeführer Karl Hermann Frank. In mid-October 1939, Eichmann and Stahlecker decided to begin implementation of the Nisko Plan.

Input: Consider Input: Question: How many teams are in the leagues which compete for the cup annually? Passage:In 2002, the International Ice Hockey Federation (IIHF) announced that it would acknowledge the site of Victoria Rink with "a commemorative plaque or other historical site marker to remind the passers-by of the existence of the Victoria Skating Rink, the birthplace of organized hockey." The commemoration has been marked in two ways. On May 22, 2008, a commemorative plaque was dedicated at the nearby Centre Bell, along with a plaque honouring James Creighton. Further, the IIHF created the Victoria Cup, a trophy named for the arena, for which—along with 1 million Swiss francs—one National Hockey League team and the champion of the European Champions Hockey League play-off annually. The first Cup match was held in Berne, Switzerland on October 1, 2008 between the New York Rangers and the Metallurg Magnitogorsk. The next, and last, edition of the Victoria Cup was held in Zurich on September 29, 2009, between the ZSC Lions and the Chicago Blackhawks.
