Question: How long did the Egyptian revolution of 2011 take place? 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.
