Input: Consider Input: Question: On what date did Morsi take office? Passage:Following the Egyptian revolution of 2011 as part of the regional Arab Spring protests, Mubarak was ousted and the following year Mohamed Morsi who is backed by the Muslim Brotherhood won Egypt's first democractic elections. In 2013 Morsi was removed from power in a coup led by Abdel Fattah el-Sisi. Sisi has called for religious tolerance and has cracked down and banned the Muslim Brotherhood. He has closed thousands of mosques and has banned 'burkinis' on some beaches. A The Economist report in 2017 stated that Egyptians were turning more secular again, with supporters of sharia law dropping by more than half since 2011, people praying less than before, and gender equality now being widely accepted. The government has also acted to preserve its Jewish heritage through the restoration of the abandoned Eliyahu Hanavi Synagogue in Alexandria in 2017.

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.
