On Jan. 25, 2011, Egyptians took to the streets, protesting the repressive rule of President Hosni Mubarak. After 18 days, the dictator was gone. But two years later, many Egyptians say nothing has changed except the target of their demonstrations: Islamist President Mohammed Morsi. On the second anniversary of their revolution, Egyptians returned to Tahrir Square, sometimes clashing violently with police. For thousands, the revolution remains a work in progress.
